faster. Systems which use memory management can have dramatic improvements with slight operating system changes utilizing a few new MC68010 instructions such as "Move to/from Address Space" (MOVES). Systems may see a significant improvement if they heavily utilize multiply, divide and looping operations. Loops run from 23% to 80% faster once the microcode sets up the automatic "loop mode". Such loops benefit particular funP 9u0Bctions such as block moves, character matching and general string manipulation operations, and multiple-precision binary and packed BCD arithmetic. The new MC68010 multiply is 14 clocks faster, and the divide is 32 clocks faster than the MC68000. Programs utilizing (or with the potential of utilizing) such operations can obtain an increase in perfor- mance easily exceeding 10%. An additional "plus" of the MC68010 is the provision of a clear path for the upgrade of current operatiP!:xUng systems to full virtual operating systems utilizing the sophisticated virtual memory processing capabilities of the MC68010 (which is the same virtual environment offered by the 32-bit MC68020). Since the MC68010 is pin-for-pin compatible with the MC68000, *NO* hardware redesign is necessary. Only very minor software changes may have to be made depending on operating system conventions. The MC68010 differs from the MC68000 in that: 1) a generic "vector word" has been added to tP";^Jhe MC68010 stack frame; and 2) the MC68000's "MOVE SR,ea" has been made a privileged operation. Easy software solutions for these two minor differences are: 1) any routines which build exception stacks (e.g. those which dispatch a routine via an RTE instruction) are modified to account for the four word stack frame (the MC68000 uses a three word stack frame); and 2) an exception handler is added to provide for privilege violations generated by the execution of the "MOVE SR,ea" instrP#<=8uctions in the USER state (local Motorola representatives can supply a debugged handler to suit the requirements of any OS). Major operating systems have been ported from the MC68000 to the MC68010 in less than a single day, reflecting the trivial changes required in the super- visory level code. The bottom line is, by upgrading an MC68000 system to an MC68010 system, an increase in system performance is obtained which is equal to that which a system redesign from 10 MHz to 12.5 MHP$=z would provide, but with signifi- cantly less design cost and effort. The "speed-only" upgrade could only achieve, at best, a 25% system improvement, and only if the system memory access time is significantly improved. The MC68010 upgrade offers from 8% to 50% improvement. Note that the speed gained by changing to the MC68010 is achieved with NO change in memory speeds, NO board redesign, and NO higher speed parts installed in the system as would be required to upgrade a system tP%3!o a 12.5 MHz part. --------------------------------------------------------------------------- SIDE NOTES: (1) Commodore-Amiga has provided for the four word stack frame in Exec.

The CHOP programs must be used to make SURE the DeciGEL program is exactly 168 bytes long. You can determine the size of DeciGEL on your system by using the CLI's LIST program. If the size is greater than 168 bytes, CHOP will allow you to truncate (or chop) the file to 168 bytes. CHOP.BAS operates with ABasiC (not AmigaBASIC), and CHOP.C is the source of a "C" program; use either one as apPD| propriate for your needs. With the MC68010 installed and DeciGEL "wedged", your Amiga should operate anywheres from 4% to 50% faster depending on what you're doing. Note that the "Boing!" demo will not be faster since its timing is synchronized to the vertical framing of the monitor's clocking which is FIXED per NTSC TV standards! The biggest benefits of the MC68010 upgrade will occur with heavy number-crunching applications, such as spread sheets and Mandelbrot picture generationPE s.

M68000 MICRO MINUTES (c) Motorola MM-444-02 Advantages of Upgrading an MC68000 to an MC68010 There are several ways a system's performance can be upgraded. Some are software related, such as lowering operating system overhead, obtaining better quality language compilers, wisely designing application programs, and coding applications more efficiently. PFG Others are hardware related, such as adding memory, improving I/O channel data rates, increasing mass storage speed and capacity, reducing memory access times, and upgrading the system processor's clock frequency. When considering an MC68000 system upgrade to higher performance, the obvious thought is to redesign for a higher frequency MC68000. For example, a current MC68000 system running at 10 MHz could be redesigned to run at 12.5 MHz, thereby increasing system throughput by 25PG'G%. The "obvious solu- tion", however, is not necessarily the most appropriate or cost-effective once several factors are taken into consideration and alternative solutions examined. The speed-up of a system clock will not be effective unless the system's memory access time is also improved. The performance of the MC68000 is strictly limited by the bus speed, and if no improvement in memory speeds are available, then an increase in system clock speed will lead to negligible improvPH ement in the overall result. A 10 MHz processor running with no "wait states" utilizes a 400 nS bus cycle (4 clocks x 100 nS/clock). This same bus cycle timing, however, leads to a wait cycle on a 12.5 MHz processor (4 clocks x 80 nS/clock + 80 nS of idle time). Thus, the bus performance is exactly the same, but the faster processor is idled for one complete clock cycle. Since a decrease in the bus cycle time provides a directly proportional increase in processor throughput (untilPIリ, of course, the memory cycle becomes faster than the fastest processor bus cycle), the 12.5 MHz processor has no relative performance advantage over the 10 MHz system. The bottom line, then, is that in order to be effective, a higher speed processor must run with fewer or the same number of "wait states". This normally requires a redesign of the memory subsystem to improve the memory access time. Referring to the MC68000 Data Manual (ADI-814-R4), the memory access re- quirements fPJ]M#or the various speed processors can be examined. The effective memory access time (Taccs) of the MC68000 to a memory array (from assertion of Address Strobe [-AS] to data valid) is: Taccs = Tch + 2Tcyc - Tchs1 - Tdic1 + (n * Tcyc) where: Tch is the clock high time (system dependent) Tcyc is the clock period of the processor clock Tchs1 is the delay time from the rising edge of the clock to the assertion of address strobe PKB Tdic1 is the data input set-up time prior to the falling edge of the clock n is the number of wait cycles in the system Assuming a symmetric clock (50% duty cycle), the memory speed required for a no "wait-state" bus cycle for a 19 Mhz MC68000 processor is 185 nS (50 + 200 - 55 -10 + 0). This bus speed can be easily realized with readily available 150 nS dynamic RAMs and careful system design. However, with the same assumptions, the memory speePL\Qd required for a no "wait-state" bus cycle on a 12.5 Mhz processor is reduced to 135 nS (40 + 160 - 55 - 10 + 0) which presents an obvious problem to the cost-conscious system designer -- lack of cost-effective, large capacity 100 nS RAMs! Memory access times are not the only difficulty encountered with the faster clock speeds. In a similar vein, the design of an efficient 12.5 MHz system is more difficult than that of a 10 MHz system, since more careful attention must be paid to tP75$CRNG$CRNG$CRNG$CRNGBCRNG=CAMG@BODY330Pff`c0ΪT* f >>x>f 300<<331T@`g( T P2 |>|>|>d&`3  0> RKAUUUjpUkQT* afG3L Lc3 0|\|x#0 ?ZZTVTX* Ԧp<=agY `X!8'p??

(*READYSOFT) Hyper card runs (NY*JIM) Visual Conferencing, what ACO was based on (CMI*BILL) Yes you do, John. That jumper enables/disables DF1:. (DR*GLENN) amicus..there was something you had to fix in the back- ...jumper or dip swirch (ANDROID) oh yeah, Red Ryder. Heard some good stuff about that one (J. WOLF) Ready, what about using MAC add on hardware? (AMICUS) And scavenged standoffs and screws from the junk box... (*READYSOFT) yes all of (%Rrw3 megs usuable (CMI*BILL) Remember that you have to configure the second drive as device 1 rather than 0. (CBM*HARV) Readysoft...sounds great. Sign me up. [waving money] (*BUD*H) Will it use my Apple ImageWriter II? (*READYSOFT) no Mac add-on hardware (AMIGA*BOB) Yep Bill...otherwise you got bad juju (OJS566) Thats extraordinary!! (DR*GLENN) ah yeah it was the jumper..it has to be moved over or something (*READYSOFT) Will work with Imagewriter II (DEMO(&**D) What system resources in the amiga will the AMAX support? (J.

(*READYSOFT) we use WCS in A1000 (AMICUS) Readysoft, what is the official explanation for buyers, as to how to get the system software and ROMs? (CMI*BILL) J301 is the one you install the jumper on for DF1: supprt. You have to change your device number to 1 though. (J. WOLF) Good. I don't want the 64K roms. I want the 128k roms. (*READYSOFT) will work with laserwriter in serial mode (UK JEZ) readysoft: support for 256k roms is surely quite important, since all ma()/cs come with it nowadays dont they!? (CRYO) nite grog (AMICUS) Bill, you remember where J301 is located? (CMI*BILL) There should be a set of jumpers on the drive for device 0, 1, 2, 3 support. (-NOMAD-) what's the hardware setup for a2000/a1000 i have one of each (DJJAMES) AMICUS - under gray disk ribbon cable (AMICUS) Ah, didn't realize that about the drive. I'll look... (CBM*HARV) BEFORE THE CROWD THINS OUT I WANT TO THANK READYSOFT FOR TAKING THE TIME TO COME HERE TONITE AND CHAT(*Y WITH US. (*READYSOFT) if you own mac system/finder, transfer them, else buy them from Apple and transfer them. (CMI*BILL) Right beside the disk drive cable on the motherboard. (TOM H) Yes thanks!

(CBM*HARV) OKAY I HAVE A QUESTION.. FOR THE BENEFIT OF READYSOFT, HOW MANY OF YOU ARE DEFINITELY/PERHAPS/MAYBE/NOT INTERESTED IN BUYING AMAX WHEN IT IS RELEASED (AMIGA*BOB) Yes (DJJAMES) i have my roms already (ANDROID) I have heard (֭the using the old chipset will only give you a 128k mac but the new chipset will do a 1meg Mac +.What new Chipset?me (CRYO) ReadySoft: Does Amax use the Amiga Cust. chips for drawing or your own routines? (ALLEN M) I will (DR*GLENN) maybe (SLEEZYCZ) Very much so! (NY*JIM) <---- quite interested (OES928) I will as soon as it available (TERRY R) Readysoft: would it be possible for you to upload complete specs for AMAX to the library here. It wou(9ld help a lot. thanks. (-NOMAD-) sounds ok (CMI*BILL) probably. (RON K) Will you accept direct orders? If so address and order info puhleeze! GA (GROGERS) FlashBack question: how long does a backup < 20 Meg > take and whats the error correction? (JIM*M) I will (CRYO) < will get one for development. (DULNERD) maybe (TOM H) Yes, with more info (ANDROID) me (LUGNUTS) Mega Interested ! (DEMO*D) What system resources in the amiga will the AMAX support? (ȉ@(PROF. HAWK) i will by one for my business (TERRY R) definitely want some (*BUD*H) I want one yesterday! Love Amiga but some MAC stuff is great! (J. WOLF) I will be buying an A-MAX. (NY*JIM) ReadySoft - What was the most insurmountable problem you overcame? (J. WOLF) That is once I get the 128K roms and I may know where to get tehm. (AMICUS) I guess it wasn't insurmountable then, was it? :-> (UK JEZ) readysoft: why could u not read more than 34% of the mac disk on an Amiga!? my ti(ԏmings report suggests u can read nearly all of it, through the use of software quantisation of the bitstream. (ANDROID) Wheew! Now THAT's FEEDBACK!!! (-NOMAD-) a late comer<--- what resolution does it use, will flicker fixer work if hires, and does ready sell the roms (NY*JIM) I said it that way on purpose, John :-> (J. WOLF) Nomad, a Flicker Fixer will work. (*BUD*H) What does Apple think about it? They seem pretty selfish with their mac sturr (*READYSOFT) you can have any amount( of memory with the old chip set. (OES928) doea max have any problems now trhat will delay feb. shipment? (AMICUS) Wow, the AMAX will add a whole new dimension to Amiga piracy! :-> (-NOMAD-) good ques bud, is it legal or will we all get sued along with hp (J. WOLF) Readysoft, when's Apple gonna sue you? 8-} (AMIGA*BOB) Starting with the operating system John... (*READYSOFT) Central Coast has fooled around with reading MAC disks on amiga drives with limited success... (*BUD*H) Can th(ey sue if you don't provide the Rom (DEMO*D) Amicus,...That's what I was thinkin! (*READYSOFT) we may investigate furher in future. (J. WOLF) Jez, why don't you write a MAC-2-AMIGA conversion program to prove that it can be done? (*READYSOFT) Thing are looking good for Feb. Finalizing packaging- /production details. (AMICUS) Central Cost's PR said they'll have a drive on April 1. (CBM*HARV) jez... you could have it finished by what, tomorrow? (NY*JIM) 2 weeks, Harv (*READYSOFT) jez,(a send us some code. (UK JEZ) j wolf- its tempting... but ive got a lot of other unfinished projects that i oughta try and finish first! i think george chanm- berlain was workoing on one wasnt he!? (DJJAMES) so...where do we get MAc boot disks? (NY*JIM) From work, Dan. :-> (DEMO*D) ReadySoft...how bout som FastBack info? (TOM H) *READY, I am intersted in some MAC software for electronic design. I am concerned about reliability, compatability, and any problems with copy protections (_adevices required wit some software packages. (AMICUS) Yeah, right, DJ. Sounds like piracy city. (CBM*HARV) good question DJ...can one just go out and buy Mac system software like the Enhancer and MS Dos?? (*READYSOFT) mac system and finder can be tranferred from Mac diusks. (-NOMAD-) will it let me hook up to appletalk??? (AMICUS) Oh, it's an emulator, it's not piracy. I Forgot. It's just like the Transformer! (*READYSOFT) FLASHBACK not fastback (SILVERLOCK) Now we need a Lattice ( ECross compilier ! (J. WOLF) Ya, but how do we get the MAC system & finder without pirating the stuff? (GROGERS) Flashback, HOW FAST? (DEMO*D) sorry (*BUD*H) WIll it emulate a MAC emulating an Apple II? Just won- dering... That would look pretty neat. (CRYO) I WANT LIGHTSPEED C!! ;-> (*READYSOFT) It's much better than the transformer. FULL SPEED. (AMICUS) Wolf, it doesn't sound like you have any moral or physical obstacles in your way... (ANDROID) INFO#24 p 80: Mac Emulator costs $15( r~d how much testing have your done. (*READYSOFT) Hyper seems to run very well but not yet extensively tested. (OES928) What emulation does it do ? macPlus mac se macii? ga (*READYSOFT) We take 64K and 128K ROMs. This determines what machine you get. Other ROMs may be later supported. (*HARRY) How fast is AMAX compared to a Mac+ and what are the re quirements for the 3Meg model ( 飻 you mentioned <1Meg fat ag nus..what else?> (*READYSOFT) AMAX runs a little faster than a Mac PLUS.....Just a regular A2000 with 2-meg card. Any mem is now supported as well. (DEMO*D) will the AMAX run on '020ed amiga? Any thinking on a NuBus adapter? (*READYSOFT) The 68020 requires the 128K ROms. Apple bugs in the 64's mean they won't work in 32 bits....No thoughts on NuBus as yet. (DR*GLE( J6NN) how compatible are we ...could i run a mac arcade game...is the amy mouse supported? (*READYSOFT) We have run Megaroids, Loderunner. Mac games pale compared to Amiga anyway.... often copy protected which causes problems with Amax. The Amiga mouse emulates the Mac's; no problems. (UK JEZ) readysoft... is A-max code in any way related to Dave Small's stuff?... also, Can Amax read mac format disks with no extra ( disk drives...? if not, why not? (*READYSOFT) No completely independent of Data Pacific/DSmall....We can read only 34% of a Mac disk in an Amiga drive.....because of the multispeed format that the Mac uses our cart. has a connector for a 800K mac drive which gives full disk compat ..... YOU OWE US A STAR GLIDER II . (UK JEZ) thanx readysoft... my specs in f(cqront of me say the mac bit density stretches from 1.3 microsecs, to 2.0... sounds like its feasible to read more than 34% on an Amiga! indeed i do! (J. WOLF) How much is A-MAX? Do you guys supply or know where we can get 128K roms? How is the screen proportions?...How does A-MAX run with a Processor Accelerator at 14mhz? ga (*READYSOFT) Approx $150....We wont supply roms, but Computer Shopper has listings. Under inv(oi;estigation are other sources .....Screen proportions are good in interlaced or 640 by 400 mode. We have several screen formats incl. a 512 by 342, for full video compat....we also support the A2024 in 1008 by 800 line mode and the new chip set which gives 640 by 400 non interlaced. (RON K) Can AMAX support a SCSI hard drive instead of floppy? Will my external drive...attach to it and be readily(µN accessible? ...also will it work with all amy models or is it a 2000 card (*READYSOFT) Hard disk support will not be in first realease. All amiga drives can be used.....AMAx works with ALL Amiga mod els.....the amiga drives use a special AMAX format under the Mac the format used is runs much faster under the Mac OS then Amigdos would . (TERRY R) for those of us who are going to call (ɧC;our dealers on monday to place early orders what will your upgrade policy be when newer..and better releases come out. Is there a trade in policy> we need at least 4 units NOW !!! (*READYSOFT) Registration cards are supplied. You will be notified of upgrades for reduced cost. (SRU249) WILL IT DO COLOR WILL IT WORK ON A-500 ? GA (*READYSOFT) Works on ALL amigas.....Macs other than Mac II's are mono, so we can only (ąVuse 2 colours at any time. GA (PROF. HAWK) It will allow for full multitasking with the AMIGA right? Also physically, how big is it? (*READYSOFT) Sorry, multitaksing won't be in the first release < we have future thoughts for this tho> the cart is 2 inches by 4 inches with a cable to connect to the drive port to the cart. (CRYO) PA ? not answered (CBM*HARV) DOES AMAX WORK WITH THE CMI PROCESS ACCELLERATOR (*READYSOFT) p(Ŋ;Orobably. send us one and we'll find out. GA (*HARRY) Without any hard disk support, what would you consider a acceptable Mac setup to run lets say PageMaker . On the Amiga that is. (*READYSOFT) We run Pagemaker 1.2 on just about any system....eg. 1 meg a500/a2000 or 512k a1000. GA (SLEEZYCZ) This question may have already been asked but I got here late. Does AMAX use amiga drives? And do you recommend (N particular MAC roms over others? and what do you think the price will be? GA (*READYSOFT) yes, with a custom format....we can use 64K or 128K roms...128's are better....price:$150 tentativley for AMax (*REK) do you lose use of your current external disk with the card in place ... (*READYSOFT) no we have pass thru for ext drives; all of which may be used with Amax.

The highest current rating I can find for a standard quad NAND driver chip is 60ma, and 180ma is required here. My solution -- use an ordinary 74LS00 quad NAND gate and a 74LS04 hex inverter for the logic functions required, and discrete transistors for the current handling (hey, this is a homebrew project, right?). Three IC's, four 2N22222 general purpose NPN transistors (or one MPQ2222 quad-NPN transistor array), and a few random resistors is all il#Jt takes to handle two disk drives. My circuit is built to handle two drives, all in one package. Since 23-pin D connectors are hard to find right now, I made the design assumption that my expansion drives are always the last on the daisy-chain, i.e. I don't have to find a DB23S for another disk to plug into. DB23P (male) connectors are easily made from 25-pin connectors: with pin-insertion types, just don't insert the two pins at one end (13 anld 25); with solder-type or IDC connectors, snip off those two pins. Carefully "mash" the now-empty end of the shell so that it clears the standoff/tie-down studs. You may need a connector or two to practice on... BEWARE that the pins formerly numbered 14-24 are now pins 13-23! A description of the circuit follows (it's not easy to represent a schematic diagram with a character display; a schematic drawn with Deluxe Paint and stored in Il0FF format has been drawn by Thad Floryan, and is included with this document as "AddSch.iff-H". It may be displayed on the screen with the "ShowALL" program, and may also be printed with Deluxe Paint. This verbal description should be easily understood by techies -- draw it out! Hard-copy schematic diagrams are also available from me by mail; send a SASE and wait -- drawing it is faster! I hope to lay out a PC board for this, it's pretty simple, but hal5ven't yet, and my unit is wire-wrapped. If there is interest, I may be convinced to make such an item available at reasonable cost... DB23P pin 8 (MTRXD*) goes to the D inputs of the latch (pins 2 and 11 of the 74LS74), with a 4.7K pullup to VCC. Latch presets (pins 4 and 10) are pulled high (disabled). I also pulled the latch clear inputs high (pins 1 and 13); as mentioned earlier, you may want to tie these to the DRElxgSB* (pin 10) signal so the latches get cleared any time the Amiga is reset. DB23P pin 21 (SEL1B*) goes through an inverter (pin 1), the output of which (pin 2) goes to the latch clock (pin 3) and one input of a NAND gate (pin 1). The other input of that NAND gate (pin 2) comes from the Q (non-inverting) output of the latch (pin 5). The output (pin 3) goes to another inverter (74LS04 pin 3), thence (l5_pin 4) to the 10K series base resistor of a 2N2222 NPN driver transistor (pin 2 of an MPQ2222). The emitter (pin 3) is tied to ground, the collector (pin 1) goes to the RDY* line of the disk drive (pin 34 of the 34-pin connector). The Q* (inverting) output of the latch (pin 4) goes to the series base resistor of a second NPN driver transistor, whose emitter is also tied to ground, and whose collector goes to the MTR0lID* and LED* drive signals, pins 4 and 16 on the 34-pin connector. An analogous circuit takes care of the second drive, using the other half of the 74LS74, another NAND gate, two more inverters, and two more transistors in the MPQ2222 array. That's it! Be sure to pull up all unused inputs, as well as logic inputs taken directly from the daisy-chain connector. If you find and use a suitable open-collector NAND gate, and use spl1are NAND gates as inverters, be careful to use pullups when feeding that OC output to another logic input (and let me know what part you used!). NOTE that each floppy drive takes about 25K bytes of memory for track buffering and other overhead; you may find that you can't always afford the 50K for these additional two drives. There may be a software way to tell the Exec to add or delete the drives without rebooting, but I don't know it yet. If youl0`y build an expansion floppy unit for yourself, please let me know about it [using "mail eblack" on the WELL, or send mail via UUCP to {sun,pyramid,hplabs,amdcad}!chronon!eric]. Conversely, if you would be interested in obtaining a small PC board with the necessary interface circuitry (maybe even cables and connectors, who knows?), let me know that. Eric Black P. O. Box 118 La Honda, CA 94020 Special thanks to Rick Frazier (now mips!rick)l̟ for helping sort all this out! Having more floppy drives sure does cut down on disk swapping, but I've found that 512K is not enough (what an understatement!), and am constructing an expansion memory unit for myself. Initial plans are to ignore the auto-config protocol (Kickstart 1.1 doesn't do that, anyway), and just put a suitable command in :s/Startup-Sequence to tell Exec about the additional memory; eventually it will auto-config.

If you look in the hardware manual (preliminary) you may think the connector looks like: 123.........................43 ............................86 This is WRONG. If you cannot find an 86 pin connector with .1in spacing (sometimes called a 43 pin dual row connector) you can cut down a longer connector. I easily found 100 pin connectors. If yoI\ou do this be careful when installing the board that the connector is aligned with the cardedge in the Amiga. It is very easy to have it slip to the side with one end missing. This will harm the computer. When looking at the chips from the back side (as viewed above) the pins are like this: 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 For 16 pin chips. For other sizes of chip, the numbering goes clockwise as shown. All chip sockets, except the 24 pin socket for I uthe MC146818, have a .1uf capacitor connected between the corner pins 8 and 16 (or 7 and 14 or 10 and 20). There are two techniques that I find convenient. If the type of socket and the type of capacitor permit, the nicest thing to do is to attach the capacitor to the socket pins before the socket is pushed into the board. The socket may permit the capacitor to fit into the cavity usually found between the rows of pins. The wires will raise the socket only slightly off the board. If I  this won't work because of the parts at hand, I usually solder the capacitors on last, after all wirewrap connections are made. Any other approach tends to make wirewrapping difficult because the capacitor is in the way. I would wrap the power and ground connections first. Make a grid of these wires such that each ground pin is connected to its nearest neighbors in all four directions. If your sockets won't accept four levels of wrap, connect at least three ways so that as much of tI {t|xhe grid structure as possible is maintained. The memory array has many pins that are common to all 32 chips. These connections are also best made with a grid like pattern. The idea is to connect all the relevant pins with a minimum of inductance. Since, with wire wrap, there is no other parameter under your control, redundant connections are the way to achieve this. The other connections can be made in any order you like. Minimizing total wire lengths when connecting several pins isI d nice, but not strictly necessary. I made some effort in this direction when I placed the parts and wired them, but the layout is not optimal in this sense. I don't think it is necessary to be too concerned with the wirewrapping "rules" for this board. One thing to attempt to do is to keep wires on the same "level". If you have four pins (for instance) you connect the first and second, then the third and fourth, and finally the second and third. Doing things this way means that when I O6you make a mistake you only have to remove at most three wires to correct it. You cannot unwrap a wire and re-use it, (if you do, the connection will probably fail in a few months) so any misconnected wire must be completely removed. This means any wire covering it must be removed. Don't daisychain yourself into a situation where many wires must be removed to correct an error. There is a variable capacitor in the clock circuit. This is used to adjust the clock so that it keeps propILer time. The capacitor should be mounted so that it can be adjusted with the board installed and running. Since there are many styles of capacitor, I cannot suggest any particular method. too concerned with the wirewrapping "rules" for this board. One thing to attempt to do is to keep wires on the same "level". If you have four pins (for instance) you connect the first and second, then the third and fourth, and finally the second and third.

Next is the connector for the Amiga. Three rows below the connector are used for timing logic and the clock. The chips all face the Amiga so that the wire wrap pins of the chips and the connector face out for easy testing. (I hope this isn't an issue for you, but I did a lot of it.) The connector is spaced away from the board by placing a 1/2 inch wide strip of plastic (made from the tubes that wire wrap sockets come in) between the rows of pI#rށins. This leaves just enough room on the pin on the back side of the board for one wire to be wrapped on the pin. This allows the connector to reach into the Amiga and leave room for the chips between the board and the side of the computer.

If a graphics object is a program constant, the program must be chip memory resident. There is no way to do this within a language. When a program allocates memory, it must specially ask for chip memory if needed because the operating system will allocate >from external memory if it can. If you want to use one of the programs that does not work with external memory, simply do not use the AddMem command. There is no need to remove the card. Amiga has released the ATOM program+f to developers which is used to tell the loader that some hunks must be loaded into chip memory. If you can get this program, it will fix the above problems. The hardware clock isn't used by the Amiga during normal operation since it keeps its own internal clock. I have written a program to read the hardware clock and set the system clock (this is more trouble than I wanted). This program is also included in this release. The easiest way to use these new resources is to modify your, s/startup-sequence file to include: AddMem 400000 500000 Clock as added commands at the beginning. I also usually copy the entire system disk to ram: and reassign all the logicals to the copy in ram:. The system is very fast when running entirely out of ram. I wirewrapped the memory since I expected to make changes. It took three tries before the control circuit worked well. There were a number of pins that were essentially undocumented and I had little choice but to try things  -0Sauntil they worked. Because this design has no support from Amiga, I cannot guarantee that it works with your machine. On the other hand, I design memories (and other things) for a living. I know what I'm doing. The design is very forgiving of small timing changes (another reason to keep it slow) and I do not expect anyone to have problems. I have no intention of supplying a PC board. I don't mind if someone else takes on that project as long as it is non-commercial. (If you are inter .P%9ested in a commercial design let me know, I would do many things differently if it were a high quantity commercial product. This design is bent in the direction of ease of duplication with no special parts.) There are four additional files I will mention here. The mechanical description is in mem.mechanical. This includes the connector and board info and the chip socket locations. Some comments on construction are also included. The parts list is in mem.parts. The parts given will w *ork. Substitutions are possible, but at your own risk. The schematic is in mem.schematic and clock.schematic (this section can be built at a later time.) This is not the most beautiful method of drawing schematics, but it allows this project to be electronically documented so it can reach a lot of people without the 10th generation xerox problem. The schematic files look best if printed at eight lines per inch. re essentially undocumented and I had little choice but to try things 0Y---+ +----- GND | + 13 | | 7 6 | | --------- D2---------+ +---------------+ | ------- 4 CELL 12 | | 8 5 | | --------- NICAD D1---------+ +---------------+ | ------- 11 | | 9 4 | | --------- 5 VOLTS D0---------+ +---------------+ | ------- | | 1 ˫) | | | 19 | | 1 15 | | 13 | SEL*------O| +-------+-------+ |O-----------+ GND +-----+ | +---------+ | BRW ---------------------+ | +-------)-------+ 74LS04 [A6] O | | 3 |\ 4 SEL 1 12 +-----+ 9 | |l% SEL*----| >O-------+ GND-----+ +----+ | |/ 2 +--- | | | LDS----------------+ \ 6 11 |\ 10 AS 11| | 8 | 4 | |O------| >O--------|> |O---+ | A1-----------------+ / |/ +-----+ | | 1 |\ 2 5 +--- O | | BRW-----| >O-------+ | | | |/ 3: +-------/\/\/-----+--------+ MC14 | B +---)|--N | / 390k 17 | 6818 | B | 1uf D | \ 560 DS---------+ | | +--+ / 14 | [C8] | +--|<|--+ | | AS---------+ | | | | [10] 18 +-----+ 2 11 | | +-/\/\/-+ | 12v D7---------+ +---------------+ | 100k/ | | 17 |74LS | 3 10 | | 18 | | D6---------+ 245 +---------------+ +------+-----+ | 16 | | 4 9 | | 22 | G | D5---------+ +---------------+ +------+--)|---N | 15 |[B8] | 5 8 | | 1uf D | D4---------+ +---------------+ | | 14 | | 6 7 | | 20 | D3---------+ +------------5?

The clock is a Motorola MC146818. It keeps track of the date and time including daylight savings and leapyear. A nicad battery is charged by the Amiga when it is powered up. This battery runs the clock when the Amiga is off. As long as the Amiga is on 1% of the time, the clock will remain accurate. This memory board does not autoconfigure. This means that the Amiga doesn't know about it until it is told. A program called AddMem is dist)JKributed on the assembler or C disks. This program is needed to tell the Amiga that the memory exists. I have not written a clone of this program. I have written a memory test program to test the board. It is included in this release. At this time, a number of programs, including Deluxe Paint, do not work properly with external memory. I hope that as more Amigas get added memory the suppliers of these programs will fix the problems. Mostly, graphics objects cannot reside in external t@1*R ................ P2 ......... 50 PIN MEMORY CONNECTOR .............. P3 ......... 60 PIN NOTE: DO NOT INSTALL U4,U5,U6,U7,U8 AT THIS TIME. If you want to wire it, go ahead the DRAM will be comming soon! CIRCUIT DESCRIPTION The reason for the 74LS688 (8 bit comparitor) is to allow for upgrading the board for AUTOCONFIG'ing. I don't plan to do this until I get the important work done (DRAM & CLOCK). It is not hard to use this way, you have to "install" the board anyway. TtA6he advantage of AUTOCONFIG is that the AMIGA decides where in the memory the board resides. This is not a problem since it is the only board in the system..... The PAL (Z5) is used to control the DRAM. It is not needed at this point so don"t worry about it. The 'LS139 is used to decode addresses intofour 16K blocks. 1: $800000 is the NCR53C80 2: $801000 is the PSEUDO DMA 3: $802000 is for the CLOCK (not done yet) 4: $803000 is not used at this point It may seem like altBot of wasted memory but the AMIGA can only AUTOCONFIG in 64K blocks. The second half of the 'LS139 is used to convert the R/W signal of the 680x0 to the read & write lines used by the NCR53C80. Z4 -the 7406 will be used as the interrupt driver. I want to use INT2* for the NCR's interrupts and INT6* for the DRQ*. DON'T install the 7406 untill the real driver is available. Your AMIGA won't like getting interrupted by the NCR53C80! That is all there is to the SCSI interface. (t CAtleast for now) It is possible to add DMA capibilities to the board but lets get the thing up and running first! READING THE "NET-LIST" The schematic "AMSCSI" was made on an IBM XT using Future-Net software. I wish that someone had a good schmatic capture pgm for the AMIGA ! Anyway to wire a board from the "net-list" ignore the "Path Ref" & the "Symbol Ref" cols.

EASY ISN'T IT. It is recommended that the SCSI bus be terminated with 220 ohm / 330 ohm resistors. These are not included on the "net-list". Every SCSI signal should have a 220 ohm resistor to +5v, and a 330 ohm resistor to gnd. You might want to try it without the terminators, but leave room for them just to be safe.......... When I get a chance I will make a schematic on Dpaint. I have included two BASIC programt Grs that will help you test your board. 1: SCSIMon - a small monitor that constantly reads the NCR53C80 and desplays the reg.s in HEX 2: SCSIdvr - a very crude program that "PEEKS & POKES" the SCSI . With it you can FORMAT, READ, & WRITE a hard disk. It takes about 10-20 sec to read, or write 1 sector !! ( Not blazing speed is it?)

This board plugs into the expansion port! That port is directly connected to the CPU and other chips in your AMIGA. Care must be taken so as not to short anything to +5v or gnd as that may DESTROY your AMIGA. The circuit and design concepts are sound, but YOU are in control of your machines destiny. This project is NOT for the casual hacker. REMEMBER, Don't yell at me if you break your machine!!! On the lighter side, my board worked the first time it was turnetTid on. It must be easy if I didn't make any errors... Just take your time and all will be OK ! After deciding where to locate all of the parts, use the "net-list" to wire it. I suggest doing all of the wiring to the board before installing the IC's. Remember that the NCR53C80 is sensitive to static, so be careful. Also before installing IC's it is a good practice to check the power and gruond pins on all chip sockets. PARTS LIST PART# LOC t?N USE 74LS688 ....................... Z1 .........

The file Building is for those who are actually building the Lucas board. If you're just considering building one, a look through this file will let you know what you're getting into and what you can expect to get out of it. The #?.draw files have the two drawings which comprise the LUCAS board. They were done using draw plu8&# Cs, and they are included here in case you wish to make plots or printouts of your own. You'll have to join the similar draw1 and draw2 files together to get a complete draw file (they were split for Usenet transmission). The #?_List files are the PCAD document files. The Net Lists will help in debugging. The #?.pld files are the four PAL equations for the pals on the LUCAS Board. If you've decided that you would like to build a Lucas Board here's where and how much.

Several people wanted it so here it is... Two notes: 1. It's a generic 4 parallel port SCSI host adapter device driver. Those of you with a yen to hack TTL gates could cook up an interface for $20 - $30 to use with this driver. 2. It includes notes on making a DF1: partition for use with DiskCopy...

If you want blindingly fast floating point the best way is to recompile your code so that it uses direct inline F instructions. I am making available on the Transactor Disks two programs called Mandslow and Mandfast. They are slight adaptations of RJ's original mandelbrot program, adapted by Eric Haberfellner. These two programs are the same except that mandslo)20-w was compiled for standard Amiga while mandfast was compiled to use inline F instructions. As an example a moderately deep mandelbrot which runs in 1 hr. 20 min. on a standard Amiga runs in 4 min. 20 sec. with the LUCAS board installed. Compatibility The LUCAS board works with all the expansion boards I have but I'm sure there will be some out there that will bomb out. I will keep a list of those that do and those that don't and post it regularly on Usenet and BIX. The ones I have* are the Comspec 20 Meg. Hard Disk, Comspec 2 Meg. Memory board, EASYL, and the Micobotics Starboard 2 Meg. Memory board. As a matter of interest only, the board works fairly well at 20 MHz but periodically bombs. I have only 16 MHz parts; when I debug the bomb it seems to be the fault of the on-chip instruction cache. If you have 20 MHz parts, try it and let me know. Even if you have 16 MHz parts its worth the price of a 20 MHz crystal to see if it will work. Who knows? You might g+ et lucky. Conclusion The performance of the Amiga 1000 with the LUCAS board intalled will be improved, but it won't perform miracles. For general purpose computing I find that compiles are only about 1.4 times faster, hardly worth the trouble. However, any program which uses Floating point will be improved considerably, and those which have embedded F instructions will indeed appear miraculous. On the other hand, the board does allow for 32-bit wide expansion memory, and if install, 'ed you can expect considerable general purpose performance improvements as well. I plan to design two boards: one with standard 100 or 120 ns. DRAMs and a second with some high speed Static Ram for no wait state operation at 16 MHz. You get most of the performance increase by having the memory 32 bits wide, but I can't resist seeing how fast it will go with no wait states at 16 MHz.

And sync back up with the 16 MHz 68020 when we do finally issue a *DSACK1. Confused? Wait! It gets better. Most dynamic memory boards when connected to the Amiga expansion bus will assert XRDY to hold off the assertion of *DTACK while they do a refresh cycle instruction. On the 68000 this is a user mode instruction; on the &mE68020 (and 68010 and later parts) it is a supervisor mode only instruction, i.e., if its executed on a 68020 in an Amiga you get a privelige violation guru. If you're writing software, don't use this instruction; use instead the GetCC() library function which translates to a MOVE CC on the 68020, which is a valid user mode instruction. This function translates to a MOVE SR if there is a 68000 in the Amiga. This way you're safe both ways. If you're one of those people who t'<:hought encoding information in the upper 8 bits of the address field was a nifty idea ... Oh well, time to learn the error of your ways. Of course if you use any instructions from the 68020 super set then this code will never run on a standard Amiga. For further information see section 21 of the Washington Amiga Developer Conference Notes, "Software Issues in 32-bit Amiga Systems" by Dave Haynie. The new release of 1.3 has new IEEE Double Precision Math Libraies which take advantag^ by some peripheral device. The 68020 works much the same way except there are two *DTACK-like signals, *DSACK0 and *DSACK1. Because the 68020 can address in bytes (8 bits), words (16 bits) and longwords (32 bits) it must be able to differentiate between them. It does this by use of its dynamic bus sizing capability. A peripheral responds to a bus cycle by asserting one or both of the *DSACKx signals which tells the 020 the size of the transfer. DSACK0 DSACK1 TRANSF7eER SIZE 0 0 32 bit transfer 1 0 16 bit transfer 0 1 8 bit transfer 1 1 Insert Wait States Bus cycles on for the Amiga are always 16 bits wide so we will assert only *DSACK1 when responding to Amiga cycles. When we are running cycles for the 68881 (FPU) or 32-bit wide ram on the LUCAS board expansion connector we must assert the appropriate *DSACKx combination. In general ter 2ms with no wait states the 68000 will run a bus cycle in 4 clock cycles; the 020, however, will run the same bus cycle in 3 clock cycles. To correct this we must delay *AS and *DS (Data Strobe) from reaching the Amiga until after the rising edge of the S2 phase of the 7.16 Meg. CPU clock. This is accomplished by the flip-flops U8a and U8b: inverting *AS from the 020 and using the complementary output with the flip-flop's reset tied to the inverted *AS will delay *AS the desired amoun"b^t and terminate *AS20DLY when the *AS from the 020 terminates. This same technique is used for *DS. This creates the two timing signals *AS20DLY and *DS20DLY. Byte addressability on the 68000 is accomplished by the Upper Data Strobe (*UDS) and the Lower Data Strobe (*LDS). The 020 has only a single Data Strobe (*DS). It uses a combination of the two SIZE pins and A0 and A1 to define the tranfer pattern from the 020's internal multiplexer to the external data bus. (Note: bytes appear< on data bits 24-31, words appear on data bits 16-31). It is therefore necessary for us to create *UDS and *LDS. This is accomplished by the following PAL equations. Note: The data strobes are not asserted during a Coprocessor cycle. (CPCS) !UDS = (!DS20DLY) & (!A0) & (CPCS) !LDS = (!DS20DLY) & ( SIZ1) & (CPCS) (!DS20DLY) & (!SIZ0) & (CPCS) (!DS20DLY) & ( A0 ) & (CPCS) The 68000 contains logic to support the 6800 family of products, and the Amiga uses this to inteGarface to the 8250s. We must also emulate this interface as it is not present on the 020. A secondary clock called the E clock must be generated. It has a frequency of 1/10th the CPU clock and has a duty cycle of 60% low and 40% high. This is done by a decade counter in PAL U4. When running a 6800 family cycle the Amiga or peripheral generates a Valid peripheral Address signal (*VPA). The 68000 then syncs itself with the E clock and issues a Valid Memory Address (*VMA) and ends the cy>cle on the falling edge of the E clock. The equation, !Z3 = !QD # QC # QB # QA ; on PAL U4 in combination with the equation !Z1.D = (DS20DLY) & (!Z1) # (DS20DLY) & ( Z3) & (!VMA); asserts *DSACK1 in the 9th state of E clock by the generation of the Z1 signal so that the long VPA, VMA cycle can be terminated correctly. 68020 to 68881 Interface The MC68881 chip select (*CS) must be decoded from the 020. The 020 generates a 111 on the Function Code pins (CPU Sp&mace), a 0010 on the address lines A16-A19 which means this is a FPU coprocessor cycle, and a coprocessor ID on Address lines A13-A15. Since there is only one coprocessor in this design, A13-A15 are undecoded. The rest is decoded by PAL U4 in the following equation: CPCS = (FC2)&(FC1)&FC0)&(!A19)&(!A18)&(A17)&(!A16) This generates the *CS (Chip Select) to the 68881. Zen and the Art of Cycle Termination (An Asynchronous Synchronous Asynchronicity.) The generation of the *DSACK1 signal from the Amiga *DTACK caused me at times to doubt not only my own sanity but that of the universe itself. The *DTACK signal from the Amiga should appear and be sampled during the S4 phase of the clock cycle. Unfortunately it doesn't quite know that. It responds more or less correctly when it is talking to internal ram but when external (FAST) ram is accessed *DTACK comes back almost right away. Remember that *DTACK is the only way we have of determining the length of a cycle. We•> will cope with this anomaly in a moment. Since the 020 is operating at 16 MHz - i.e., quite asynchronous to the Amiga clock - you have to sync up somewhere along the line with the Amiga 7.16 MHz clock. The ideal place to do this is when the two Amiga clocks C1 and C3 are in the condition C1 high and C3 low. These signals are not available at the processor and for a long time I had these two lines coming up off the motherboard. However the 7.16 MHz clock that is available at the proCcessor can produce a reasonable facsimile. I divide the 7.16 MHz clock by two using U9a then logically OR it with the original 7.16 MHz clock and this turns out to have the same timing as C1 high and C3 low (my faith in the universe began to rekindle at this point.) In the PAL equations this is DTPRELIM (DTack PRELIMinary). Now we have a reference point to sync back up with the Amiga.

One, seemingly operating at 7.16 MHz and synchronous to the special purpose chips responsible for the video, sound, etc. and two, a 16 megahetz asynchronous system between the 68020 and 68881 and any possible 32-bit wide memory connected to the LUCAS bus. The essential design criteria I used for the board were that it$.k should be able to run asyncronously to the Amiga clock (so speeds of 16 MHz or greater could be achieved) and that there be no connection other than through the 68000 socket (to simplify installation.) In order to achieve this the board must look like a 68000 (4 clock standard bus cycle) running at 7.16 MHz when it is running its bus cycles but when it is doing internal processing or talking to the MC68881 or future 32 bit wide expansion ram, it should run at the full 16 MHz (3 clo͝1wck bus cycle). 90% of the problem in making this board work comes down to the problem of making the 68020 appear exactly like the original 68000 it replaces as it has been used architecturally in the Amiga, but able to go like stink when it gets the chance. The address and data lines are easily implemented as they are connected directly from the 68020 to the 68000 socket. Note that the 16 data bits are connected to data bits D16 through D31. The upper eight address bits on the 6802qk0 are simply left unconnected. I have used the * convention to indicate low true signals for ease in typesetting the article, i.e., *AS means AS is a low true signal. The PAL equasions are written in CUPL format so I appologise to all you PALASM user's. 68020 to 68000 Interface. The 68000 has an asynchonous bus structure. It asserts Address Strobe (*AS) to begin a bus cycle then waits for the assertion of *DTACK to end the cycle. This is usually 4 or 6 cycles, but may be held off/FtOVE.B 29(A0),D1 CMPI.W #12,D1 ; In range?

So let's be * careful out there. ;) * * The MOUNT command can be used to partition the two hard disk drives into * smaller pieces. (See hints below) * * Here is a sample mountlist entry for a Seagate ST-4051: * DH0: Device = scottdisk.device * Unit = 0 * Flags = 1 * Surfaces = 5 * BlocksP/D؎erTrack = 17 * Reserved = 2 * Interleave = 0 * LowCyl = 0 ; HighCyl = 976 * Buffers = 30 * BufMemType = 0 * # * Don't forget that the numbers used in the mountlist and used at the end of * this driver DO NOT HAVE TO MATCH. HOWEVER, the total SIZE given in the * mountlist MUST NOT exceed the size encoded at the end of this driver. * * To setup a system for operation: * 1. Configure the driver for your hard disk drive(s). * 2. Co/Wnstruct this driver and place the result in df0:devs/scottdisk.device * 3. Insert entry(s) into df0:devs/mountlist * 4. For each drive: * A. mount * B. format drive name * C. Insert 'mount ' into your df0:s/startup-sequence * 5. Enjoy! :-) * * Hints: * If like me you hate using a slow 2nd floppy drive to copy disks, then setup * a partition on your hard disk using mountlist. Make it the same as an * amiga floppy: 11 sectors per track, /eR2 sides, 80 tracks. Then mount it and * you can diskcopy to/from a floppy to/from it! You can even call it DF1! :) * Rather than use the CLI AddBuffers command just tweak the 'Buffers =' line in * the mountlist entry. * * Please note that this driver could have tons of things done to it to improve * performance.

We have tried installing 25 Meg. parts and have had some limited success, but as of this time I've done little testing. If you have the parts please try it, and let me know how it goes. Although these higher speeds are possible the board was designed for operation at 16 Meg. so be adventureous at your own risk and expence. If you didn't buy the pa j\ll... so long, and thanks for all the fish. Once you get one of the bare boards and procure all the parts, next follow the enclosed instructions and carefully solder sockets for all the IC's and the crystal onto the board. Solder the resistor paks and the capacitors into place. Insert the 64 Pin header for the 68000 socket and solder it in. Installation is quite simple but should be carefully done. Remove the plastic cover and the EMI shield from the Amiga base unit. On the right h vﴼand side of the PCB, just beside the Exansion connector, is the 68000 CPU. Gently pry the 68000 out of its socket, and store it on a piece of styrofoam somewhere safe. Now insert the LUCAS board into the 68000 socket, being careful to insure that all 64 pins are correctly inserted into the socket. If you want to be real careful remove the disk drive so you can see better. Watch the ribbon cable for the internal disk drive as the bends in the cable can make things awkward.

evening or two. If you have problems then its up to your ingenuity to solve them. If you don't have some experience with a soldering iron, please, don't let this be your debut. I will gladly help anyone with problems. There are three ways you can get in touch with me, USENET at anakin@utcs.toronto.edu (Brad Fowles), BIX in the ANAKIN, AMIGA conference or by regular mail through Transactor. If you do manage get my p [Bhone number you better be able to sweet talk me within 30 seconds. I hope that if there is sufficient interest out there that local user groups or individuals will add their help to anyone having problems. I have no objections should anyone get the bare boards and put them together and install them for a modest price, but please remember that the purpose of this is to make these available to end users as cheaply as possible.

One, I wanted one myself and couldn't afford the commercial versions. Two, some friends of mine who are using SCULPT 3D and ANIMATE from Byte by Byte (both are available in 68020-68881 versions) needed more horsepower to render their images fast enough to actually make money at it. Three, I figured all of us Amiga 1000 owners out there with true hacker's hearts needed some light in our future since 1 meg. of chip ram ain't. (Maybe some of those 1000's out there can beL^come dedicated rendering machines.) When I started the design of this board I used as a reference an article from EDN January 9th 1986 pp216-219. While looking at this design I became aware of an application note from Motorola AN944/D, "MC68020 AND MC68881 PLATFORM BOARD FOR EVALUATION IN A 16 BIT SYSTEM". I recommend both these documents, especially the latter, if you wish a better understanding of how this board works. Unfortunately it is impossible within a short article such as " %Nthis one to give more than a brief overview of how the board works. I will try and highlight those aspects which are specific to the Amiga, but a thorough understanding will require some digging on your part. I also recommend the User's Manuals for the MC68020 and the MC68881 which are available from Motorola as "MC68020UM/AD" and "MC68881UM/AD" respectively. O.K. Here is the disclaimer.

The case drills cleanly and easily, so there is no need to force the drill (which might crack the case). Proceed now to solder wires to the jack per the wiring diagram. It's easier to wire the jack before fastening it to the case. Note the excessive slack in the wire which is necessary to provide working room when routing the wires when re-installing the RFI shield. Now install the jack i un the case and position, but do not fasten, the disk drive and interface PCB back in the case. Following the wiring diagram, connect the wires from J6 (the jack) to J3 (on the interface PCB) and to the disk drive power connector. You should buy or make connectors that will fit the pins (at J3 and on the disk drive); I re-used parts of the original cable assembly and also made one connector from a piece of 0.100" spaced socket material. You will need to be creative when fabricating v the new harness. Be sure to verify the +5 VDC and +12 VDC connect to the original pins on the disk drive. Also make sure that the ribbon cable to the disk drive from the interface is firmly connected, and proceed to reassemble the A1010 placing all screws in their original location. Check all wires to be sure there is adequate clearance and no inadvertant short circuits. Now wire the plug (P6) from the power supply, making sure the +5 VDC, +12 VDC and ground will mate with the pwi sHroper pins on jack J6; this plug is shown as P6B in the illustrations. The P6A is an accessory "jumper plug" which, if inserted in J6, powers the drive as it was originally wired. Before connecting the modified drive to your Amiga system, power it up stand-alone and verify the proper voltages are present. If so, then remove power and put the A1010 case cover back on. With your Amiga and the modified A1010 powered off, connect the DB-23 cable from the modified drive to the back ofx 4 DF1:, power up the system, and enjoy increased floppy disk capacity. Note that each additional A1010 drive connected to your system will consume an additional 25K of chip RAM for disk buffers; this "may" cause problems with some programs, so remove the drive if necessary.

Transactor magazine has graciously agreed to make available bare printed circuit boards for this project for $40.00, and the complete 4 PAL set for $30.00. The rest is readily available from local suppliers. The schematic is published here, as are the PAL equations. Anyone who wants the film plots or Net Lists so they can adapt the form factor to the Amiga 500 is welcome to them for whatever it costs me to get and ship them to you. (PCB design was done using P-Cad on J3er... an AT ( ...almost said the I word )). If you own an Amiga 1000 and you would like to experiment with a 68020 and 68881 combination to improve performance this may be the cheapest way to get there. Unfortunately the chip set is going to cost you about $370.00 Canadian. Our aim is to make the rest as cheap as possible. You should be able to be up and running for under $475.00, or about three quarters of that if you live in the real world. There are 3 reasons that I decided to d s5me to use); that was the only location that worked for me. Your connector may permit other placement. Experiment now, while all the parts are still in the case and before you drill any holes. Once you've found a place for the jack, mark the location on the outside of the case and remove all parts (disk drive, RFI shield, and interface PCB) from the case. Drill a small pilot hole for the jack at exactly the marked location, using, for example, a 1/16" bit.

The transfer software allows you to select which drive contains the disk you want to copy from (the source disk), and which drive contains the disk you want to transfer to (the destination disk). Note that you must format the destination disk first (if it has not already been formatted) from the WorkBench or CLI before loading The 64 Emulator. By default, the source device is set to 8 which will copy from the Commodore 64!ͮͨn serial disk drive, and the destination is set to 10 which will copy to the built-in Amiga 3-1/2" disk drive in Amiga Standard format. If you need to change the source device number press S, and if you need to change the destination device number, press D. Now select whether you want to make an exact copy of the disk or copy individual files by pressing E or F. If you select E, the copy will be more compatible with the 1541, but will be slower than Amiga Standard whe"fMen being accessed, and uses only 1/5 of the disk space available. The Amiga drive must be in the 1541 Emulation mode when making an exact copy. The copying will begin immediately. If you select F, you may copy using 1541 Emulation or preferably Amiga Standard on the 3-1/2" drive, which will increase speed and allow for all of the available disk space to be used. You will be asked for a directory pattern (you may simply hit RETURN on this option). The default pattern o#ϯ|f * will display the entire directory of the source disk when RETURN is pressed. To select a file to be copied, move the cursor to the file name and press the RETURN key (a Y will appear beside the name). Repeat this procedure until all the files that you want copied have a Y beside them. To begin the copy, press the F1 key. If the software you want to transfer is copy-protected, the transfer software may not copy it to 3-1/2" disk format. $Г|A LIMITATIONS Due to the nature of The 64 Emulator, some programs will run between two and five times slower than the Commodore 64, others will run at full speed. This slow-down will not be noticeable on all programs. Games that allow you to change the speed of play should be set at maximum speed to compensate. Due to hardware limitations on the Amiga, sprites may, from time to time, flicker or change color. This is most noticeable when many sprites are close to e%Ĕach other. Most protected software requires the Serial Interface and a 1541 disk drive to load the program. This is due to the copy-protection employed by various companies. Even with a Serial Interface cable, some software may not load with The 64 emulator if fast loaders are used as part of the protection. The 64 Emulator requires complete control of the Amiga hardware, and as such, multitasking is not allowed during the emulation.

Joysticks Many 64 programs require that a joystick be in a specific port (1 or 2). If a program appears not to be reading the joystick, first make sure the desired port is set to read joysticks and if this is the case, try setting the opposite port to read joysticks and connecting the joystick to the other port. Mouse The 64 Emulator allows you to select how the Amiga mouse is to be interpreted by the 64: as a 1350, as a 1351 or as paddles. { The default setting for the Amiga mouse is Paddles. Light Pen When using a light pen with The 64 Emulator, it must be plugged into Port 1. You must set the configuration for Port 1 to Joystick. 1764 RAM EXPANDER The 1764 RAM expander is a device that allows 256K of RAM to be added to a Commodore 64. If your Amiga contains at least 1 Megabyte of memory, the configuration editor will allow The 64 Emulator to simulate this device. By setting the option to ON, 2W56K of the Amiga's memory will be set aside to be accessed as if a 1764 cartridge was connected. MONOCHROME MODE The 64 Emulator spends a significant amount of time creating Amiga video image from the screens that the 64 specifies. This process is complicated by the variety of methods of generating color that are available on the 64. When the Monochrome mode is enabled, all text and high resolution images are adisplayed with only two colors - green and black, just lis0tke a monochrome monitor. For programs that are very screen intensive but where color is not essential, using the monochrome mode gives a noticeable speed increase. BORDER Due to hardware limitations of the Amiga, generating a border around the entire screen would greatly slow down The 64 Emulator. As an alternative, The 64 Emulator allows you to select a border at the top and bottom of the screen. The speed will not increase if the border is turned off, but it may mak'e the screen more attractive with some programs. ALTERNATE CHARACTER SET The Amiga displays a higher resolution than the Commodore 64. This option allows The 64 Emulator to use an alternate character set whose letters are clearer than the standard 64 character set. To select the alternate character set, change this option to ON. Click the option again to turn it off. BASIC COMMANDS The 64 Emulator allows all Commodore 64 BASIC commands:dH ABS, AND, ASC, ATN, CHR$, CLOSE, CLR, CMD, CONT, COS, DATA, DEF, DIM, END, EXP, FN, FOR, FRE, GET, GET#, GOSUB, GOTO, IF, INPUT, INPUT#, INT, LEFT#, LEN, LET, LIST, LOAD, LOG, MID$, NEW, NEXT, NOT, ON, OPEN, OR, PEEK, POKE, POS, PRINT, PRINT#, READ, REM, RESTORE, RETURN, RIGHT$, RND, RUN, SAVE, SGN, SIN, SPC, SQR, STATUS, STEP, STOP, STR$, SYS, TAB, TAN, THEN, TI, TI$, TO, USR, VAL, VERIFY, WAIT. This guide is not intended to be a reference for the above BASIC command݇0`s. A number of good books are available that outline how to use these commands. THE KEYBOARD As the Commodore 64 keyboard and the Amiga keyboard contain several different keys, The 64 Emulator changes the functions of several Amiga keys to correspond to keys that are required by the 64. The following table outlines the major changes: AMIGA KEYS PERFORMS FUNCTION OF: ESC RUN/S"TOP DEL RESTORE TAB CONTROL Left AMIGA COMMODORE Key F10 HOME Shift F10 CLR BACKSPACE DEL Shift BACKSPACE INST There are three Commodore 64 keys that perform no function unless pressed with another key, these are SHIFT, CONTROL and COMMODORE. SHIFT is used to access cě^$apital letters, graphic symbols and punctuation. CONTROL is used with the 0-9 keys to change colors and many programs use CONTROL with a letter to represent different functions. The COMMODORE key is used with the 0-9 keys to change color and with letters to generate alternate graphic symbols. The SHIFT and COMMODORE keys when held down together will toggle the screen between upper case/lower case and upper case/graphics. The RUN/STOP key (ESC on the Amiga) is used to shHtop execution of BASIC programs and loading files. If holding RUN/STOP does not stop the program, hold RUN/STOP while pressing the RESTORE (DEL on the Amiga) and BASIC should stop. If this fails, pressing CONTROL, LEFT-ALT, and HELP simultaneously should reset the 64 to BASIC, clearing the current program (as if the emulator had just been loaded). If this doesn't stop the program, you will have to reload The 64 Emulator. TRANSFER SOFTWARE |%I To make the transfer of software from 5-1/4" disks to 3-1/2" disks easier, ReadySoft Inc. has included a transfer program on The 64 Emulator program disk. To load the transfer program, type: LOAD"TRANSFER",10 RUN If you have changed your device number, replace the 10 in the loading command with the device number of the drive containing The 64 Emulator program disk. This drive must be set to Amiga Standard in the configuration editor so that g>zd drives and RAM: refers to a temporary file that is created in the RAM of the Amiga (RAM: requires at least 1 Megabyte of memory). The 64 Emulator is also compatible with the Amiga 5-1/4" drive (Model 1020) only in the AmigaDOS format. It will not read Commodore 64 disks directly on an Amiga 1020 drive. A Commodore 64 compatible drive (such as the 1541) and Readysoft Serial Interface Cable are required to read Commodore 64 disks directly. If you have chosen an Amig @-a drive, you may then select whether or not to emulate a 1541. Click on the prompt to the right of the drive selection to toggle between Standard Amiga and 1541 Emulation. If 1541 Emulation is selected, a file called C1541 will be created on the disk in the specified drive when you issue the format command from the 64 (see Disk Commands section). This file holds the same amount of storage as would a standard 1541 disk and will respond in almost exactly the same manner a "#s a 1541 disk drive. If the 1541 Emulation option is not selected, the drive will be less compatible with some 64 software but you will have the full storage capacity of the Amiga disks and be able to access files that are stored in standard AmigaDOS format. When the disk is not emulating a 1541, there are only two file types, PRG and DIR. All program (PRG), sequential (SEQ) and user (USR) will be displayed as program (PRG) files while Amiga sub-directories are displa nyed as DIR. Relative files are not supported when Standard Amiga is selected. To access an Amiga drive subdirectory, you must assign an unused device name to the name of the directory you want to access in your startup-sequence. For example, if you want to access DF0:C64Programs as a sub-directory, you can enter ASSIGN:DF3: DF0:C64Programs in your Startup-Sequence. This allows Df3: to access the sub-directory on your DF0: disk. Note that DF3: may be replaced with any unused device name, including DF0-3, DH0-3 and RAM:. COMMODORE 64 DRIVES Commodore 64 disk drives (with the Serial Interface) may be used by selecting C64 as the drive type. You may also access a Commodore 64 disk drive by device number other than the number it is set to in the disk drive's hardware. All Commodore disk drives default is to device number 8. If you want to use an Amiga drive as device 8 and the Commodore drive as device 9 (even though it is hardwareu- device 8), you could set the device 9 prompt in the configuration settings to C64 and the device type prompt (beside it) to Serial Cable 8. This would tell The 64 Emulator that whenever an access is made to device 9 to translate it to use device 8 on the serial bus. To access any drives when using The 64 Emulator, you must specify the appropriate device number (8 to 11) it is assigned to when issuing disk drive commands. It is therefore possible to have (for example)讘_q a Commodore 64 drive as device 8, Amiga floppy drive 0 as device 9, an Amiga hard drive as device 10 and a RAM disk as device 11. PRINTERS Printers are selected in much the same manner as disk drives. There are two device numbers (4 and 5) assigned to printers during 64 emulation. Through the use of the Configuration Editor, you can assign each of the two devices to one of three printer types: Amiga parallel, Amiga RS232 or Commodore 64. Amiga Parallel Printers p Amiga parallel printers are connected to the parallel port on the back of the Amiga. To select this type of printer, set the printer type to PAR:. Amiga Serial (RS232) Printers Amiga serial printers are connected to the serial port on the back of the Amiga. To select this type of printer, set the printer type to SER:. Commodore 64 Serial Printers Commodore 64 serial printers are connected to the parallel port of the Amiga using the Serial Interface cable (or alte>;`rnately connected to the 64 disk drive which is in turn connected to the parallel port of the Amiga with the Serial Interface cable). MODEMS The 64 Emulator supports any standard Amiga modem connected to the serial port. The 64 Emulator will not work with any Commodore 64 modems designed to plug into the Commodore user port because the user port is not present on the Amiga. PORT CONFLICTS As several of the peripherals mentioned above require the same Amiga portB, a potential conflict arises if two such devices are required to be on-line simultaneously. The two possible conflicts are between ReadySoft's Serial Interface and an Amiga parallel printer and between a modem and an Amiga Serial (RS232) printer. If such a case arises, a prompt will appear asking you to connect the device that the 64 requires. Once the device is connected, click the left mouse button to continue or if you don't want to use the requested device, pressֆ0 the right mouse button to cancel the prompt. The 64 Emulator remembers which device is currently connected and will only request a change if a required peripheral is not connected to the Amiga. MOUSE/JOYSTICK PORTS The Amiga has two control (joystick) ports which can be configured to allow the use of a joystick, the Amiga mouse or a light pen. The ports must be set for the peripheral that is currently in the port (joystick, mouse, or light pen).

The output of U11 is used to trigger the ramp generator formed by Q21 and Q22. Ramp charge time is controlled by C52 and is designed to accomodate the large timebase errors present in VCR playback. Ramp charge time is critical in PLL design: steeper ramp means high gain and less lock range, slower ramp means lower gain but increase in tracking range. The D.C. operating point for this loop is determined by a voltage divider formed by R106, R156, and R157. It is chosenٙ/ to give maximum dynamic range. Error signal on C78 is buffered by dual op-amp U20, section 1. Loop time constants are determined by the R105, C61, C67, R131 around section 2 of U20. The output of this section drives the VCO, closing the control loop. (3) COMBINING SOURCE AND COMPUTER VIDEO Now that the Amiga computer is synchronous with the source video, computer and source video is combined. U8 alone performs the overlay function. The main function of U8 (TDA3301) is to dec;ode composite video into its red, green, and blue components. First, source video is split apart into chrominance and luminance. Network L1, C27 and R52 filters out chroma, passing luminence only information to U8-37. Network R83, L3, C43, and C28 passes only chroma information to U8-1. U8 also internally has a 3.579545 MHZ PLL. By utilizing luminance, chrominance, sandcastle pulse, frame pulse (U28-29) and an internal PLL, video is decoded. U8 also has inputs for external analog RGcL2B video. Computer RGB is applied to U8 pins 25, 26, and 24 respectively. The signal that determines if source on computer video is ultimately output is pixel switch (J9-4). This is a software generated control line from the Amiga. One section of gate U5 is used to force pixel switch to show only computer video when source video is lost. Each video output of U8 is D.C. clamped for black level stability. The following is a description of just the blue channel. Blue video exits U8 on gpin 14. The level is divided down by resistors R71 and R72 and feedback to pin 16 completing the loop. C25 is used to hold the sampled clamp value (see Motorola data sheet for full details). The blue video is then amplified X2 by transistor feedback pair Q10 and Q11. Gain is set by the ratio of R60/R61. R63 gives the characteristic line impedance of 75 ohms (J10-5). Operation is similar for the green and red channels. Other components around U8 are best understood by consulting the T)aIDA3301 data sheet. A hue control (R134) is provided to allow user color matching of computer and source video. (4) MIXING SOURCE AND COMPUTER AUDIO The left audio channel mixer is described. Source audio (J3) is capacitivly coupled by C82 and terminated in an impedance of 47K. Electronic switch U22 (CD4066BE) is used to disable source audio via computer control. It operates as follows. The control to enable/disable source audio is encoded in the vertical and horizontal blanking  MxyUinterval of the pixel switch line, software setable on the Amiga computer. U18 samples pixel switch during the vertical interval, using the frame pulse to latch audio status. The latched output (U18 pins 6&5) is used to control transmission gates in U22. Data is latched on or about line number 10. No horizontal sampling is done. Computer audio enter on J5. Passive mixing network R140, 141, 143, 142 and control R132 combines the two sources. Pot R132 allows user control relative lev 'els. Right and left mixing is controlled by the same shaft. Feedback pair Q19 and Q20 provide gain (x3) to make up for losses in the passive mixer. C83 provides bandlimiting (20KHZ) to reduce noise pick-up within the box. Audio and video grounds are kept seperate until the connector (J9). (5) ENCODING THE RGB VIDEO Analog RGB signals are encoded into NTSC or PAL by a single device (U21) from Motorola, number MC1377. This IC requires only continuous subcarrier and composite sync t `Ro output composite video. Subcarrier is obtained from the oscillator in U8, coupled by C45. Sync comes from the output of selector U5. The analog RGB signals (0-1v amp.) from U8 are coupled into pins 3,5 and 4 of U21. Inside the MC1377 a resistive matrix and multipliers transform RGB into an encoded chroma signal, output on pin 13. To reduce interference with high frequency luminance information, the chroma is bandpass filtered to 1 MHZ by T1, R11, C72, and C70. Chroma re-enters the  chip on pin 10. The luminance signal is derived via an internal matrix from the RGB input?? output inverted on pin 6. TD1 delays the luminance information by 400 ns making up the time delay caused in the chroma path by the bandpass filter. Chroma and luma are summed and clamped inside U21, emerging on pin 9 as composite video. Emitter follower Q15 buffers the video to J6. Color burst is also added to the video inside U21. External components R95 and C69 determine burst position. 0iPin 16 is a stable zener derived 8.5 volts.

(*READYSOFT) Overscan not yet supported.GA (AMICUS) Jez is paler than me. Imagine that! (DR*GLENN) hey jez...glad to see your back...we thought you d3_isappeared in s fran (AMIGA*BOB) Time for me to scoot....nite all and thanks again Ready- Soft!! (*READYSOFT) yes we use custom chips! (UK JEZ) demo*d... not all.. ive been watching one per day.. sure are good.. im heavily in your debt... soon to be paid back i hope! ....and on and on for another hour or so. ## 30 ## 00? (CBM*HARV) spoling...about $150 come february or so (DR*GLENN) hehehe...i had my 2000...bought camcorder this year! (UK JEZ) .. you d 7s set by the ratio of the input series resistor (R26, R31, R27) to feedback resistor R28. The sandcastle pulse at Q6 collector encodes blanking information from 0-5V dc and burst timing from 5-10V dc, with the pulse looking very much like it's name implies. H/2 reset is generated by U14 and U17. The input to one-shot U14 is regenerated horizontal from the 28 MHZ phase-locked loop. U14 time constant is 33 microseconds, making a square wave at horizontal rate on pin 12. Dual D-type f elip flop U17 is wired as a gated divide by 2. The H/2 reset output (J9-21) is a negative going pulse 32 microseconds wide, with the edges retimed to the Amiga computer color clock (J9-6). This re-timing to color clock is required to guard against metaphysical states in the Amiga graphical devices. (2) 28 MHZ PHASE LOCKED LOOP The circuitry to generate the 28.636363 MHZ clock is comprised of the voltage controlled/crystal oscillators, phase detector, and divider, the classic phase-  wrlocked loop. The VCO has some unique features. The genlock peripheral must generate a stable master clock, allowed to vary only a few percent in genlock mode. When there is no video on the peripheral input, crystal stability is required for real-time clocks and counters. To complicate things the Amiga computer cannot tolerate large timing variations when switching in and out of genlock mode, missing a clock cycle is catastrophic. Therefore, a circuit was designed so that a crystal omscillator can "tickle" the voltage controlled oscillator for completely synchronous mode switching. Q24 and its associated circuitry is the 28 MHZ Colpitts crystal oscillator. Q23 is a buffer to prevent loading of Q24. Power for Q23 and Q24 is controlled by Q4, supplying current only when there is no input video (xtal mode required). Q13 and its associated components form a Colpitts voltage controlled oscillator. The frequency is changed by varying the D.C. control voltage on CR7, ;!a varactor diode. C60 varies the VCO center frequency. The connection made by C63 and R128 allows the crystal oscillator to "tickle" the VCO. For an in-depth discussion on oscillators, consult "Crystal oscillator Circuits" by Robert J. Matthys. Q12 buffers the 28 MHZ clock to the Amiga, (J9-1) setting the correct TTL levels with R64 and R65. L2 and C41 filter the 28 MHZ to reduce RFI. A synchronous divide by 1820 is formed by U6, U10, U13, U16, U4. U16 is a schottky device becauo+z se of the frequency involved. Operation of this circuit is straightforward. The output of U6 pin 13 is a stream of pulses at a horizontal rate. This is called regenerated horizontal and is never interrupted, an Amiga requirement. This signal is one input to the phase detector. The phase detector used is the analog sample and hold type. Basically, this detector works by sampling a ramp generated from one comparison frequency (feedback) with a sample pulse derived from the other (re f ference). The output D.C. is used to control the VCO. The reference input for this phase detector is the horizontal component of input video, applied to one-shot U11 pin 1. Delay in U11 is about 1/2 line, with a potentiometer to fine tune horizontal position, R133. U14 generates a short sample pulse (275 nanoseconds), level shifted by Q14. Q14 collector drives sample gate Q25, with the sample voltage held on C78. The feedback input goes to the other section of U11, again adding a 1%Rrv3 megs usuable (CMI*BILL) Remember that you have to configure the second drive as device 1 rather than 0.

(ANDROID) INFO#24 p 80: Mac Emulator costs $15!+^0 and is only a 128k system unless you get new chipset[then 1meg Mac +] (ANDROID) Readysoft? (*REK) <-thinks we should go back into auditorium mode (*READYSOFT) send us an APPLE II emulator for the Mac. (LUGNUTS) Even faster with LUCAS installed :^> (*BUD*H) You can buy Finder or , I think it's freely distributed at Apple Dealers. (MIKE-SPAR) now I'll have to subscribe to Mac Journals too! (TOM H) <- agree... (*READYSOFT) ANDROID... LISTEN. (*BUD*H) Readysoft, there is one available ",%A>already, emulates a IIE (*READYSOFT) YOU can use ALL your memory with the old chip set (AMICUS) Anybody have experience putting in a second internal drive in a 2000? (J. WOLF) Amicus, I'm trying to find out where to BUY the MAC OS. (ANDROID) listening (AMIGA*BOB) Yep John (CBM*HARV) hey john, this is a MAC conference! :-> (CMI*BILL) Yes, I have, AMICUS. (*READYSOFT) system and finder can be purchased from Apple (ANDROID) ok. So INFO was wrong. they do that some times. sorry. (DR*GLEN#-N) yes john... look at the dip switches in the back (J. WOLF) Amicus, I installed my second interal 2000 drive by jut following the directions. (NY*JIM) Gee, we can finally run VC>! ;-> (NY*JIM) er, VC0 (CBM*HARV) VCO? yeah. (AMICUS) Bob, I have a chinon, same as the default one, do I need to pull that J200 jumper? (J. WOLF) What is VC0? (*BUD*H) How about HyperCard? (AMICUS) Well, I didn't get directions. I junked a spare drive I had laying around... (OJS566) Readysoft, do you mea$!uXn if we have 3 meg we can use all of it? (*READYSOFT) Hyper card runs (NY*JIM) Visual Conferencing, what ACO was based on (CMI*BILL) Yes you do, John. That jumper enables/disables DF1:. (DR*GLENN) amicus..there was something you had to fix in the back- ...jumper or dip swirch (ANDROID) oh yeah, Red Ryder. Heard some good stuff about that one (J. WOLF) Ready, what about using MAC add on hardware? (AMICUS) And scavenged standoffs and screws from the junk box... (*READYSOFT) yes all of /aront of me say the mac bit density stretches from 1.3 microsecs, to 2.0... sounds like its feasible to read more than 34% on an Amiga! indeed i do! (J. WOLF) How much is A-MAX? Do you guys supply or know where we can get 128K roms? How is the screen proportions?...How does A-MAX run with a Processor Accelerator at 14mhz? ga (*READYSOFT) Approx $150....We wont supply roms, but Computer Shopper has listings. Under inv0oi nestigation are other sources .....Screen proportions are good in interlaced or 640 by 400 mode. We have several screen formats incl. a 512 by 342, for full video compat....we also support the A2024 in 1008 by 800 line mode and the new chip set which gives 640 by 400 non interlaced. (RON K) Can AMAX support a SCSI hard drive instead of floppy? Will my external drive...attach to it and be readily1 accessible? ...also will it work with all amy models or is it a 2000 card (*READYSOFT) Hard disk support will not be in first realease. All amiga drives can be used.....AMAx works with ALL Amiga mod els.....the amiga drives use a special AMAX format under the Mac the format used is runs much faster under the Mac OS then Amigdos would . (TERRY R) for those of us who are going to call 2ɧAnour dealers on monday to place early orders what will your upgrade policy be when newer..and better releases come out. Is there a trade in policy> we need at least 4 units NOW !!! (*READYSOFT) Registration cards are supplied. You will be notified of upgrades for reduced cost. (SRU249) WILL IT DO COLOR WILL IT WORK ON A-500 ? GA (*READYSOFT) Works on ALL amigas.....Macs other than Mac II's are mono, so we can only 3use 2 colours at any time. GA (PROF. HAWK) It will allow for full multitasking with the AMIGA right? Also physically, how big is it? (*READYSOFT) Sorry, multitaksing won't be in the first release < we have future thoughts for this tho> the cart is 2 inches by 4 inches with a cable to connect to the drive port to the cart. (CRYO) PA ? not answered (CBM*HARV) DOES AMAX WORK WITH THE CMI PROCESS ACCELLERATOR (*READYSOFT) p4;robably. send us one and we'll find out. GA (*HARRY) Without any hard disk support, what would you consider a acceptable Mac setup to run lets say PageMaker . On the Amiga that is. (*READYSOFT) We run Pagemaker 1.2 on just about any system....eg. 1 meg a500/a2000 or 512k a1000. GA (SLEEZYCZ) This question may have already been asked but I got here late. Does AMAX use amiga drives? And do you recommend 5L particular MAC roms over others? and what do you think the price will be? GA (*READYSOFT) yes, with a custom format....we can use 64K or 128K roms...128's are better....price:$150 tentativley for AMax (*REK) do you lose use of your current external disk with the card in place ... (*READYSOFT) no we have pass thru for ext drives; all of which may be used with Amax. GA (*REK) if so how dow A1000 use those ? ga (6"*READYSOFT) No you need an Apple compat 800K dble sided drive. full disk compat. with a mac 800k drive. ...limited compat with mac disks in amiga drives. (*BUD*H) I used Amax at world of commodore, thought it was great. Will it notice my 2 meg expansion? When will it be released? When will it be available (*READYSOFT) Yes we have mem expansion support now. release about Feb. ---------[END OF FORMAL PORTION OF CONFERENCE]-------7{,----- (The remaining 60% of this transcript is a basically unedited capture of the informal conversation which followed the hour-long formal period above... all of the "hellos" and "goodbyes" have been mercifully removed :-). (CBM*HARV) OKAY I HAVE A QUESTION.. FOR THE BENEFIT OF READYSOFT, HOW MANY OF YOU ARE DEFINITELY/PERHAPS/MAYBE/NOT INTERESTED IN BUYING AMAX WHEN IT IS RELEASED (AMIGA*BOB) Yes (DJJAMES) i have my roms already (ANDROID) I have heard 8֭ the using the old chipset will only give you a 128k mac but the new chipset will do a 1meg Mac +.What new Chipset?me (CRYO) ReadySoft: Does Amax use the Amiga Cust. chips for drawing or your own routines? (ALLEN M) I will (DR*GLENN) maybe (SLEEZYCZ) Very much so! (NY*JIM) <---- quite interested (OES928) I will as soon as it available (TERRY R) Readysoft: would it be possible for you to upload complete specs for AMAX to the library here. It wou#7ld help a lot. thanks. (-NOMAD-) sounds ok (CMI*BILL) probably. (RON K) Will you accept direct orders? If so address and order info puhleeze! GA (GROGERS) FlashBack question: how long does a backup < 20 Meg > take and whats the error correction? (JIM*M) I will (CRYO) < will get one for development. (DULNERD) maybe (TOM H) Yes, with more info (ANDROID) me (LUGNUTS) Mega Interested !

(*READYSOFT) We have run Megaroids, Loderunner. Mac games pale compared to Amiga anyway.... often copy protected which causes problems with Amax. The Amiga mouse emulates the Mac's; no problems. (UK JEZ) readysoft... is A-max code in any way related to Dave Small's stuff?... also, Can Amax read mac format disks with no extra .4 disk drives...? if not, why not? (*READYSOFT) No completely independent of Data Pacific/DSmall....We can read only 34% of a Mac disk in an Amiga drive.....because of the multispeed format that the Mac uses our cart. has a connector for a 800K mac drive which gives full disk compat ..... YOU OWE US A STAR GLIDER II . (UK JEZ) thanx readysoft... my specs in f to your Amiga, connect the wide end of the cable to the parallel port on the back of the Amiga and the round end to the back of the disk drive. The difference between the Amiga 1000 interface cable and the Amiga 500/Amiga 2000 interface cable is the connector on the wide end of the interface. Once you have connected the Serial Interface you will have to set the system configuration to allow The 64 Emulator to access the serial devices.

SERIAL INTERFACE CABLE The 64 Emulator is sold in three different configurations - without a serial interface, with a serial interface for the Amiga 1000 or with a serial interface for the Amiga 500 and the Amiga 2000. The Serial Interface is a cable that allows a Commodore 1541, 1571, 1581 or compatible disk drive to be connected to the parallel port on the back of the D Amiga. With this interface, The 64 Emulator can access Commodore 64 peripherals that would not be otherwise compatible with the Amiga. The primary advantage of using a disk drive such as the 1541 is increased compatibility with 64 software and the ability to load copy-protected software. Be careful when connecting cables and peripherals to your Amiga. If cables are not plugged straight into the port, they can sometimes reset your Amiga.

Hypercard under Amax an9io ResetpexGenlock circuit operation description ----------------------------------------------------------- Enhancements: One feature that space does not allow for now is the ability to have software control of pixel switch disable. Now this is done with a mechanical switch. Pixel switch disable allows the user to completely ignore background video, yet have the Amiga computer genlocked. This eliminates the problem of software having to be written with genlock in mind. It would add $5-$10D to cost of goods. The control bits would be encoded in the vertical interval, as audio on/off is presently done. Eight to sixteen functions (bits) could be controlled once this ability is on the board. CHROMA KEY -- since all signals are in RGB format, it would be easy to selectively insert video based on color level. Additional circuitry would add about $10, but would not fit in the existing case. ============================================================ Circuit descriptiont\ The purpose of the genlock peripheral is to synchronize the video output of the Amiga computer with another video source such as camera, broadcast, or VCR. Circuitry inside the peripheral allows for the overlay of computer graphics on whatever video source is connected. Also provided are facilities for stereo mixing of computer and source audio. Input to the genlock peripheral is composite source and analog RGB computer video. Output video is in the forms of composite and analog RGB for high-resolution viewing on an RGB monitor. Also output are a master 28.636363 MHZ computer clock, H/2, and V/2 video resets required to synchronize the computer's graphic devices. Power for this device is derived from computer +5, +12, -5 volts D.C. rails. Circuitry in the peripheral is divided into several main functions which are: 1) regenerating the horizontal and vertical components of the original composite source video, (2) phase locking the 28 MHZ clock to input video h.uorizontal timing, (3) combining source and computer video, (4) mixing source and computer audio, (5) and encoding the RGB overlayed video into NTSC or PAL. (1) REGENERATING HORIZONTAL AND VERTICAL TIMING Source composite video enter on J1. Transistors Q16 and Q7 form a feedback amplifier with a gain of 3. Simple sync tip clamping is provided by CR3, whose clamp voltage is set by CR4. The net effect is to clamp sync tips at around 0 volts. Comparator U3 strips the sync off of the 3Gclamped composite video on it's pin 4. Comparator trip point is set by resistive divider R55 and R49 to be at about the 50% amplitude point on the sync. On the output of U3 (pin 9) is composite sync at TTL levels. One-shot U1 is a digital integrator designed to detect when video drops out for more than 12 lines. The output of this detector forces crystal mode operation (Q4 enables power to the crystal oscillator) and selects computer composite sync (J8-19) to insure a stable monitor picture. Nand gates in U5 form the sync selector logic. The composite sync output of selector U5 is decoded into its horizontal and vertical components. The time constants of differentiator C21/R56 and one-shot U12 are chosen to trigger only on the horizontal components of sync. Output on U12 pin 5 is a series of pulses at a horizontal rate. One-shot U19 forms a negative going pulse 4.7 microseconds wide buffered by U23 for monitors requiring seperate horizontal sync (J10-11). The  time constants of integrator R77/R76 /C34 and one-shot U12 are chosen to trigger only on the vertical component of composite sync. The output on U12 pin 4 is a pulse 90 microseconds wide on line 3 every vertical interval. One-shot U19 generates a negative pulse 200 microseconds wide buffered U23 for monitors requiring seperate vertical sync (J10-10). The graphic devices in the Amiga computer require reset every other vertical interval in genlock mode. Dual-D flip flop U15 performs t 9Yhis task. It is basically wired as a divide by 2 with horizontal sync clocking the first stage. This causes the V/2 reset pulse to be synchronous with horizontal, one line wide, retiming its edges. V/2 reset is buffered by R10 because at times the Amiga computer will output vertical pulses on J9-23, (ie. genlock mode not selected with peripheral attached). The sandcastle generator is made up of U2, U7, Q5, and Q6. This circuitry generates a multi-level pulse, encoding burst and blan ?݇>king timing information for U8, the chroma decoder. One-shot U2 time constants are chosen to generate the blanking portion of the sandcastle pulse. One-shot U7 time constants are chosen to generate burst timing. Transistor pair Q5 and Q6 form a low impedance wide-band inverting summing amplifier. R27 supplies a D.C. offset to give the correct D.C. levels at Q6 collector for U8. R26 and R31 sum in the blanking and burst signals respectively. The gain of any signal to this amplifier i4 printer.resetpF A Reset Switch for your Amiga. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Now some people might say Why would you want a reset switch in a amiga? Well think of all those times that you wished there was only one key to press instead of three- like when you have one hand busy holding something - like a beer , food , phone , whatever. I personally don't know how I managed before I put this in. This is a very easy mod. Solder one wire to pin 18 orʳf the 68000 and to your momentary switch Solder other wire to ground (the metal shroud is fine) Bingo-thats it.

The modification includes special wiring such that the drive mag y again be used as DF1: with the Amiga's power supply. Accompanying this article are schematics and illustrations as IFF ILBM Hi-Res format, created 640x400 with one bit plane, in the file ModSch.iff-H which is available on a FAUG Hot Mix disk and on a "Fish Disk" under the name ModSch.iff-H. Included also is the hi-res digitized photo P6-J6.iff-H which illustrates the plug and jack used for the external power supply connection. The IFF images may be displayed on the screen with thQe "ShowALL" program, and may also be printed with Deluxe Paint (tm). This project is not for the faint-of-heart since it requires drilling a large hole in the A1010's case. The internals of the A1010 drive are fragile; working on a disk drive is not like working on your car. Also, opening the disk drive case will void your warranty. It may be worth your peace of mind to contract an experienced technician for the modifications. Common sense and a good mechanical aptitude are essenm,tial. Take your time and do not rush. The modifications have functioned correctly WITH MY DRIVES since March 8, 1986, when I performed the operation. You are responsible for verifying the arrangement of the connectors and power distribution inside YOUR drive since there may have been production changes and model variations. The modification and details described in this technical note are provided "as is", without warranty of any kind, either expressed or implied, including, but ynot limited to, the implied warranties of fitness for a particular purpose. The entire risk as to the results and performance of the modification is assumed by you. In no event will I be liable for direct, indirect, incidental or consequential damages resulting from the use or (mis-)application of this information. Prior to starting the modification, you will need to acquire a power supply capable of supplying 2W at +5 VDC (0.400 Amp) and 2W at +12 VDC (0.200 Amp) for each disk drZYive. "Surplus" power supplies from modems are readily available for approximately $10 each and are ideal for this application; be sure you get a regulated power supply and not just a simple transformer. You should also purchase a mating plug and jack for connecting the power to the A1010's circuitry; hardwiring an external power supply directly to the A1010 is not advised. The jack should be one that does not extend too far into the A1010 case since there isn't much room; examinatsT/" SCSI adapter Monitor program 2/28/87 Rich Frantz +++++++++++++++++++++++++ EQUATES +++++++++++++++++++++++++  ++++++++++++++++++++++++ Display ports ++++++++++++++++++++++++     () ( )!

I used some surplus connectors manufactured by Amphenol; there is no part number on the connector but the illustration accurately depicts the part I used, which also has a locking twist-tab to prevent accidental disconnection. The remainder of this article references the illustrations, so either make a hard copy of ModSch.iff-H, or display it on your monitor using the ShowALL program. The drawings may flick r`er if your monitor does not have a long persistance phosphor, so adjust the brightness and contrast as suitable. Opening the A1010 case requires unscrewing the four screws on the underside at each corner. Inside will be a metal RFI shield covering the back of the disk drive and the interface printed circuit board. Remove all screws that fasten all parts to the plastic case, making note of each screw's location. I find that making a rough sketch of all the parts on a piece of note + paper and pushing the screws into the paper at the proper location provides an easy and safe way to assure that all parts are restored to the proper location upon reassembly. Examine all parts while they are still in the case. Try to find a location, preferably on the back panel, where your jack can be placed without its pins shorting against something and, most importantly, where it will fit with adequate working clearance.

As a hardware type I have often been envious of the ease with which software can be shared among developers and users alike. Ideas and techniques can be distributed through BBS networks to the general benefit of all. In contrast, hardware developers lead a comparitively solitary existance, the exchange of ideas i.~mpeded by economic and logistical problems. Can there be such a thing as Public Domain Hardware? Obviously no one can give away printed circuit boards, but perhaps we can do the next best thing: give away as much information as possible and make bare PCB's available for as close to cost as shipping allows. The project is a platform board called LUCAS (Little Ugly Cheap Accelerator System). which replaces the 68000 in your Amiga 1000.

I know that it is fragmented, but I am trying to get something together quickly. Feel free to send me your comments. At the present time this design does not support DMA or AUTOCONFIG'ing. The "net-list" also includes parts for an optional 2 meg. memory add-on. At this time the memory does not work! I have to check my equations and analize that section of the tRzboard. The memory section does NOT upset the AMIGA or the SCSI interface. There are no special considerations when building the board. It runs off of the AMIGA's power supply and plugs into the EXPANSION PORT . The board uses 1 special part: NCR53C80 (sorry about that.) I used it because it handles most of the SCSI interface, and eliminates alot of "LS" chips. (The NCR53C80 is the CMOS version of the SCSI controller used by APPLE and most other venders!)

When you first build the board, the clock may gain or loose a few seconds a day. You can correct this by adjusting the variable capacitor in the clock circuit. The best way to do this requires patience. Note the amount of error in a known amount of time, say a day or a week. Make an adjustment of perhaps a quarter turn on the capacitor (remember the direction). Wait this amount of time8CC The USENET (comp.sources.amiga) distribution of the LUCAS project is different than what you'd find on BIX, or get from the author. The Mandelbrot programs & sources, benchmark programs and the utilities (SetCPU and DeciGel) were omitted, since they are available elsewhere and because many people will be grabbing these files only to determine if they want to build the board. The Commodore utilities (More and IconX) have likewise been removed, as well as the copyright notice they r8+Adequired. In addition, all the ".info" and ".fastdir" files have been removed from this distribution, and most of the files have been renamed. All the documentation has been reformatted to fit in 80 columns.

Note the change in the error. Now you can correct the capacitor by the proportional amount. If the error is worse, the capacitor must be turned in the opposite direction from the first attempt. If the error is of the opposite sense, then the first adjustment overshot. If a quarter turn is worth a second a day, then to correct a second a week will require a one twentyeighth turn. Since such delicate adjustments are hard to make, you may need several tries. You can quit w53hen the clock is sufficiently accurate for your needs. Ultimately, the clock can be adjusted for about one second a month error.

If you find programs which don't work please let me know and I will post them for those who are still considering getting a LUCAS board. By the way FA-18 is gorgeous with the LUCAS board installed. I welcome any information or bugs which you can provide. A500 and A2000 OPERATION: For the 500 there is good news and bad news. The good news is the LUCAS board works in the A500. The bad news is that you will never get the case back on. No one so far has tried it in a 2000 but X bI'd bet the same is true. I have no plans to do a board for the 500 or the 2000. I will gladly give anyone the PCAD files so they can layout the board to a different form factor. I built the board for the 1000 because I have a 1000 and I still like it best (No 1 meg chip ram eh!) and because I'd like to save the 1000 from becoming a door stop. PROBLEMS? I've spent considerable time debugging the board to make it work. Here are some of the problems I have run into and perhaps theXЧSy might help. Please remember that the whole purpose of making this board PD was so that the Amiga community at large can help those with problems, but more importantly, with a full disclosure of the design we can benefit from all those hackers out there who will make improvements to the board. Already we have boards that work at 20 Meg. and 25 isn't far off. I will post on USENET and BIX all the traffic good and bad that I feel should be generally known. I will also post the bugs, XI2#Dsoftware that doesn't work, peripherals which don't work, etc. If you insert the Kickstart disk and it runs for a couple of seconds then pops the kickstart screen back at you, and you are sure that this is a valid kickstart disk, try changing U9 from an ALS part to a LS part, or a 7474 part. this should solve this timing problem. This is a generic fix for all problems, changing the type of 74 for U9 will make some peripherals which don't work, work like a charm. It is a quick test sX o try it if you getting strange behaviour. If Kickstart is taken in OK but it gets to the point that it is about to pop the workbench screen then goes bonkers try changing U9 again. If this doesn't help you might have a gounding problem. Gounding problems. We have found that the Amiga 1000 has a very noisy ground plane. Some Amiga's will only take one peripheral, two and they cough. Dominic at COMSPEC came up with a grounding mod that I now do as a matter of course to all Amiga'sXNņ I open up. The problem he solved is that there is a slight voltage differential between the Amiga daughter board and the expansion connector ground planes. To remedy this connect a piece of wire between the four pals ground pins on the daughter board and the ground which surrounds the expansion connector. These pals are J6, K6, L6, and N6 at the far end of the daughter board. The ground pin is pin 10 which is the pin at the upper left of the pal as you look at it with the Amiga faciX ,*_ng you. Bus these four ground pins together then run a wire to the gound which surrounds expansion connector (Use an ohmmeter to be sure). Scrape away a small section of the solder mask which covers the ground and solder the pal ground wire there. This can make your Amiga much more robust with 3 and 4 peripherals attached. There is also a place on the LUCAS board to attach a secondary ground wire. If you look at the board there is a dedication which says "Special Thanks to Dr. Brain X!jGaines and ANAKIN". Look right on top of the N in ANAKIN and you will see a small GND marked. Solder a wire through this hole on the bottom of the baord (scrap solder mask first) and attach it to the same place as the pal ground wire. It is always a good idea to if your having problems to check the seating of all the chips, especially the seating of the 64 pin socket which mates the LUCAS Board to the AMIGA 68000 socket. It is also a good idea to check that none of the disrete chipsX" or pals have a pin bent underneath them instead of into the socket. If you still are having problems E-Mail me on BIX or USENET (see the article) and I'll try to help. solder mask which covers the ground and solder the pal ground wire there.

MAKE SURE THE ORIENTATION OF THE 68881 IS THE SAME AS ON THE LUCAS BORAD SILK SCREEN)) NOTE IT DOES NOT HAVE THE SAME ORIENTATION AS THE 020. Also make sure that all the pins are correctly seated. If you still have problems see below or the article as to how to get hold of me. Now back to the 99% of you who have had no problem so far. The nX}]ext indication that everything is OK is you will hear the Amiga's little boot song. Don't let the fact that the song is slower disturb you. The cashe hasn't been enabled yet and alot of useless fetches are going on. Next you should see the Kickstart screen. We are now about 70% sure everything is going OK. Insert the KickStart disk and away we go again. The hardest test that the Lucas board has to pass is putting up the Workbench screen. Just prior to doing this, interrupts are enabX led, the 020 cashe is enabled, the 68881 is talked to to see if its there, and the autoconfig stuff happens. If you get to the workbench screen your probably not going to have any futher problems. So insert the Workbench of your choice. Try running the bench marks to see if you are operating at the same level. Run the Mandfast program in the Mandelbrot directory this will verify that the 68881 is working properly. Next connect your peripherals and insure that they work as well. SomeX|Ȃthing your going to have to do is tune your particular AMIGA to the LUCAS board. This is done with U9. That is why I asked you to buy several different types of 7474. If your operation isn't what it should be try different types of 7474 in the U9 socket. The first to try is a 74LS74. My buddy Eric Haberfellner is convinced that a Texas Instruments 74LS74 works with all configurations he has run into. I contend that the LUCAS board insists on having one piece of unexplained magic. I'vX|e tried to fix it but it seems what works for one AMIGA doesn't work for another. The important thing is that so far no one who has bought a LUCAS Board has been unable to get it going. Just play around and have faith. I really do know how the rest of board works and once you get the right chip it is solid as a rock. Historical Note: I got in to this U9 mess when I did the board layout. PCAD allows you to switch identical gates or sections of a chip in order to improve the layout. XS When I gave the command that it was OK to switch gates I forgot that I had 2 74F74 and one 74LS74 on the board and PCAD wasn't going to complain so it switched an F part for an LS part and now we all have to go through this nonsense. I think it sounds better though to say you have to tune your AMIGA to the LUCAS board. It does show how critical the timing for DSACK is, read the article if you want to bored to death about DSACK. Seriously it isn't a big problem. EVEN FASTER.. SXZ o far, 20 meg. seems to be the limit. I've had it working at 25 meg. but it was a little flakey. I'm trying -D2 PALS and the inevitable U9 tricks. I'll post it if I'm successful. We have found that 12 meg. parts work just fine at 20 meg. The reason for this, I think, is that when used in an AMIGA, none of the more exotic 020 modes are used. I designed the board for operation at 16 meg. and you should use 16 meg parts, but if you want a cheapest possible way to get a LUCAS board goiXaPng try 12 meg. parts, with a 12 meg. xtal. If it works you can try xtals all the way up to 20 meg. I can't tell you definately it will work but no one so far with 12 meg. parts has found any problem operating at 20. "Ya play de game, Ya takes yer chances" EXPANSION: I am currently designing a 32-bit wide memory board using 100ns 1 meg DRAM's. Unless your doing alot of floating point stuff, the Lucas board won't give you miracles. If your LUCAS board is running at 20 Meg. (this isXA( the configuration I know best) than you can expect a 35% - 40% speed increase across the board. The whole point of putting the 020 in your Amiga is to one, give you a 32 bit wide upgrade path, and two, the 256 byte instruction cashe sure helps. If you connect 32 bit wide memory to the LUCAS board you will get about 200% speed increase. Ofcourse floating point stuff, if it uses the 68881 will indeed appear miraculous. If anyone also wants to have a go at a memory board the expansionX connector is documented in the drawings and in the PCAD documents. If you have access to fast SRAM an SRAM board with no wait states would sure fly. Once I get a good memory board layout I'll make the bare board available as cheaply as I can, but don't let that stop anyone from doing one also. COMPATABILITY: The LUCAS Board is works with most of the Peripherals I've tried. Comspec Memory Board, Comspec Hard Disk, Microbotics Memory Board, EASYL, and Supra Hard Drive. The only pX}Òeripheral that has failed is the Allegra 512K memory board. I can't guaratee anything beyond this at this time. I will however post compatible and incompatible hardware and software as reports come in. So far LUCAS is very compatible with the software we've tried. The only software that seems to fail are those games which use heavy copy protection, like Carrier Command. Jet will work if you turn the cache off with SetCPU. DeciGel will allow those programs which do move SR's to behavXtd. You could use tants for the .47 parts if you cannot find them in monolithic. It is important to use the 330 ohm and 220 ohm resistors as specified. They are standard for TTL clock termination. The 30 ohm resistors are used to help control the over and under shoot on the control lines *UDS, *LDS, R/*W, and *AS. The 16 Meg clock oscillator should be inserted into a gold socket. When you buy your parts you may want to pick up a 20 meg. xtal. Half the people so far are getting awayX with it even though they are using 16 Meg. 020's and 881's. The part you will need for U9 varies from one Amiga to another. Buy one each of 7474, 74LS74, 74S74, and 74ALS74 (they're cheap). I will explain later how to determine which one of these you should use and why. Soldering If you haven't soldered up a board before, find someone who has. It is a simple job bit requires some degree of manual dexterity and a good fine tip iron. Everyone has their own method. I start with the Xsockets, then do the caps and resistors and then the two connectors. If everything is on hand you can do an excellent job in about an hour. This is an important stage, don't rush it. Dual Pin Header Unless your in the BIZ the connector which connects the Lucas board to the 68000 socket can be a bitch to find. However it is pretty easy to make one up yourself from readily available parts. The easiest method is to buy two 64 pin 68000-like sockets (again gold is best) and connect theX 1m together with 64 bits of wire. The cutoffs from capacitors and resistors are ideal. The distance between the two sockets should be about 0.6 inches. Basically you want to raise the Lucas board to the same height as the daughter board. I suggest you cut four bits of wire, attach them to the four corners of the socket and see if the board is of the correct height. Once this is done you can cut 60 more bits of wire and install them between the sockets. Test the height again, if its OKXRJ I suggest you solder in the four corner posts (wires) then solder the assembly to the bottom (solder side) of the LUCAS board. DO NOT use .025 sqaure posts this will permanently destroy your 68000 socket. When you put in the tant capacitors make sure you observe the correct polarity. Positive always goes to the square pad. Note C19 has no square hole, the positive side of the cap goes to the terminal closest half inch hole in the board. If you still confused get out an ohm meter anX  make sure the plus side of the Tants is connected to the 5 volt rail (pin 20 of U4). INSTALLATION: Installation is quite straight forward, rip out the 68000 and replace it with the Lucas Board. Q.E.D. To elaborate, remove the plastic cover and the EMI shield. 5 screws for the plastic cover, 14 for the EMI shield. Gently and with reverence, pry the 68000 out of its socket. I use a small bent screwdriver. Now push the 64 pin header on the bottom of the Lucas board into the 68000 X socket. Do this carefully to insure that each pin goes in properly and that you didn't bend any. Things to be careful about. The ribbon cable from the disk drive can be a pain. Make sure it is lying as flat as possible, and that the bend in the cable takes up as little space as possible. Make sure the board is the same height as the daughter board. If it is too low the Lucas board will not clear the cable and header for the disk drive. This is also important if you want to add somX pme 32-bit wide memory to the LUCAS memory port (96 Pin DIN connector) as this board must be high enough to clear the metal oscillator can in the middle back of the Amiga motherboard. Once you have installed the Lucas board we are ready for check out. When it gets working you can replace the plastic cover. The EMI shield will have to have a small section cut out of the back, if you wish to replace it too. So far no one has done this. Be careful, don't force anything, and don't PANIC X ٦! CHECK IT OUT! In all the years I've been hacking around with hardware stuff, I have only discovered two golden rules for hardware design. Inside every device is some magic smoke which makes the device function. As long as you don't let this magic smoke out everything will work fine, however in all the cases where I have inadvertanly let this magic smoke escape, the device ceased to function. Please remember the following two rules: 1) Don't let the magic smoke out. 2) Don't leX p't rule one scare you. Okay, were going to turn the Amiga on now, if it doesn't work first time don't panic. No one so far has blown an 020 or a 881, and no one so far has done any damage to their Amiga. The only damage that has been done so far is someone used .025 square posts to mate the LUCAS board to the AMIGA. This damaged the socket. Once he replaced the socket and replaced those tree trucks with the proper pins his board worked just fine. If you are really paranoid, use an oX 5*hm meter to make sure that there is no short between the 5 volt rail and ground. You should get about 270 ohms. At this time we are going to put a 74ALS74 in the socket for U9. So, turn on the Amiga, and watch the power light on the front of the machine. It should flash five or so times and then stay on. This is the basic test, if it doesn't do this it will never do anything.
