System: Tandy Color Computer 3
Language: BASIC
Len source code: 94 bytes
Len exe file: N/A
Len code only: 94 bytes
Instructions:
Launch the Windows-based VCC Emualtor (Available Here: https://github.com/VCCE/VCC/releases -> "VCC.2.1.0.7.Coco.3.Emulator.zip") by running "Vcc.exe". From the menu bar, choose "Edit" -> "Paste Text" and paste the two lines of BASIC code. (You will probably have to hit enter after it pastes LINE 2). Then, type RUN (and hit enter)
Description:
Draws the rows using X/Y coordinates ranging from -8 to 8, with 0 being the center line, which allows a "*" or " " decision to be made based on the absolute value of the line position, which resulted in a smaller size than I could achieve by drawing right-angle triangles or text compression.
Comments:
Execution and byte size was also verified in the MAME emulator and on my vintage Color Computer 3.
* This utilizes the Color Computer 3's "high res" 40-column screen and will not run on a CoCo 1 or 2. I chose this because the "low res" screen only has 16 vertical lines.
