8-Bit Show And Tell | Printing Binary in BASIC and Assembly on Commodore 64 @8_Bit | Uploaded April 2022 | Updated October 2024, 12 hours ago.
I wanted to print binary numbers on the Commodore 64 from BASIC. When I didn't find a ready-made solution, I made my own in BASIC. Then I tried to optimize it for speed. Then I coded it in 6510 assembly language on a real C64. But will it benchmark faster?
