Re: VIC 1112 IEEE Interface

Random adventures in vic20 charcell graphics
I thought I'd share a quick basic scratchup that plots a gingerbread fractal on unexpanded vic. The program uses dynamic character cell allocation, starting from 255 and going down (potentially to 0). For informational ability, the first 64 chars are copied from ram during init. 8) http://jbevren.ne...
