Long ago (5 or 6 years) I attempted at programming and made an early working code that displayed Atari logo with color cycling. One switch changed the direction, other switch changed the cycling speed, and B&W switch changed to grayscale. I've spent the last half hour searching but I couldn't find the thread or post with my attempts.
When my eprom programmer went kaput, I didn't have money for a new one and kind of dropped out of programming attempts, then my work on computer became lost so I don't have the original source file or bin.
Any one remember helping me with the switch settings and know where the files may be hiding? TIA
