When I was 12 I took the Commodore VIC-20 Programmer's reference guide to spain on vacation (!) for 2 weeks. I figured out how to program assembly and hand-assembled a short program to rapidly toggle the screen color from black-to-white. Hmm if I try real hard I can probably recreate it here:
169 0 141 15 144 169 1 141 15 144 76 0 32 Anyway, when I got home, I tried it out. It changes the screen color, but then crashed because of a mistake in the loop instruction. That was definitely an AHA moment - realizing how CPU's work. |
