Thanks, guys, for the feedback so far. I've fixed that missing INY in the kernal display loop - this is exactly why I needed it seen on a TV :) I program in caps because I uh... mistakenly thought the assembler didn't handle lowercase mnemonics. I'll fix that. I hate all caps too, but I hate having to shift back and forth even more. If you don't like my excessive editorialising, I'll beg to differ. I plan on releasing this code to people, it HAS to explain whats happening and why. > No. There are 68 *pixels* in the Hblank period, which is 22.667 cycles. Yep, thanks for that one. Shows why comments ARE important. >>ENDVB LDA INTIM >> BNE ENDVB > >If you change that BNE to a BMI, and store a 42 to the timer in the first >place instead of a 43, you're in a little better shape if you do overflow. Thanks for that one, too. I misread the manual as saying that it counted to 0 and then counted UP. I've made these changes on http://www.comcen.com.au/~adavie/push/ The new binary is also included here. NOW does it work? Cheers A
