It's just a nice hobby. (Well, in theory for some people it might be usable for learning 6502 assembler which still is a skill that's requested by employers). > You'd gain about 78000 cycles per second. > > (5 per scan line, about 312 scan lines in total, 50 frames/sec) > > And yes, I know it wouldn't be a lot, that's why I put a ':)' behind > it. I wasn't too serious either, it's just an interesting discussion topic :) -- (\_/) Copy the bunny to your mails to help (O.o) him achieve world domination.
