Well the 6501? 6500? had to change to the 6502 because the earlier

Actually, didn't the Apple 1 have the PCB
layed out to use either a 6800
or a 6502 (2 40 pin DIL positions). You'd have to change the firmware too
of course. but I thought I read that the 6502 was the lower cost option
that everybody actaully used (for suitably small values of 'everybody')
but a 6800 was possible too.
I noticed on some TV show that showed the Apple I board close up, a socket
with a "6800" label next to it. Thought it was interesting, but didn't
give
it much thought beyond that.
