   Yes, I believe that this is usually possible. Note, however, that
the Atari 8-bits use a modified 6502, the 6502C. I think it does
something strange with interrupts to facilitate the use of gadgets
like the Antic chip. Therefore, I don't believe you can just pop a
65C02 into an Atari and have it work properly.
