The unenhanced Apple //e also used the original 6502 with illegal
opcodes, so this is unlikely to be the reason. If it did work on an
unenhanced Apple //e, it could be firmware changes which cause the
incompatibilty. (Not really a bug.)

This happened with "Kabul Spy" for instance. It doesn't work on the
unenhanced Apple //e, but works fine on all the other Apple ][, //e,
//c versions! The first //e firmware saved the character under the
cursor to a zero page location, which trashes Kabul Spy's RWTS. Later
revisions of the firmware saved it on the stack, so it works fine.

Yes, I think we need a wiki!

Cheers,
Nick.
