Speaking of the 65C02, does anyone know if replacing the 6502 in a PET
or VIC-20 is known to trip up copy protection on any apps/games? I
know that for well-behaved code, there should be no problems. I'm
concerned about WordPro or some other pirate-fearing program trying
to be clever with undocumented op codes, and not working with a real
65C02.
