When Rockwell licensed the CMOS 6502 from WDC, they
added their bit
manipuation instructions to it. Thus the Rockwell R65C02 has more
instructions than the "standard" 65C02 from WDC, GTE, NCR, and others.
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.
