Commodore also designed a CMOS 6502 core, but AFAIK it
was never actually
marketed as a 65C02.

Tell me more about this. To the best of my knowledge,
Commodore only ever
used NMOS (65xx), HMOS-1 (75xx) and HMOS-2 (85xx) in their computers *save*
the 65, which used the 4510 (modified 65CE02 with two onboard 6526s). HMOS
was, for its part, just a high-speed NMOS manufacturing process (hence H).
I received a data sheet from them many years ago, which I no longer have.
I don't recall the part number they were using. Perhaps I spoke to strongly
when I said that they designed it; it may be that they only wrote a data
sheet in order to guage customer interest. That was before they essentially
stopped selling their chips on the open market.
