Which brings us to the question where we still can get 6502 (NMOS, not
CMOS) in the various speed grades (I wasn't aware, that there was ever an
NMOS 6502 faster than 2MHz? And no, the 65C02 is no option for me as it
lacks the illegal opcodes.)

Looks like this market is now all in the hands of people selling
replacement parts for old machines for a ridiculous amount of money?
