If there is such a thing as a 100 or 200Mhz. 6502, it's in the form of 
synthesizable IP for fabrication into an ASIC or somesuch.  There's never 
been standalone silicon anywhere near that speed rating.

A CoCo in an FPGA should be capable of 25-50Mhz. operation without too 
much trouble and you don't need to pay the license fees for it.
