Hello All -

How about the 65C816S - This is an expanded 16-bit version of the 6502.
It has 16 bit registers and a 24 bit
program counter, and can run at up to 20MHz. It also has a standard 6502
'emulation' mode. This
processor is used in the SNES and the Apple II GS.

This might actually be useful - code compatible, but MUCH faster....
