Wilson Mines Company
The 65c02 has advanced stealthily since the Apple II days, and is being sold in record volumes today (hundreds of millions of units per year) at the heart of embedded custom ICs for automotive and consumer electronics, industrial control, and even life-support equipment, the fastest ones running at approximately 50MIPS (200MHz+). It gives good performance considering its simple bus structure and programming model. http://WilsonMinesCo.com is a gold mine of resources to support the 65c02 & family, particularly for workbench and light industrial applications, with relevant articles on hardware and software methods that the non-computer-engineer can understand, plus circuits, tutorials, links, etc., and much more coming as time permits. Small, hobbyist-friendly 4Mx8 5V 10ns SRAM modules are available too.
