03:The 6502 is a CISC 8 bit CPU. We'll be implementing it as a synchronous bus FPGA module. It was widely successful, including two implementations by this very project.

And yet, I'm rebuilding it. In fact, I'm fitting a whole new architecture to it. Why?

I'd like to thank my Patreon BBC Micro level supporter, Yehuda T. Deutsch.
