I got inspired by the Revision Zero PCB to want to design a 6502 based Amstrad as it might have been. I'm taking inspiration from the Revision Zero PCB and the final CPC464 and using period appropriate parts.
In the zero-th part of the build I state my design goals and choose a prototyping method, and build out the CPU and ROM.
