Good plan. Have you thought much about the instruction set yet? Any interesting features from existing commercial 8 bit processors you're going to re-implement?
I plan to KISS it as much as possible. The goal is to learn the basics. Maybe after that do more cool stuff in some HDL. Maybe even buy a FPGA :)
I am a further into the development of the CPU then I show in the blog, as such I do have ISA already, but it's constantly changing. The control bus though, is final I think.
