Graynomad:
I cut my teeth on Z80 assembler and for years I've though of building a retro board with all my old favourites, CPU, PIO, SIO, CTC, etc. It would be a lot of fun but really, why bother...still the idea appeals all the same.

Same here, Z80 assembler is how I started out. I designed an all in one embedded board that I used in a few projects. Love the Z80 instruction set. I have written multiply and divide libraries too.
