Z80 Retrocomputing Developer System. Fixes for my original SBCZ1's problems, inspiration from Grant Searle, the RC2014 project, and some new original ideas. Runs basic tests, am currently coding up a BIOS. May kit it out if enough interest.
Built to accompany the SBCZ1 project. A really inefficient way to implement 7-seg displays but I had a box of these PLCC 8255s sitting around so why not?
My first Z80 design circa 1998, and my first endeavor into PCB fab. Made 3 design errors (all correctable). It still runs today, though it's been abandoned because the hard-wired ROM architecture precluded running CP/M.
A scratch-built Z80 home design built to make use of this wonderful board I had. Ran at low speeds but some stability issues so eventually mothballed.
An old hand-wired SBC I did that's mostly Steve Ciarcia's Circuit Cellar Z8671 SBC.
