Here is the schematic for the latest version of the Z80 Playground. This is the version that I am selling on eBay.
I’ve improved the logic around the peripheral ports so it is simpler. I’ve added an /int button, and there are a few other minor improvements. I’m very happy with this version. It’s the best yet!
These sold out fast!
Personally I’d be more interested in the Gerber files and BOM.
I love putting together these little memories of the days when I could understand an entire computer.
