Description
This 5 chip Z80 single-board “computer”, is a very simple Z80 based “controller” with 8255 for I/O plus a “Z50Bus” expansion connector. I created it to kick-start my Z80 experiments – breadboarding is fun, but sometimes you want the basics to “just work” so you don’t have to troubleshoot loose wires 🙂
Features an option to use a local crystal-based oscillator or oscillator module. There is an onboard selector to choose between 27c256 EPROM and 28C256 EEPROM.
You can find almost all the components to build this computer in my webshop.
