From the project

A Z80 Computer in a EuroCard Format.

NOTE: This Project is still work in progress and not working at this point !

The goal of this project is to understand how computers and operating systems work. This is a collection of hardware and software to create a multi purpose 8-Bit computer with the popular ZiLog Z80 processor as the heart of this project. Everything is contained in a Eurocard Subrack) formfactor because I really like the industrial look to it. This makes it really flexible and easy to expand (and good looking of course). All the parts used should still be manufacured and every PCB is etched at home so everyone can…
