Schematics & code for my 74LS-based 8-bit MK1 CPU

Schematics and code for my home-made 8-bit CPU and its companion boards.

During the past month, I designed and built a programmable 8-bit CPU from scratch, out of basic series 74LS logic ICs.

This repository contains pictures, schematics, and code for this project and its companion boards.

The MK1 CPU is composed of several modules, all connected trough a common 8-bit BUS, the status of each module is shown by dedicated LEDs.
