MK1 8bit Computer

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

Articles about this project:

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.

DEMO VIDEO (YouTube)

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.

The clock module is designed to allow step-by-step execution; in automatic mode the clock speed can be adjusted from 1Hz up to 32KHz.
The computer programs are stored in RAM and the CPU can be programmed both manually, by inserting binary machine code through dip-switches, and automatically via a USB PC interface.
- The Programming interface is designed to be used in conjunction with an Arduino Nano or the Start9 programming board.
- The Start9 programming board allows the loading of multiple programs stored on an on-board flash memory without the aid of an external computer device.
