CoCo Motherboards

This repository contains KiCAD project files that contain schematics and board designs for the TRS-80 Tandy Color Computers that I have recreated. If you want to view and edit these KiCAD projects you'll need KiCAD 7 or higher. You can generate gerber files and order these boards fom your favorite PCB manufacturer.

In order to get the design files you can either use git to clone the repository or you can click on the code button above and download a zip file containing the projects.

To use git, open a terminal and type the following.

git clone https://github.com/qbancoffee/coco_motherboards.git
