Reverse engineered Apple II products

This repo contains information about various Apple II hardware that I've seen and decided to reverse engineer. For each piece of hardware I try to include as much information as possible so that the hardware could be cloned if necessary.

This repository hosts a github page that can be viewed here: https://markadev.github.io/AppleII-RevEng
