This site and related git repository 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, so usually:

• Pictures of the front & back of PCBs
• Reconstructed schematics created by tracing traces with a multimeter
• ROM dumps
• Any interesting manuals/datasheets

Disclaimer: I don’t make any guarantees on accuracy of the information in this repository. I only do this for learning & fun.
