Apple USB Keyboard
When I wanted to start building another joystick, I thought it would be best to do a keyboard hack over a gamepad or joystick hack. Since Apple's USB keyboards were pretty cheap I picked one up. Well little did know this was not a good keyboard to choose.
A lot of keyboards have PCBs where there are seperate solder points for each key. Well, the Apple USB keyboard does not use a PCB for the key matrix, it uses a two thin plastic sheets. The two sheets lay over each other forming a matrix. I have scanned the sheets and have them online below.
It is technically posible to make this work and I am doing it right now. It's taking a lot of work and is getting expensive, but at least I will prove it can be done (but at what price :-\
