Better yet: go straight to the code on GitHub. I enjoy making people happy by creating/fixing software and tinkering with things 😊įor professional info, please check my LinkedIn profile and SlideShare presentations. Hi! My name is Carlos, but people often call me Chester.

I used a 6K8Ω (the first one I found within the recommended range) and a mini-breadboard to organize the connections. The TMK ADB-USB wiring instructions suggest a pull-up resistor. But I ended up using breadboard jumper wires, because they can be easily plugged on the Arduino and inserted straight into the ADB jack holes. To connect the Arduino to the keyboard, I could have cannibalized an S-Video MiniDIN-4 cable, since ADB uses the same connector. I wasn’t sure that would do the job, so before tearing the keyboard apart, I decided that my first experiment would be an attempt to connect it to my computer. But the hack uses an Arduino Pro Micro (with a little help of the TMK Keyboard Firmware Collection) as a converter between ADB (the interface used by the Apple II GS and older Macs) and the familiar USB, and I only had a regular Arduino (actually, a Leonardo-compatible clone).

My winter holiday plans did not include going outside, so I wanted to build it with parts I already had. More important, I happen to have an Apple Extended Keyboard II just waiting for such an experiment… When I saw this person building a Raspberry Pi inside a vintage Apple Keyboard, I thought it could be a comfortable way to play Apple II games on a TV.
