The process involves a small amount of soldering, a Teensy USB controller, and a quick flash of the keyboard's firmware to enable the ADB-to-USB conversion of the keyboard's output.

For hobbyists, adapters like the Griffin 2001-ADB iMate are not the only options for converting your ADB keyboard to USB. Recently tech hobbyist Scott Vanderlind found that by adding a small USB controller to the keyboard, he could tap into the device's ADB connection and send it over USB to any modern device, where it works quite well. Despite being an older style, many of these keyboards were quite well-made and if only they had USB connectors instead of their ADB connections they could be put to good use on modern systems. If you are a longtime Mac user who simply could not bring yourself to throw away your old systems, then you may still have an old Apple Desktop Bus (ADB) keyboard such as the Apple Extended Keyboard II lying around.
