I have a large collection of vintage Mac's and peripherals, with the largest quantity being the Apple Keyboard II [1]. Archive forums all suggest the Belkin ADB Adapter [2] but that has long since been retired. I would like to make my own, i know instructions exist for a raw passthrough.

I made a adb-to-usb adapter for my AEK2 using a teensy 2.0 and a cut up s-video cable. The TMK and QMK firmware have this functionality, but I used this firmware because it's much smaller and not a "kitchen sink" keyboard firmware:

Unfortunately it's US-ANSI only so my pile of 4 french canadian AEK2s don't work very well with it.
