Hey all,
just wanted to present you some small project that I recently started.
I got my hands on an old Apple M0110a keyboard a few weeks ago (found it for really cheap on eBay).
It was in pretty good condition and the original PCB is still working so I converted it to USB using an Arduino Pro Micro.
While that does work it has some minor issues (virtually stuck keys, sudden disconnects etc.) I started to think about if it wouldn't be possible to find a better solution for it.
So I made this:
A fully QMK compatible drop-in replacement PCB for the Apple M0110a
https://github.com/elmo-space/m0110a_usbIt uses the Atmega32a 40-pin DIP package that sits in the exact same location as the controller on the original PCB (right under the spacebar) and the entire PCB is built using THT parts only to keep a vintage look to the board.
So far I have not ordered any prototypes but I will do that soon to test out if everything fits correctly.
The entire project is open source and everyone is welcome to submit improvements
