Thanks for the kind words, everyone!
@Jieren_Zheng it’s an original unmodified 701C keyboard that I connected to a microcontroller. It runs QMK, which is an open source firmware used by custom keyboard builders. QMK Firmware I’ve prototyped the keyboard and trackpoint using breakout boards and some ugly wiring. The final version will have everything baked into a custom PCBA. I’m still trading whether or not I will have separate boards for the different features or make a “mega board” that contains everything (keyboard, trackpoint amp, Teensy, USB-C hub, M.2 breakout, etc).
@Charles_Forsyth I’m glad you didn’t get rid of it! They’re getting increasingly rare. I would be interested in purchasing it from you if you’re willing to sell. The plastic on mine is quite badly damaged in certain areas.
