Customized and Upgraded IBM Model M Terminal Keyboard

This is my early 1990's IBM Model M terminal keyboard. I've replaced the original PCB (that was dead when I purchased it) with a custom board containing a Teensy ++ 2.0. A speaker has been added in the factory location on the bottom of the keyboard. The terminal versions of this keyboard did not come with status LEDs, so I built a custom board with NeoPixel LEDs and bought a new overlay from Unicomp. The LEDs are able to be set to any color or pattern, but will change solid green like OEM when enabled. The keyboard is running the VIAL version of QMK. The source for it and more information can be found on my Github. Below you will find some pictures of the build process. I didn't do a full documentation of the build, but feel free to reach out to me with questions.
