This is a replacement controller for the IBM Model M 122 key terminal keyboard running on a STM32F411 BlackPill, intended to act as closely to the 3270 keyboard's functioning as possible while still being usable on a PC.

This is derived from Luke Stanley's handwired/ibm122m keyboard, with my own keymapping and rework of the I/O for the BlackPill. There's also a version for the Teensy++ 2.0, since that was my original design and I still use one on one board, even though I switched to the BlackPill for future-proofing. The Teensy++ 2.0 is not recommended for new designs.
