IBM Model M Terminal with 122 keys

This is the parent directory for all projects that replace the controller of IBM's Model M terminal keyboard with 122 keys and then run QMK on it.

These controllers differ in their use of microcontrollers, connection (mainly USB) optional speakers etc.

Some of them can be bought fully assembled others are do-it-yourself.

Warning - Model M Variants

Not all of these projects will fit into your keyboard!

As the Model M was produced over several years there are many variants of the controller PCB. Check what fits your keyboard before you build/order one.

The variants built for PCs differ in:

PCB size
Connectors (8/12 pin flex, location)
Ground wire connector location

Additionally IBM built Model M variants with 101/102 keys, the space saving keyboard (SSK, 84-key) etc.
