# 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.
