      1 # IBM Model M Terminal with 122 keys
      2 
      3 This is the parent directory for all projects that replace the controller
      4 of IBM's Model M terminal keyboard with 122 keys and then run QMK on it.
      5 
      6 These controllers differ in their use of microcontrollers, connection (mainly
      7 USB) optional speakers etc.
      8 
      9 Some of them can be bought fully assembled others are do-it-yourself.

     11 ## Warning - Model M Variants
     12 
     13 **Not all of these projects will fit into your keyboard!**
     14 
     15 As the Model M was produced over several years there are many variants of the
     16 controller PCB. Check what fits your keyboard before you build/order one.
     17 
     18 The variants built for PCs differ in:
     19 * PCB size
     20 * Connectors (8/12 pin flex, location)
     21 * Ground wire connector location
     22 
     23 Additionally IBM built Model M variants with 101/102 keys, the 
     24 space saving keyboard (SSK, 84-key) etc.
