+![IBM Model M 101 ANSI/102 ISO](https://i.imgur.com/DAE3W7g.jpg)
+
+This is a configuration for the QMK firmware for reversible conversion of IBM's Model M keyboards (common 101-key ANSI and 102-key ISO models) from stock, power-hungry controller, to a modern one, running the USB bus.
+Configuration is build for the Atmel AT90USB1286 controller, which you can easily use on the Teensy++ 2.0 board (produced by PJRC).
+Project is heavely based on 2 other projects:
+1. Teensy++ 2.0-based custom Model M controller running TMK firmware ('modelm" by [lmorchard](https://blog.lmorchard.com/2016/02/21/modelm-controller/)); - had a few issues.
+2. Teensy++ 2.0-based custom Model M 122-key controller running QMK firmware ("ibm122m" by [lukexorz](https://github.com/lukexorz)); - had wrong layout for 101/102-key boards and no status LED support.
+
+For this conversion you will need:
+1. Teensy++ 2.0 dev board itself (can be used a different dev board, but it will require some changes in configuration);
+2. Ribbon connectors to connect the membrane to a dev board. Depending on your Model M variation, you will need 1 Trio-mate 16pin connector (6-520315-6 or 6-520415-6) and 1 Trio-mate 8pin connector (5-120628-8 or 5-520314-8), or 2 Trio-mate 16pin connectors;
+3. Full-sized breadboard (without power rails; half-size should do, but full-sized one looks more native) or a PCB to wire everything up;
+4. A bunch of jumper wires;
+5. mini-USB male cable with any USB socket you want to use to connect Teensy inside the keyboard to your PC (I use short mini-USB male to mini-USB female cable);
+6. (optional) Resistors for connecting status LEDs if your LED PCB doesn't have any;
+7. (optional) Double-sided tape to fix USB socket on or inside the keyboard case.
+
+Pins of the Teensy board you should use by default:
+```  
+Columns: 1  2  3  4  5  6  7  8  9  10 11 12 13 14 15 16  
+Pins:    C7 C6 C5 C4 C3 C2 C1 C0 E1 E0 D7 D6 D5 D4 D3 D2  
+--------------------------------------------------------  
+Rows: 1  2  3  4  5  6  7  8  
+Pins: F7 F6 F5 F4 F3 F2 F1 F0  
+--------------------------------------------------------  
+Status LEDs: CapsLock +5V ScrollLock NumLock  
+Pins:        B6       5V  B5         B4  
+```
+
+Please note that some versions of Model M have LED connected with a ribbon cable, and not with separate wires.
