1 # modelm101 2 3  4 5 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. 6 Configuration is build for the Atmel AT90USB1286 controller, which you can easily use on the Teensy++ 2.0 board (produced by PJRC). 7 Project is heavely based on 2 other projects: 8 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. 9 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. 10 11 For this conversion you will need: 12 1. Teensy++ 2.0 dev board itself (can be used a different dev board, but it will require some changes in configuration); 13 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; 14 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; 15 4. A bunch of jumper wires; 16 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); 17 6. (optional) Resistors for connecting status LEDs if your LED PCB doesn't have any; 18 7. (optional) Double-sided tape to fix USB socket on or inside the keyboard case. 19 20 Pins of the Teensy board you should use by default: 21 ``` 22 Columns: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 23 Pins: C7 C6 C5 C4 C3 C2 C1 C0 E1 E0 D7 D6 D5 D4 D3 D2 24 -------------------------------------------------------- 25 Rows: 1 2 3 4 5 6 7 8 26 Pins: F7 F6 F5 F4 F3 F2 F1 F0 27 -------------------------------------------------------- 28 Status LEDs: CapsLock +5V ScrollLock NumLock 29 Pins: B6 5V B5 B4 30 ``` 31 32 Please note that some versions of Model M have LED connected with a ribbon cable, and not with separate wires. 33 34 * Keyboard Maintainer: [iw0rm3r](https://github.com/iw0rm3r) 35 * Hardware Supported: Teensy++ 2.0 board by PJRC 36 * Hardware Availability: https://www.pjrc.com/store/teensypp.html 37 38 Make example for this keyboard (after setting up your build environment): 39 40 make ibm/model_m/teensypp:default:teensy 41 42 See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information.
