Target of this project is USB AVR controller like **ATmega32U2** and **ATmega32U4**. Using this converter you can revive these retro keyboards with modern computer. + +Read README of top directory too. + +Pictures of **M0110 + M0120** and **M0110A**. + + + + + +- M0110A support was contributed by [skagon@github](https://github.com/skagon). +- M0120 also is supported. keys(+ * / and ,) on M0120 are recognized as cursor keys. + + + +Update +------ +- 2013/08: Change port for signals `PF` to `PD` +- 2013/09: Change port again, it uses inversely `PD0` for data and `PD1` for clock line now. +- 2014/06: Change keymaps +- 2015/03: Add support for "International"(ISO) keyboard(keymap_intl.c) + + + +Building Hardware +----------------- +You need [TMK converter] or AVR dev board like PJRC [Teensy]. Port of the MCU `PD1` is assigned to `CLOCK` line and `PD0` to `DATA` by default, you can change pin configuration with editing `config.h`. + +[](http://i.imgur.com/4G2ZOeg.jpg) + +### 4P4C phone handset cable +Note that original cable used with Mac is **straight** while phone handset cable is **crossover**. + +<http://en.wikipedia.org/wiki/Modular_connector#4P4C> + +Close-up picture of handset cable. You can see one end of plug has reverse color codes against the other.

In that case the converter may not read signal from keyboard correctly without pull-up resistors. + + + +Building Firmware +----------------- +To compile firmware you need AVR GCC. You can edit *Makefile* and *config.h* to change compile options and pin configuration. Also `KEYMAP` option can be used to select keymap. + + $ git clone git://github.com/tmk/tmk_keyboard.git (or download source) + $ cd m0110_usb + $ make -f Makefile clean + $ make -f Makefile [KEYMAP={default|plain|intl|spacefn|hasu}] + +Use `Makefile.teensy` instead for Teensy. + + + +Keymap +------ +To create your own keymap copy existent keymap file to `keymap_name.c` and edit it. You can build it like this. + + $ make -f Makefile clean + $ make -f Makefile KEYMAP=name + + + +Debug +----- +You can use [PJRC HID listen](http://www.pjrc.com/teensy/hid_listen.html) to see debug output. The converter has some functions for debug, press `<Magic>+H` simultaneously to get help. + +- Magic combo: `Shift+Option+⌘` or `Shift+Option+Ctrl`(`Shift+Alt+Gui` or `Shift+Alt+Control`) |
