   1 M0110/M0110A to USB keyboard converter
   2 ======================================
   3 This firmware converts the protocol of Apple Macintosh keyboard **M0110**, **M0110A** and **M0120** into USB. Target of this project is USB AVR controller like **ATmega32U2** and **ATmega32U4**. Using this converter you can revive these retro keyboards with modern computer.

  13 - M0110A support was contributed by [skagon@github](https://github.com/skagon).
  14 - M0120 also is supported. keys(+ * / and ,) on M0120 are recognized as cursor keys.

  18 Update
  19 ------
  20 - 2013/08: Change port for signals `PF` to `PD`
  21 - 2013/09: Change port again, it uses inversely `PD0` for data and `PD1` for clock line now.
  22 - 2014/06: Change keymaps
  23 - 2015/03: Add support for "International"(ISO) keyboard(keymap_intl.c)
  24 - 2016/09: Unimap support - keymap editor on web browser

  28 Hardware
  29 --------
  30 You can buy preassembled [TMK converter] or make yourown with AVR dev board like PJRC [Teensy].
  31
  32 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`.

  51 ### Pull-up Resistor
  52 You may need pull-up resistors on signal lines(`CLOCK`, `DATA`) in particular when you have long or coiled cable. **1k-10k Ohm** will be OK for this purpose. In that case the converter may not read signal from keyboard correctly without pull-up resistors.

  56 Building Firmware
  57 -----------------
  58 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.
  59
  60     $ git clone git://github.com/tmk/tmk_keyboard.git (or download source)
  61     $ cd m0110_usb
  62     $ make -f Makefile.rev2 clean
  63     $ make -f Makefile.rev2 [KEYMAP={intl|spacefn}]
  64
  65 Use `Maefile.rev1` for TMK converter rev.1 and Teensy(ATMega32u4), instead.
  66

  68
  69 Keymap
  70 ------
  71 To create your own keymap copy existent keymap file to `keymap_<name>.c` and edit it. You can build with `make -f Makefile.rev2 KEYMAP=<name>`.
  72
  73 Or you can edit keymap on web browser and download firmware.

  78 Debug
  79 -----
  80 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.
