   1 M0110/M0110A to USB keyboard converter
   2 ======================================
   3 This firmware converts the protocol of Apple Macintosh keyboard M0110/M0110A into USB.
   4 Target board of this project is [PJRC Teensy](http://www.pjrc.com/teensy/), though,
   5 you can use other board with USB AVR like `ATmega32U4` and `AT90USB`.

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

  14 Connection
  15 ----------
  16 You need 4P4C plug and cable to connect Teensy or other AVR dev board into the keyboard.
  17 Teensy port `PF0` is assigned for `CLOCK` line and `PF1` for `DATA` by default,
  18 you can change pin configuration with editing *config.h*.
  19
  20 You can find 4P4C plugs on telephone handset cable. Note that it is *crossover* connection
  21 while Macintosh keyboard cable is *straight*.

  42 ### Pull-up Registor
  43 You may need pull-up registors on signal lines(`CLOCK`, `DATA`) in particular
  44 when you have long or coiled cable. 1k-10k Ohm will be OK for this purpose.
  45 In some cases MCU can't read signal from keyboard correctly without pull-up resistors.

  49 Building Frimware
  50 -----------------
  51 To compile firmware you need AVR GCC. You can use [WinAVR](http://winavr.sourceforge.net/) on Windows.
  52 You can edit *Makefile* and *config.h* to change compile options and pin configuration.
  53
  54     $ git clone git://github.com/tmk/tmk_keyboard.git (or download source)
  55     $ cd m0110_usb
  56     $ make -f Makefile.lufa clean
  57     $ make -f Makefile.lufa
  58
  59 and program your Teensy with [PJRC Teensy loader](http://www.pjrc.com/teensy/loader.html).

  62
  63 Keymap
  64 ------
  65 You can change keymaps by editing *keymap.c*.

 121 Debug
 122 -----
 123 You can use [PJRC HID listen](http://www.pjrc.com/teensy/hid_listen.html) to see debug output.
 124
 125 The converter has some functions for debug, press `<magickey>+H` simultaneously to get help.
 126 These function is totally undocumented, tentative, inconsistent and buggy.
