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

31 Not that wire colors may vary in your cable.

42 You may need pull-up registors on signal lines(`CLOCK`, `DATA`) in particular
43 when you have long or coiled cable. 1k-10k Ohm will be OK for this purpose.
44 In some cases MCU can't read signal from keyboard correctly without pull-up resistors.
50 To compile firmware you need AVR GCC. You can use [WinAVR](http://winavr.sourceforge.net/) on Windows.
51 You can edit *Makefile* and *config.h* to change compile options and pin configuration.
53 $ git clone ... (or download source)
57 and program your Teensy with [PJRC Teensy loader](http://www.pjrc.com/teensy/loader.html).
63 You can change keymaps by editing *keymap.c*.

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