M0110/M0110A to USB keyboard converter
======================================
This firmware converts the protocol of Apple Macintosh keyboard M0110/M0110A into USB.
Target board of this project is [PJRC Teensy](http://www.pjrc.com/teensy/), though,
you can use other board with USB AVR like `ATmega32U4` and `AT90USB`.
![M0110](https://github.com/tmk/tmk_keyboard/raw/master/m0110_usb/doc/m0110.jpg)
M0110A support was contributed by [skagon@github](https://github.com/skagon).
Connection
----------
You need 4P4C plug and cable to connect Teensy or other AVR dev board into the keyboard.
Teensy port `PF0` is assigned for `CLOCK` line and `PF1` for `DATA` by default,
you can change pin configuration with editing *config.h*.
You can find 4P4C plugs on telephone handset cable. Note that it is *crossover* connection
while Macintosh keyboard cable is *straight*.
[![Conection](http://i.imgur.com/vJoVOm.jpg)](http://i.imgur.com/vJoVO.jpg)
In this pic:
1. `GND`(Black)
2. `CLOCK`(Red)
3. `DATA`(Green)
4. `+5V`(Yellow)
Not that wire colors may vary in your cable.
### Pinout
- <http://pinouts.ru/Inputs/MacKeyboard_pinout.shtml>
- <http://en.wikipedia.org/wiki/Modular_connector#4P4C>
![Jack fig](http://www.kbdbabel.org/conn/kbd_connector_macplus.png)
### Pull-up Registor
You may need pull-up registors on signal lines(`CLOCK`, `DATA`) in particular
when you have long or coiled cable. 1k-10k Ohm will be OK for this purpose.
In some cases MCU can't read signal from keyboard correctly without pull-up resistors.
Building Frimware
-----------------
To compile firmware you need AVR GCC. You can use [WinAVR](http://winavr.sourceforge.net/) on Windows.
You can edit *Makefile* and *config.h* to change compile options and pin configuration.
$ git clone git://github.com/tmk/tmk_keyboard.git (or download source)
$ cd m0110_usb
$ make
and program your Teensy with [PJRC Teensy loader](http://www.pjrc.com/teensy/loader.html).
Keymap
------
You can change keymaps by editing *keymap.c*.

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 `Alt+Gui+H` simultaneously to get help.
These function is totally undocumented, tentative, inconsistent and buggy.

* The keymap works with both M0110 and M0110A keyboards. As you can see, the M0110A is a superset
* of the M0110 keyboard, with only one exception: 'Enter' in M0110 does not exist
* on the M0110A, but since it generates a unique scan code which is not used for some other key in
* the M0110A, they are totally interchangeable. In fact, the M0110A is functionally (almost)
* identical to the combination of the M0110 along with the M0120 keypad. The only difference
* (which is causing some problems as you will read below) is that the M0110+M0120 don't have
* dedicated arrow keys, while the M0110A does. However, the M0120 did have arrow keys, which
* doubled as the [comma], [/], [*] and [+] keys, when used with the [Shift] key. The M0110A has
* substituted the [comma] key with the [=] key, however its scancode is the same.
