M0110 to USB keyboard converter
===============================
This firmware converts the protocol of Apple Macintosh keyboard M0110 into USB.
Connection
----------
You need 4P4C plug and cable to connect Teensy into M0110.
Teensy port F0 is assigned for CLOCK line and F1 for DATA by default, you can change pin configuration with editing config.h..
Plug:
http://en.wikipedia.org/wiki/Modular_connector#4P4C
Pinout:
http://www.kbdbabel.org/conn/kbd_connector_macplus.png
1(Black): GND
2(Red): CLOCK
3(Green): DATA
4(Yellow): +5V
Build Frimware
--------------
Optionally edit Makefile and config.h for build options, pin configuration or MCU.
$ cd m0110_usb
$ make
and program your Teensy with loader.
Keymap
------
You can change a keymap by editing code of keymap.c like following.
How to define the keymap is probably obvious. You can find key symbols in usb_keycodes.h.
This is a default keymap for M0110.

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 ... (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.
Arrow Keys
----------
Dedicated arrow keys of the M0110A are transmitting the same scancodes as the keypad but also,
its [=], [/], [*] and [+] keys (hereafter referred to as "calc" keys) are not assigned new
scancodes but, instead, transmit a sequence of scancodes which emulates the [Shift] key press,
followed by the same scancode sequence of the arrow keys!
The problem with that approach is that, while in most cases it's easy to distinguish between
a user-generated [Shift] key event (press or release) followed by an arrow or a calc key and
a simulated [Shift] key event generated upon a calc key event, when the user is typing fairly
fast, it is possible that the two events become indistinguishable, and produce undesired results
-- nothing major, though, just one or two stray characters or cursor movements; it will NOT
format your drives, kill your cat or make your wife run away with the pizza boy.

* 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: the right Alt key(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.
