======================================
This firmware converts the protocol of Apple Macintosh keyboard **M0110**, **M0110A** and **M0120** into USB. Target of this project is USB AVR controller **ATmega32U4**. Using this converter you can revive these retro keyboards with modern computer.
-Pics of **M0110 + M0120** and **M0110A**.
+Read README of top directory too.

- 2013/08: Change port for signals `PF` to `PD`
- 2013/09: Change port again, it uses inversely `PD0` for data and `PD1` for clock line now.
+- 2014/06: Change keymaps

-### 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 that case the converter may not read signal from keyboard correctly without pull-up resistors.

-Building Frimware
+Building Firmware
-----------------
To compile firmware you need AVR GCC. 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 -f Makefile clean
- $ make -f Makefile
+ $ make clean
+ $ make
+
+To select keymap use `KEYMAP` option.
-and program your Teensy with [PJRC Teensy loader](http://www.pjrc.com/teensy/loader.html).
+ $ make clean
+ $ make KEYMAP={plain|spacefn|hasu}
Keymap
------
-You can change keymaps by editing *keymap.c*.
