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`.
+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.

-
- M0110A support was contributed by [skagon@github](https://github.com/skagon).
- M0120 also is supported. keys(+ * / and ,) on M0120 are recognized as cursor keys.
Update
------
-- 2013/08 Change port for signals PF to PD
+- 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.
-Connection
-----------
-You need 4P4C plug and cable to connect Teensy or other AVR dev board into the keyboard.
-Teensy port `PD0` is assigned for `CLOCK` line and `PD1` for `DATA` by default,
-you can change pin configuration with editing *config.h*.
+Building Hardware
+-----------------
+You need **4P4C** cable and **ATMega32U4** board like PJRC [Teensy]. Port of the MCU `PD1` is assigned to `CLOCK` line and `PD0` to `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*.

### 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.
