======================================
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.

### 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 Firmware
-----------------
To compile firmware you need AVR GCC. You can edit *Makefile* and *config.h* to change compile options and pin configuration.
