There's an application note at Microchip's website which had details on 
building an ADB device using one of their PIC microcontrollers. The code 
supplied is in PIC machine language, and it deals with building a slave 
device rather than a controller, but the app note has full details on 
the protocols.

`We don't need you. You haven't got through college yet'."
