Pinouts and Wirings

Mini-DIN-6P female socket from the front:

                Connector                   AVR pin
                ------------------------------------
  ,--_--.       1: Reset                    PD0
 / o6 5o \      2: NC
| o4   3o |     3: GND                      GND
 - 2o o1 -      4: 5V                       VCC
  `-___-'       5: In(from keyboard)        PD1
                6: Out(to keyboard)         PD3

Target microcontroller is Atmel ATMega32U2 by default but porting this project to other 8-bit AVR controllers would be easy.

Mouse support

Not tested with real mouse but it should work somehow.

I don't have Archimedes mouse to test, try and make a report if you have one.
