Acorn Archimedes Keyboard Converter

This covnerter makes Acorn Archimedes keyboard usable on modern USB computer.

Check these for technical information and resources.

Preassembled converter is available here.

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.
