Arduino-based PS2 -> Macintosh Plus keyboard adapter

This sketch allows to use a PS/2 keyboard with the Macintosh Plus. Mapping between PS/2 keys and Mac keys is stored in the keymap.ino file. Sketch uses a modified version of the PS2Keyboard Library --- all the logic except getScanCode() method have been stripped.

Connecting to Macintosh Plus

Get a phone cord with RJ10 plug and connect pin as follows:

  1. Vcc -> +5V
  2. +DATA -> pin 5,
  3. +CLK -> pin 6,
  4. GND -> GND.

The order of RJ10 pins is the same as in the computer connector:

Connecting to PS/2 keyboard

For the Mini-DIN 6 plug, pins should be connected as follows:

  1. +DATA -> pin 3,
  2. -,
  3. GND -> GND,
  4. Vcc -> +5V,
  5. +CLK -> pin 2,
