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:

Vcc -> Vin
+DATA -> pin D5,
+CLK -> pin D6,
GND -> GND.

Connecting to PS/2 keyboard

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

+DATA -> pin D3,
(not connected),
GND -> GND,
Vcc -> +5V,
+CLK -> pin D2,
(not connected)

Arduino-PS2-Mouse-to-Amiga-Adapter

Connect a PS2 (or compatible USB Mouse) to an Amiga

You will need:

Arduino (Nano/Uno/Mini/...)
PS2 Mouse (or USB mouse that can be used with an usb-to-ps2 adapter)
Female DSub9 (to plug into the Amiga)

Connect:

  PS2 Mouse         Arduino Pin
  CLOCK              D11 
  DATA               D12
  5V                 5V
  GND                GND
  
  DSub9 Female Pin   Arduino Pin
  1                   D2
  2                   D3
  3                   D4
  4                   D5
  5                   D8
  
  6                   D6
  7                   5V
  8                   GND 
  9                   D7

Firmware

Upload the INO to the Arduino

Usage

Double-Check ! Connections ! Plug into Amiga and use your PS2 Mouse on the Workbench ...
