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 -> Vin
2. +DATA -> pin D5,
3. +CLK -> pin D6,
4. GND -> GND.

Connecting to PS/2 keyboard

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

1. +DATA -> pin D3,
2. (not connected),
3. GND -> GND,
4. Vcc -> +5V,
5. +CLK -> pin D2,
6. (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:
