ps2-to-xt-adapter

=================

When I bought an ancient IBM 5150 without a keyboard, I first assumed that I could just use one of my old PS/2 keyboards. Well, I learned that this is not true... So I built a small adapter that lets you use a PS/2 keyboard with an IBM 5150 or 5160 (XT) computer. It was a great learning experience :-)

How to build the adapter

------------------------

Building the adapter is quite simple. All you need is:

1. a 5-pin DIN 41524 plug 

2. a PS/2 socket

3. an ATtiny85 microcontroller (optionally with socket)

4. a prototype board

Solder the PS/2 and DIN 41524 connectors according to the schematics and adapter.fzz

Use the Arduino IDE to build the code and upload it to an ATtiny85.
