PS2 Keyboard Interface based on the ATTiny with Arduino framework
This design has not been compliance tested and will not be. It may cause damage to your Amiga. I take no responsibility for this. I accept no responsibility for any damage to any equipment that results from the use of this design and its components. IT IS ENTIRELY AT YOUR OWN RISK!
The main purpose of this design is to provide basic PS2 Keyboard support to an Amiga. It is developed using the Arduino framework to keep the design very simple.
Installed in A600:
Schematics will be published - once drawn. The design is very simple and only basic connections for the PS/2 Keyboard and Amiga are required. For the A600 / A1200 Version (pictured above) I used a NPN with 3 signal diodes forward biased wrt. the keyboard controller inputs to assert the /KBRESET signal.
