PS/2 keyboard converter for the Model III/4/4P

Fred Jan Kraan has released the schematics for a PS/2 to Model III/4/4P keyboard converter that lets you use a PS/2 keyboard on your Model III/4/4P.

The project can be found on Github.

The project requires an Ardiuno Nano v3, a MT8816, a couple of resistors, and headers for the TRS-80 Keyboard / PS2 Keyboard / Power.

There are no plans to built and sell, do this is pure DIY.
