Forgot to mention...

The keyboard itself is the same on the VT100, VT101, VT102, etc. The interface
circuit on the main logic board is much the same too, so the info in the 
technical manual is of relevance.

If you can stick one of my hand-drawn diagrams, I have reverse-enegineered
the VT101 logic board and PSU board. Keyboard and video you can get from
the VT100 printset, and I couldn't find a mains input bracket to trace out (maybe
sometime) but that is pretty simple anyway. If you want the VT101 board diagrams
just ask me nicely.
