Hi Peter,
We have not any documentation on ICS "plexiglass" board (P/N 72001) but we have all FRENCH documention for the TK-80 board (the small one).
I don't own anymore these cards, they're in the WDA stock, perfectly tidy against moisture and other bugs

.
I sent you a mail few days ago with some tricks to find out the right pinout of the power connector of the ICS board P/N 72001-J Rev. E.
You need a +5, +12 and -5V PSU (an AT/ATX PC PSU could do the job). I think the -12v is mandatory only for the RS232 serial I/O on the optionnal board P/N 1053601-3.
For finding out the power connector pinout, follow the power pin of the microprocessor 8080 with a multimeter in Ohm or continuity test.
Pin 2 = GND
Pin 11 = -5V
Pin 20 = +5V
Pin 28 = +12V
that's it
See you soon
