A friend of mine just picked up a vintage CD Scanner and can't find
any specs on it.
"Ultra 310" is name on the front panel.
Looks to be a 1950-60's era design/style with a ruddy cyan coloured
case.
Reminds me of a Heathkit kit but he says it is definately NOT a kit.
The are three modular boards in blade sockets on the back right of the
mainboard.
The power connector on the rear is a 2x6 rectangular connector with
five male pins.
No power supply came with it, so he would like to identify the pins
before tinkering with it.

Any help is appreciated.
