Thought I'd post this up, after checking it for a project I want to
do, and being unable to quickly find it. Hopefully my formatting isn't
mangled too badly. View this in a fixed-width font. Numbering is based
on what's printed on the //c PCB.

Connect pin 12 to a 470 ohm resistor to ground
Or, a differently formatted version if the format is mangled:
All of top row (odd-numbered pins) = ground
Pins 2, 4, 24, 26, 42, and 44 = ground
Pins 6, 8 = -12 VDC output
Pin 10 = not connected
Pin 12 = connect a 470 ohm resistor between this pin and ground
Pins 14, 16, 18, 20, and 22 = +15 VDC input
Pins 28, 30, 32, and 34 = +5 VDC output
Pins 36, 38, and 40 = +12 VDC output
