Errr, there is -12v. Pin 4. There are two +12v, I've marked three +12v and
two +5v because I think that where soldered, there are either pins on that
connector that are siamesed to accept different types of DIN connector, or
the soldering is crap. I suspect the former.
What the motherboard actually gets is -12v, 2 x +12v, one ground, one +5v :)
