Re: TI-H: IBM PC/AT Power supply.
Standard power supply colors:
black = ground
red = +5v (upwards of 20A on 200W supplies..)
yellow = +12v (around 8A?)
Then there are -5v and -12v (about .75A) on the mainboard connectors,
and I think there is a 3.3v wire also.. Go visit AltaVista and ask it for
a PC power supply pinout or something.
