Pinout for PlayStation power board?

[martianviking]

Does anyone know what the pinout is for the original PlayStation console's power supply?  I'm talking about the connector between the power board and the main system board.  (Specifically this is for model SCPH-1001, but it should carry for the other 7-pin power supplies.)  I'm looking to find out exactly what each of those pins is supposed to carry so that I can replace the power board with something else.

Any info on this?  Google just keeps returning information on spare power supplies for sale.

The wires on the pins (rear to front on PlayStation motherboard, top to bottom in the picture) are:

purple
blue
white
yellow
orange
red
brown

Blue, yellow and red appear to be ground...

I'd tell you what the voltages present on the other pins were, but an accident with some HT appears to have fried my multimeter.

Got my new multimeter!

Right, at great danger to life and limb, I powered up the PS with no cover over the exposed PSU. This is NOT recommended, as on a European PS, voltages in excess of 300V are floating around there.  Having an isolation transformer helps!

Purple = 3.4V - Drop to 0V to reset console.
Blue = Ground
White = 3.5V ALL THE TIME! This line is powerd, even when the PS is turned off.
Yellow = Ground
Orange = 3.5V
Red = Ground
Brown = 7.6V
