If you're talking about the power connector near the front
panel/power switch, marked as "PC", and have this in front of you,
values should be (from left to right):
5 (yellow) = -12 volts
4 (black) = GND (0)
3 (blue) = +5
2 = no connection
1(red) = +12

I have this, but it would be kind of difficult to send a copy to
Italy, and have you pay for the costs.
Don't have it online, and I don't have the time to put all the pages
through a scanner. Would give too many big files anyway.
Cleaning/re-working these would take too big an amount of time.
If you want, I can help you with the repair though, by checking my
schematics with your findings/observations/measurements.
I did this once before, and it got a NMS8280 in Belgium repaired.
I would need EXACT answers to questions to you, for that. Please mail
me if you think it would help.

No problemo. Yust make sure you make the right connections.
(+5 to +5, GND to GND, etc.)
A mistake here can kill your computer in a sec >;-((
