Hi there,

I'm looking for information about the power supply in an IBM PS/2
Model 55 SX. Specifically, I need the pin-out of the connectors
that feed the system board. There are two such connectors with the
following wiring.


	J7:	White		^
		Black		|
		Orange		back of case
		Blue
		Black
		Black
		Black
		Black
		Yellow
		Red
		Red
		Red

	J14:	Black
		Black
		Red		front of case
		Red		|
		Brown		v

I guess black is ground, red +5V, and yellow +12V. The remaining
colors must be -5V (blue?), -12V (white?), POWER GOOD (orange?)
and what else? If you know the exact arrangement, please drop me
a line.

Also, would you know where I could get a replacement power supply
for the machine? The power supply's sticker shows the manufacturer
as Delta Electronics and the model as DPS-90DB. Is this type or an
equivalent supply still available somewhere?

I'd appreciate any help you can provide.

Please reply be e-mail to

	wwitt@smdvx1.intel.com
or
	witt@ucsee.berkeley.edu

Thanks.

Wolf
