	My 3b1 power supply died without so much as a whimper or a blown
	fuse. I am in desperate need of two things:

	1. a working 3b1 power supply or a pointer to a ploace to
	get this one fixed and

	2. the pin out diagram of the main power supply dc connector
	so that I can adapt an external power supply until I get
	a working 3b1 supply.

	Since this machine is used for a communication hub at work I am in
	trouble without it. If you can help, please email me at
	vickeryb at ssc-bee.boeing.com

To expedite, enclosed is a copy of the pinouts (others have asked for these,
too).  As far as replacement supplies, there's the Small Computer Repair Co.,
and some individuals may have extra supplies from the time I located the 1000+
at HSC.
