Having been sort-of away for awhile (business; teaching classes; and working
the "normal" 25 hrs/day, 8 days/wk :-), I finally today had a chance to catch
up with what's happening at the local electronics stores during lunchtime ...
looks like a Scavenger Hunt for UNIXPC parts!

If you remember, several months ago I "found" pallet after pallet of UNIXPC
keyboards at CSS (aka Weird Stuff Warehouse) in Milpitas, CA.

Today I found UNIXPC power supplies.  Brand new.  Both 3B1 and 7300 models.
In the original boxes from Power Systems, Inc. (12 Tobey Road; Bloomfield, CT
06002).  The 3B1 supplies are in individual cardboard boxes, and the PC 7300
supplies are in slabs of 8 in boxes of 40 (wrapped in pink anti-static foam).

It appears that Convergent's inventory is being scattered throughout Silicon
Valley.  In any event, I hope you're sitting down before reading:

	 QTY       HSC Inventory                             Price Each,
	AVAIL     locator number     Description             Quantity=1
	-----     --------------     ----------------------  ----------

	 1018         10290          3B1 power supply           $9.95

	  245         10292          PC 7300 power supply       $9.50


The GENERAL differences between 3B1 and PC 7300 power supplies are:

	3B1 supplies 5 Amps at +12 VDC, 7300 supplies 3.5 Amps at +12 VDC
	3B1 supplies 300 mA at -12 VDC, 7300 supplies 100 mA at -12VDC
	3B1 supply has a direct cable to the hard disk power connector
	3B1 supply has a power cable for only ONE fan

The 3B1 supplies I found today are EXACT replacements for the production 3B1
power supply; the PC 7300 supplies are a "little" bit different.  Mechanically,
all these supplies are plug-plug replacements.  Following are the stats from
my 3B1, my PC 7300, the "today" 3B1 supplies, and the "today" PC 7300 supplies:

If any of this interests you, contact Mark at:

Be SURE to specify the HSC inventory locator number (at the beginning of this
posting) AND the price to be sure you order the correct part.  HSC has walk-up
counter service, and mail-/phone-order.  They accept VISA, M/C, cash and checks
.
Don't expect to find all of these in the floor display area; most of the power
supplies are in the (back) warehouse.

At these prices, it makes sense to have a spare power supply (or 2 (or 3 :-))
