I have a bus backplane here, very similar to an S100 backplane but the 2x50 connectors use
.1 in spacing instead of .125 and the supply voltages are regulated +5 and +/- 12V.
I also have the power supply; what are they from?
TIA,

it may be for a bus version of the pascal microengine

So no info on the brown box with the open frame supply? I don't see how
that assembly was done, since there does not appear to be room between
the back panel (power) and the power supply to place the board.
or if it is a perspective issue with the photo, the boards that would
fit in there would be 6" x 4" in size, I'd guess.
Appears to be heavier traces down one side, for power, I'm guessing.
The Pascal Microengine had a black and brushed aluminum package, so
isn't consistent with this being a backplane for that. But there were a
number of those sold around w/o enclosures.
Most of the options for the Microengine came out on connectors on the
back of the box, IIRC.
Thanks

There was a bus version. I have cards, but no backplane. from there to scrap dealers.
I don't recall seeing anything that fit with what the guy had in the
photos here with the open frame supply. Could be for the PME, but would
maybe be a refugee prototype or such.
The offices which had some of the development was in Sky Park Circle in
Irvine, colocated with Technology Marketing, Inc.
Some financial people who had dealings with Microdata's founding owned
the building that had both TMI and the WD offices located there.
Albert Wong (IIRC) of the A in AST worked at TMI with a friend till the
ramp up of AST drew him in.
Thanks

FWIW, the power supply looks too professional/commercial to be part of a prototype; it
looks like it's meant to slide into its chassis/cabinet, with a handhold to allow
pulling it out and a spring-loaded latch to lock it into place.
But it's also quite possible that the PS and the backplane don't even belong
together.

What would give you that idea? Neither the number of pins, nor the spacing
of the connector as described in the initial post match...

Should have looked closer before posting. The enclosure (if it is part of

STD bus is smaller with 56 pins; this has 100.

So is this backplane any use to you (or anyone) ?
