wanted: peb backplane.. no box or ps required

lmk what you got

 

also would be interested in any technical documentation for this ..physical measurements etc

I know I have one backplane in my garage, kept from tearing down a non-powering up P-Box.

I don't have all the fancy stuff like everybody else, except MS Paint and a triple unit digital micrometer:

 

Two-sided PCB assembly: 1039315-3 (TI marking)

Width: 104.9 mm / 4.1295"

Length: 192 mm / 7.5615"

Card Edge Connectors: 23.8125mm / .9375" center to center

Connectors: 60 pin (30 X 2), .1" spacing, H421021-30 1832 (TI marking)

Eight mount holes (remainder seem to be manuf/assy fixture holes)

48.4 mm center to center on PCB length

98.53 mm center to center across PCB width

If the units don't "convert", it is because I let the micrometer solve for mm and inches. If you want fractional, or any other measurements let me know.

Can part with this one with or without the four, 8" 22-gauge? solid wires still attached for shipping cost.

I would be interested in the one that Greg doesn't purchase, depending on price and shipping costs.

I transplanted a complete PEB card cage to a PC mid-tower case for my PFM512K Geneve in 1996 for doing MDOS software development in Poland (Forth+ 2.0; never released, 1.0 was released early December 1993). It made it there and back a year later without any problems; after adapting to 220 VAC 50Hz, and finding a usable Polish keyboard, that I didn't think would be a problem. The card cage kept the PEB cards well aligned. Don't you think just the connector board without card cage will be hazardous to the PEB cards. Maybe not so bad for SNUG TI PEB cards, due to the card design.

I just know shipping a pbox is cost prohibitive

Yes, absolutely true. Fortunately for me, the company I worked for, paid to ship my full PC mid-tower both ways.

I have a bare board that I purchased from Mike Dudeck a while back that I use as my reference board. It would be pretty easy to do a new layout using it as a template. . .

Any power supply specs somewhere?

The Formorall schematics show the various voltages output from the Power supply, and even show how to convert the US-spec, push-button style PEB to 220V. It is relatively hard to find the 60-pin connectors for a reasonable price though. I have some (and Swim has already spoken for my spares, as he needed some too), but that was a chance discovery for a good price.
