"Thanks, guys. Maybe I'll offer this and the other cards on the classiccmp list."
Mike Maginnis
"Interesting! Thanks Hans."

"And yes, Amphenol Centronics was 36 pin, but PC-Centronics was DB-25, while here a DB-37 is shown. For Pre-1986 (before teh first SCSI Standard) it was common to make your own connector, and 37 Pins work quite well for 8 Bit SCSI - The MAC Plus (86-90) had a DB-25 for SCSI.

Also when looking at the 50 Pin ribbon pinhead and the DB-37, it looks as if all active signals are routed and only ground signals where droped. So I still say it's an SCSI Card."

"Given, it's a genuine PC edge, still, Xebec made controllers for both in the early 80s - when PC still ment one or two FD :)"

"Hmm, that Centronics connector seems a bit to short for SCSI. I wonder if that is a printer card... Similar functionality, different electrical signals and timing."

"I would concur with Hans, but its an 8-bit ISA slot connector, not an Apple II connector."

"Looked again at the chips and interface elements. I'm more than before convinced it's an intelligent network card with a AUI connector. Either Yellow cable or 10BASE-T"

"Interesting ... (Everything that follows is just a speculation) This might be one of their 10BORAD36 Cards. DBmV is a unit often used in TV equipment to describe Power Gain/Loss for a certain Signal. Here +15/-8 DBmV may define the signal/noise gain. 3CH may point to the ability to work on 3 chanels at the same time - or at least be able to be tuned to one of these. 10BROAD36 did, unlike 10BASE-T, use a carrier to modulate the data (base band signal), so one coax cable could transport several 'networks' at the same time (while still using yellow cable).

I thought it was a prety fancy idea back then. One cable ring but N times 10 MBit - even with 3+km distance between repeaters or workstations. After all, it got busted by cheap, single chanel, 100m max 10BASE-T :("

"Oops, I didn't see the 'Ungermann Brass' Title, nor it makes perfect sense. this must be some kind of Networkcard. Ungermann and Brass where two guys who left Zilog and founded their own network company. Tyey where among the first to think of networks as a business seperate from the computers itself. I cant tell exactly what kind of card it is, since one of their specialities was 10BROAD - a standard in paralell to 10BASE-T using existing yellow cable but 10 MBit transfer rate and due the use of a carrier, able to bridge some 3+ km between machines/repeaters. It seams as if the card is dates somewhen in 1988, so it could also be just a (fast) 10Bas-T Card. It had for sure a processor subsystem to offload work."

"In Radar Electronics a N-Scope is a display where you can tune/read distance and direction of your target ... well, not realy what this AT-board may do. It would be nice to know what the brownish text reads above the 97762. Looks liek a company name. Also the golden caped DIL name/number (all I see is an intel logo) and even more the one inside the textool socket could help. This might be some CPU (188?) with the visible RAM it could be anything from a fast printer with rastering capability to some fast network interface."
Hans Franke
"Can anyone identify this card?"

"Ungermann-Bass NM5000 card. Stickers on side of shielding read: "PERTBOX: 3CH +15 -08.DBMV", "15068-01 M3D8 064316 9167" and "21317-01""

"I think you're right, Antoine!"
Mike Maginnis
"Thanks for the info. Just seen that on wikipedia (http://fr.wikipedia.org/wiki/Jenga). It seems to me it takes more time to build than to destroy, no?"
