This is a prototype card, such cards were send to some chosen developers. This project was later transformed into Xeon Phi cards, though LRB2, or Knights Corner, still does have texture units, but the video output connectors were missing similar to some nVidia Tesla cards.

So this one has some ROP's? Supports GL/DX etc?

I hope you have drivers/software for it. Xeon Phi DIDN'T work on windows at first, so I suspect unless this can support later Phi drivers (which I don't think support raster operations), you might be a bit stuck in linux? and without graphics? Hopefully its display capabilities can be recognised outside of its Phi co-processor abilities.

Well I never really had many rare nvidia cards. Or even a gf256 for that matter. But I have had just about everything else.
But yes they are rare, manly do to it being a flop, and if I recall a lot of the cards were traded in for 59x0 and 5700 cards.
Back in the day getting one would not be hard, but today they don't come up for sale all to often.
Its one of the few cards on my want list that I'll probably never use. I manly want one for show.

I caved and bought this piece of memorabilia... I had this exact model when it was new back in the mid-90s. Maybe it was because of that, and the IBM PS/1 my family had at the time that I always preferred OEM-type boards for 386/486, as they always seemed to have video and I/O controllers built on to the board that would later become standard on Socket 7 and later, as opposed to traditional AT-style boards where everything was an add-on card... just seemed messy to me.

P.S. Don't tell my wife.

I like to own prestige cards but I like to put them into systems and build entire prestige systems that I actually use.

Ah, sorry, I edited the post to have the picture, rather than the eBay link.

Cool, looks like it has on-board memory instead of the first SIMM slot. Also I wonder what the brown slot is for?

PS. I won't tell

You have to be pretty careless to kill post-2000s hardware. ESD was a major issue with 90s HW though. An anti-static wrist band usually solves that.

Not really, there are a lot more things then just ESD that can kill hardware.
Lighting strike, failed fan, PUS going BOOM and Caps blowing are just a few.
I like rare cards, but I'd hate the idea of using one regularly as something might happen to it.

Yup... which means the board always has a minimum of 4MB of RAM no matter what options you do or do not put into it, and also the board all by itself with absolutely nothing plugged into it other than the CPU is a fully functioning system... but it does also mean that the first SIMM is stuck at 4MB... oh well. I have a couple 4MB sticks of 72-pin DIMM lying around, so I'll probably put three in to make 16MB... that's a pretty good amount of RAM for a 486.

Not 100% sure, but I think additional cache for the CPU.

Is that an ISA Slot 3 Way splitter riser board? Can you remove it and take a photo of what the motherboard looks like without it?

Got this with my most recent purchase. Can anybody identify it? I've never heard of a dual VGA ISA card before. Model number doesn't find anything at all.

Just pop it into an ISA slot computer. If you got an 8088 you might be able to catch the Manufacturer name and some special logos on this slow system. Back in the day some of these had very fancy delaying animations. If you pop this in a P3 or faster with ISA slots you might miss it since these are too fast.

That's the only way to determine it the easy way. There might be some DOS software from back in the day that could read/identify the Make and Model.

My guess is this would have dual output VGA signals on constantly. You'll have to use two VGA monitors or HDTVs with VGA input to confirm. I have a few PCI ones which seem to only switch to one or the other VGA output when plugged in before powering on but I haven't tried simultaneous VGA output. These ISA ones may behave the same way so you'll have to hook up both ports, have both VGA monitors on, and power it up and find out. The handy thing about these cards if somehow one of the VGA outputs die the other one probably should be good to go.

I've never like onboard ram. If it fails you can't remove it or disable it. Usually if onboard I/O fails you can either not use it or disable it and put in a replacement card.

Very odd stuff. Is the 4MB onboard those 8 chips on the bottom near the DIMM sockets?

I don't recall seeing any motherboards with built in RAM. But now that I think about it I think maybe a few of my Packard Bell 90Mhz had some built in memory.

What would happen if you carefully desoldered those chips off the motherboard then would inserting the the memory module still function properly and eliminate the additional 4MB memory to the total?

Bummer I just noticed in the photo it is using a piezo speaker. 😢

🤣 you didn't Stiletto! 😲 😈

The brown slot looks like a PCI slot but it's definitely on the wrong end.

Also looking at the ISA slots the location where it is not spaced towards the edge near the connectors I wonder what kind of case this will go in as you wouldn't be able to use a standard ATX case to house it. The ISA cards will not be flush so you'll need some extension cables to get the audio out of the back plate gaps.

However if you want to go old school which I've done caseless and air cooled. Just get an old motherboard cardboard box and sit it on top of it. Hook up your AT power supply P8/P9, the old 5 PIN DIN mechanical clicky keyboard to PS/2 adapter, PS/2 mouse, video and sound card and power it up. I hope that 4MB memory works. Love that Intel 486DX33 classic Intel logo.

In most cases, the onboard RAM cannot be disabled on some systems which is ridiculous. I have a Packard Bell Pack-Mate 28 Plus that has 4MB onboard RAM that can be disabled via the jumper settings.

Yeah, confirmed it is for additional CPU cache.

This board is for a "slim" case -- the ISA card you see is not a 3-way "splitter", so much as it is really just a riser card. It breaks out from the proprietary connector on the motherboard to provide three ISA slots. The riser card sits perpendicular to the motherboard, and then the installed ISA cards sit parallel to the motherboard. So, unfortunately, no, it will not go in a standard AT or ATX case. But fortunately, I do actually have a case to put it in which provides both the proper mounts and the appropriate horizontal full-height card slots.

I am a little bit afraid that the power supply that the board requires is not the standard AT power supply pin-out. It is the same connectors, but... who knows what Compaq did in those days. I am desperately trying to find a manual for the thing.

If you get that CPU cache installed I'd like to see what that looks like. I don't think any of my earlier motherboards had such a thing. Most were mounted in the dipp sockets. I had a little tool to pry them out. I'm guessing the one you need might be some sort of card that fits into it with Dipp sockets on it or maybe they are soldered to the card?

Judging by the riser card being parallel to the motherboard what does this thing look like in the case? Do you need just the perpendicular ISA splitter for this to work in it? But seeing those are 3 ISA slots you could still use the open style setting on top of a motherboard cardboard box to hook everything up and test. Was the Mouse also proprietary?

Oh it's a Compaq. That does explain a lot of the way it looks. I remember the dread hearing the name back then. I think in some cases compatibles or clones were still regarded being a better choice. Compaq always used their proprietary crap which made it inconvenient. There were a number of those computer companies trying to compete. AST and Everex were popular but I don't think they went proprietary with their equipment to inconvenience the consumer. Televideo used some phone cable type connector for their keyboards so if you lost it you were screwed.

That's going to be a pain if it must use a standard Compaq PSU. I didn't know they would go that far. If you find out it is a standard AT PSU then you could still buy an ATX to AT PSU adapter and get it to work. I'd get a Fanless ATX PSU so it keeps it all silent. I think you can still mount that motherboard in an ATX case if the motherboard holes match. An ISA card might still fit inside the case given the height and you'd just extend the VGA cable and 3.5mm audio connector from inside and route it through one of the rear brackets left open. It wouldn't be the prettiest way to mount it but it would work. You might still have to use some zip ties to secure the ISA cards from dislodging accidentally from the motherboard.
