Does anyone know what this 3dfx card could be?
Initially I thought it could be a Rush but seems like it has more chips (the ones under the heatsinks) than a typical Rush. Perhaps from an Arcade machine?
You could call it Rush 2, it has Voodoo 2 chips onboard. 16 (+16 more on the backside?) chips indicate that 2D chip has 4Mb of memory and Voodoo 2 has 4Mb + 4Mb +4Mb, for FBI, TMU1 and TMU2 respectively.
I must be some kind of standard: the anonymous gangbanger of the 21st century.
I don't even see a Video Bios onboard so I doubt it is a Rush
is this fit on case ? 😀

If it was never designed to be installed into a regular PC, it doesn't necessarily need one.
Also it has complex programmable logic device from Altera, which is probably the core part of "gluing" together this monstrosity.

Can you post a photo of the backside of the board?
Might not want to power it as is, it looks like some TMU pins might be damaged and shorted.
I sent you a PM btw.
I agree it is possibly intended for an arcade machine.

Just looking at it that's my guess too, Ive seen a few Voodoo 3 1000 cards that were also missing the Vbios as they were intended for slot/poker machines and didn't need the vbios to function.
Not sure if there is a way to adapt such cards for the PC but I doubt it.
Besides arcade it might be a card for simulators? I was browsing through Archive.org and found this but couldn’t really find direct references to this card.
Before powering it up please check the legs on the 3Dfx chips. It might be distortion on the photo but to me it looks like they aren’t straight and might short out or lack connectivity at all.

And the rest of us would be carousing the aisles, stuffing baloney.
Simulators are probably more like it. I don't see why would an arcade cabinet require a sophisticated board with VRAM memory and Altera MAX chip.

Tell me more, the video poker machine that's been hanging around on local FB marketplace suddenly got interesting.
Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.
What's the other top connector at the back? RCA?

You would have to open it up to find out but some of the machines here used a modified V3 1000 16mb or a Velocity 100 8mb, they didn't have a Vbios as the machine boards they were on had their own. (Ive seen both types of card, the Velocity 100 was a bit more common)
Not sure why anyone would want a Voodoo with no Vbios but IIRC some arcade machines also used them, might be fun to go digging and find someone more knowledgeable on old arcade machines to talk to about it.
Thanks, I probably don't need the project, just wondered if you knew offhand the model of the machine.

A lot of them, mostly early Aristocrat models as they are the largest maker here in Australia. As for the Arcade Machines you will have to find someone more knowledgeable on them than me.
Here is a Youtube vid on them, perhaps this can shed some light https://www.youtube.com/watch?v=2Zgi17lQSpo
The card is fake.
The pinout of the two visible 3dfx ICs, the V2 TMUs, makes no sense at all.
If we look at the left TMU, at this pin:
It looks like a regular signal.
This is what that pin actually is, a power pin:
If we look at the right TMU, at these two obvious power pins ( thick traces connected to cap):
Those two TMU pins are actually RAM address pins (to which absolutely no one would add two thick traces and a cap):
Also, looking on the two V2 TMUs, their orientation and silk markings, this makes absolutely no sense:
Also, those two 3dfx TMUs would need a 3dfx FBI (or some big ass FPGA replacing it).
A V2 FBI has 256 pins, there is no IC on that board with 256 pins.
These 4 circled ICs were most likely identical, someone removed two of them and "soldered" or glued the two 3dfx TMUs there. That's also why the pins of the 3dfx look so screwed, on all sides.
The board is also using VRAM, which is probably not supported by any 3Dfx accelerator. So probably someone's unfinished pet project or attempt to scam?

It is 100% not an unfinished project. Either a scam or a joke.
This MicroView video card, with its dimensions and memory chips, resembles professional PCI adapters for workstations of the mid-90s, such as the like Tech Source Raptor 1000-2000
