Scored these on Mercari. Impulse buy, can’t really find much info or drivers on them.

Figured they’d be pretty cool for my dual Pentium Pro server.....

Thanks guys!

Looks interesting, but could you post pictures of the pcb's from straight above, closeups of the large chips, markings, stickers, etc. Unless someone's seen these cards before and knows exactly what they are, those pictures won't do much good.
Do the card(s) get detected if you plug them in?

Video cards for high resolution mutil-panel setup with a cable for synchronization.

I don’t have the cards on hand yet. Here’s the only markings that were in the listing images.

I've worked with Barco equipment before for event-related multi-display and projection stuff, so I'd bet you're right on the money.

the big intel chips are probably just PCI-PCI bridges, why they're using external ramdacs might have to do with syncing I guess (hence why both cards are connected)

idk if that simply wouldn't work with the internal ramdacs or why exactly they do it that way, maybe it also has something to do with signal integrity ^^

Not just probably, they are in fact PCI-PCI bridges.

Most likely it was better/easier to synchronize signals with external DACs at that time.

External DACs could support higher resolutions/refresh rates than internal....that might be reason too...

Not only mine graphics cards collection at http://www.vgamuseum.info

They use IBM 220 Mhz Palette DAC , which was used on some S3 Vision 968 cards, so no.
