First post, by Ozzuneoj
What an odd one this is! I've posted about this in a few places, but now that I've got the card I feel like I should make a thread for it. What makes it interesting, to me, is that it's certainly one of the latest ISA VGA cards sold, and likely one of the latest ISA TIGA cards as well. Since the posts about this card are scattered all over vogons, I'm just going to quote and paste them here in order rather than try to summarize all of them. Thank you PC Hoarder Patrol for your help with this card. 😀

It is a Salient Systems AT3000. It has a Sierra Falcon 64 (only ever seen on PCI cards EDIT: And VLB apparently!), coupled with a 175Mhz Ti DAC... and a TMS34020APCM (marked 340x) TIGA processor, on an ISA card with two video outputs.
The only mention I can find of the card is a single line in a .doc file here: http://bigbro.biophys.cornell.edu/internal_in … are_Catalog.doc
Salient Systems Corporation AT3000 TIGA drivers v126.96.36.199 (8/9/96)
Seller says it came from an ADE CR8X system, which Google tells me is a "Wafer Inspection System" from 2002! (Not text searchable, but it is mentioned near the bottom of the 13th page of the PDF).

There are some pics / BIOS dumps? on bitsavers
A search for AT3000 + Salient links to a number of science / research articles, some of which mention it's use in PC-based systems

Those pictures are amazingly clear! Looks like it has 4MB of VRAM for the TIGA and 1MB of FPM for the Falcon 64. Both look to have room for more memory... though there's probably little practical use for an ISA card with 2MB of VRAM and a 10MB TIGA.

They mention drivers, but can't find any trace 🙁

I'm hopeful that the Falcon 64 makes this a fairly decent card. Compatibility for that chip seems decent based on what I found, and unless there is some issue with the implementation on this card, the performance is probably among the best on ISA, simply because it's a much newer chip.
I've tried a few of the usual sites\archives looking for files or directories including at3000 but haven't come up with anything.
EDIT: Found a post from 2007 referring to a usenet post from 1995 that mentions the card...

Salient says it can take 10MB. 😁

Hope you didn't pay full price 😀 😀 😀
$1700 new for this model with 4MB of TIGA memory and 1MB on the Falcon64
I have the card now and I've tested it as best as I can with somewhat compatible Windows 95 drivers from an STB Horizon 64 PCI (also Falcon 64 based), but I could really use the original Salient drivers if anyone can find them. Supposedly there's an "at3000.zip" floating around out there in cyberspace, but I haven't been able to find it.
Windows compatibility is up in the air because I get crashes\corruption when changing resolutions in 98SE, but problems are to be expected when using a driver for a card on a different interface. Performance wise it does run surprisingly well at 1024x768 in 16color mode. Dragging windows around is quite smooth (showing contents while dragging) for an ISA card in my opinion. This is on a totally overpowered PIII 850 440BX system though. Once I get an ISA VGA test bench up and running again, I think we'll get a better idea of how it compares.
Now for some blitting from the back buffer.
