One of my machines at work used to have one of these, but I don't know too much about it other than maybe that its 3D capabilities are very shoddy at best (i.e. Rage I/II, ViRGE). And I've never seen such a product in Diamond's product lineup either, must have probably been OEM-only.

Some resources here:

According to the site it wasn't till the 9850 that Trident had true Direct3D support in their chips?

Interesting. Well it might not be much use but I had never seen one before so that makes it unusual to me.

In my experience, Trident PCI cards were much more uncommon (though not rare) then the S3 PCI cards.

Just to add, there are also AGP versions of this card too.

Can't find it in Diamond's archived pages, but it appears the card is a Diamond DM975. There isn't that much info on the net about this obscure little chip, but plug it in, try running some D3D games and tell us what happens 😀

I think this one renders everything at 99% transparency, and sucks at fill-rate

^ Being the Blade 3D's predecessor, I would assume so.

Well, looky here:

The VGA part is actually very good, i'd say it's the best part of it.

The OpenGL ICD it ships with is slow and it really sucks. Texture clamping artifacts mainly

at least OA looks decent. sort of. 400x300x16 shot, zoom in to check out the dithering

performance i'd say it's around... Voodoo graphics-ish, perhaps even a bit slower than PCX-2.

I need to try this crappy chipset again. It does work with some newer games (3dmark2001 and UT2004 will run on it, but not well)

It has no problems with Final Fantasy 7.

Trident didn't make the transition from VGA to 3D cards very well. (Some would say even their VGA cards weren't very good, but that's a whole other topic.) It's nice to have one to round out a collection, but not to install in any rig you actually intend to use. Most of it's contemporaries were much better performers so you'd be much better off choosing one of them for every day use.

Does the Bt chipset mean that this card can do video capture somehow?

I had this cheap PC with a SiS 6326 AGP, It was the first time I ran a game in Direct3D (HalfLife).
The SiS card soon overheated and they gave me the Trident 9750 AGP for warranty. I remember I had to step-back to the software modes with that thing....

Yeah, I don't think I will be trying it out in any of my systems. It doesn't sound like a very good card. A little bit rare maybe but not worth opening one of my cases for. If anybody wants it I will mail it to them for the cost of shipping 😀

timbre would know about it
(cant remember his web site at the mo)
if its rare and you dont want it he may even buy it from you

I have one of these, also never could find any driver that Diamond ever released for it. I ran it with a OEM Trident diver.

I had run some benches some time ago, and while D3D was a bit slow, it look pretty good and everything like textures and transparencies were displayed correctly.

Here's some benchies from MDK's built in benchmark utility. The Diamond DM975 is highlighted.

what are those units?
So it's not a 3D decelerator, at least. Overall D3D performance is still crappy though (i.e. below Rendition V1000 spec)

I have a couple old Diamond driver cd's somewhere which I noticed had drivers for a couple other cards on them. I'll go have a look and see what I find...

Edit:Oh, will need the Diamond name of the card please 😉

As mentioned several posts above, it's a Diamond DM975 😉

Edit:Ok, found one of those Diamond driver disks (why don't I have all driver disks in one place?? 😜), I didn't see your card in it but I'll post a list of what seems to be on this disk:

Diamond SuperDC
DSCD 1.2/98

Viper V330 (riva128)
Fire GL 1000 Pro (3DLabs Permedia2)
Stealth 3D 2000 Series (S3 Virge PCI only)
Stealth 3D 2000 Pro (S3 Virge/DX PCI only)
Stealth 3D 3000 Series (S3 Virge VX (the one that swaaye always mentions 😜) PCI only)
Stealth 3D 4000 (S3 Virge/GX2 AGP only)
Stealth II G460 (i740 AGP)
Stealth II S220 (Rendition 2100 PCI)
Stealth Video 2500 (AT24 (<--???) PCI only)
Video Crunch It 2000 (PCI)
DTV 2000 (PCI)
Monster 3D (should be Voodoo1)
Monster 3D II (should be Voodoo2)
Monster Sound MX100
Netcommander ISDN/EC (some ISDN card so quite irrelevant)

I know I have another one of those Diamond SuperCD's but in general there isn't much difference between them (except some other cards listed, depends how old the driver disk is).

Don't fret if you can't find a Diamond driver for this card. I've read through most (if not all) of Diamond's archived pages and can't find any info or manufacturer-specific drivers for this card, so it's quite possible that they intended this product purely for the OEM channel. Personally though, I prefer reference drivers over Diamond's anyway since they tend to be newer. Fully removing Diamond drivers from your system (including through the registry, at least from my past experience) is quite a pain.
