I'm always looking for old video cards made by STB. I spotted this thing, on ebay. It's cheap, and might be of interest to a collector. I've never heard of the Falcon64 chipset. The date on the card says 1995.

No hint of it having 2D acceleration so far.

I would expect it probably does have 2D acceleration of some sort. How good it is, I dunno, but by 1995 2D acceleration was pretty much a standard feature, so I really can't conceive of it not having the capability... hell, even the Trident chipsets had acceleration by then.

Well maybe it's special in being one of the worst video chipsets available for the PCI bus? 😜

Y'know, I've had a random thought bouncing around in the back of my mind. At one point, I had a Techworks VLB card with some weird video chip on it. And I'm thinking, it may have been the Falcon64... Sierra Semiconductor rings a bell there, and some Googling shows that Techworks did make a VLB card with the Falcon64.

Now, the reason I remember the thing at all is because of what a f__king PITA it was. I remember it being quite fast in both Win31 and DOS... when it worked. But I also remember screen corruption, random issues with a good many DOS games, and the fact that I could never get it to work in Win95.

So if that is indeed what I had, it would go a long way toward explaining why nobody's ever heard of the Falcon64 chipset, and why Sierra Semiconductor disappeared from the graphics card business.

Actually, if shipping from Canada wasn't so expensive, I probably would buy it just to screw around with... even if it sucks, it'd be something interesting for the collection.
