Anyone else remember the Diamond Edge 3D? Looking at Wikipedia, it was the first consumer 3D accelerator card, long before 3DFX/Voodoo. Apparently some company called "NVIDIA" made the silicon...the "NV1".
Yeah, it wasn't exactly a stellar success. In fact, it sounds like the NV1 almost sank Nvidia. Here's a very illuminating analysis:

As for Diamond, I seem to recall they got out of the VGA card business, a few years later. Perhaps that had more to do with their MP3 player, which was the first of its kind.
