Does anyone know any early 3D boards for the PC except for the IrisVision? By early 3D I mean pre-1994 and with hardware accelerated 3D (not just 2D operations like the TMS340x0 did). Ideally, I'm looking for hardware that had a SDK that would let you build an 3D app, not just drivers provided by the manufacturer. I know cards based on the TMS34082 could accelerate 3D, but I couldn't find the, apparently free, TMS34082 3-D Graphics Library. I know Matrox did the SM-640, but I couldn't find any information about how to program it.
