    And just when you think you've heard of all mid-90s 3D chips, here's the Toshiba TC8512 Gouraud Shading Processor:
    SKUs: TC8512G, TC8512YM. AKA "TC8512G/YM". Nicknames seem to be "HSP" or "HSP-1", short for "High Speed Shading Processor" or maybe "High Speed graphics Processor".

    What used it? No idea - possibly not PC hardware, possibly nothing at all ever used it.

    Since I cannot edit my post... I popped into the "Pixel Talk" Discord this evening and someone idling ("PancakePuppy") coughed up this further information:

    - thedodgegarage says that Akebia had a TMS34020-based card called "Stride" with an available Toshiba TC8512 add-on card but can't find any other sources or pictures for that yet.

    - And there's some mention of a company called Division making a VR system based on 80860s and TC8512s.

    So there's your ballpark time period for that Toshiba TC8512 chip, 1990-ish. Not mid-90s. Cool!
