That's unbelievable!

This is fascinating to watch! Were you able to get it working with 3D Studio for DOS?

I don't believe there was a 3DS driver for this card, either MicroChannel or ISA. I was involved in developing the AutoCAD ADI driver and that supported the 3D extensions for AutoShade and Animator as I recall. I'm not sure what driver interface 3D Studio used, but it wasn't ADI.
