From someone on the chip team: “The IGA one is prob just a sea of gates and not interesting save for the fact that w/o its timing bug, it would have been a killer in the market as it was the first graphics chip using cheap dram vs static ram as was prevalent at time, sloppy engineering by that team killed it.”
