SGI creates a low power cpu for Apple to use in portable devices, eventually in desktops and laptops (no Arm).
And either: SGI launches low budget PC with playstation 1 level 3d graphics as soon as they could compete with win3.1/95, running Irix. Or: A few years after that SGI launches what is essentially the Voodoo 2.
Any way you look at it the only possible future for SGI was low cost mass market devices. Just a matter of picking which one, they picked none.
