Actually, the system you are describing is CrystalEyes which is
manufactured by StereoGraphics (of San Rafael, California;
1-800-24STEREO) and is resold by SGI for people who want a
Stereo-ready SGI box (if you want to retrofit a non-Stereo-ready SGI
box, then SGI refers you back to StereoGraphics).  They also
make equipment that will connect to other workstations and
even to PC's.
