        1 +12V +12 Volts DC Output
        2 GND Ground -
        3 Stereo Stereo Sync Output

The stereo sync is TTL and is high when the left eye is on screen.

The best choice for stereo on Indy is using the XSGI stereo extensions
I posted simple sample code for on this group a couple weeks ago. This
works on IRIX 5.2 or later. You would have to figure out how to
incorporate the simple sample I sent into Performer. Performer has
traditionally only used stereo-in-a-window which only works on
RealityEngine and VTX and not Indy.
