I appreciate getting your assortment of vfo files to try. I also got one from
Svend Tang-Peterson that allowed me to drive the 24 inch SGI monitor to 92 hz
at 1280 by 1024 before crapping out. I will pursue getting a monitor with
better horizontal frequency specs to attain less flicker in stereo mode.
You asked what I'm working on. I am using Iris Performer to create the latest
generation of Rover Control Workstation software to drive the next Mars Rover
(named Marie Curie) on Mars in 2001. I wrote the previous version using Open
Inventor and got to drive Sojourner around during the Pathfinder Mission in
1997. I can give you more detail on why I'm using stereo for this via email
if you want.
