Hi there!
The "stereo" jack is not for audio at all -- rather, it is for a pair
of LCD shutter goggles that work in conjunction with certain monitors
to display a stereoscopic 3D image. This functionality is REALLY
common on higher-end video boards (e.g. SGI, Intergraph, etc), and
apparently was used primarily in computer aided chemistry visualization
and things like that.
I don't have a pair of requisite shutter glasses to try the concept,
but it always seemed kind of chintzy to be used in a high-end setup.
Sort of like a pre-HMD semi-immersive sort of display technology,
although it's still around...
Kind regards,
Sean

Still used quite a bit, in fact -- the effect is very impressive if you have
the right equipment. I have a lab here with a 10' rear-projection screen
hooked up to an SGI Octane2 runninning chemical and biochemical
visualization...really quite impressive, and fun to play with too :) the CAVE
port of Quake supports this kind of stereo mode, which is very fun on a giant
screen :)

It's chintzy virtual reality technology, but by far the cheapest and more
effective than blue/red 3d glasses :) They don't have them on low-end 3d
cards cause the graphics processor has to render the scene twice, once for
each eye, and double the framerate and refresh rate for the same scene. For
instance, to get the equivalent of a 60Hz referesh rate using shutter
glasses the card has to put out 120Hz, pretty intense, especially at higher
resolutions. My old boss had a GeForce with shutter glasses. They worked OK,
kinda flickery, but Unreal Tournament looked pretty cool jumping out of the
screen like that.
I have used really high-end helmet mouted display setups. They were awesome,
but cost upwards of $20K. An Asus GeForce3 Deluxe is around $400-500. There
isn't much of a middle ground :)

Sure there is. You can get a used 3DLabs or Evans & Sutherland

I bought my Visiontek Geforce 3 ti200 yesterday at the Gateway assessory
store for a net price of under $100 ($185 plus a $26 mouse to get over
$199, then $50 instant discount using code BA686, plus $14 tax, free
shipping, and finally a $50 mail in rebate). Or just stop at a SoCal Fry's
for $99 this weekend on a generic version.
