This thing is bothering me for quite some time now:
I have this hercules dual planar rush and there is an empty hole on the bracket overooking some pads for a 3 pin connector, and it's sure not for an ordinary mini din 3d glasses output, the hole is too small for that and the pads on the pcb are placed differntly as the ordinary mini din for pcb.
Also is clearly visible that all this 3 pads lead through 3 resistors into a chip (that is also not mounted)

Here are some pics, and if you have seen somewhere something similar to a connector that could fit there or any chip of that dimensions leading to any 3 pin gonnector let me know.

S-Video perhaps?

Noup, S-Video also uses mini din connectors just that they have 4 pins.
So S-video would't fit either.

My Hercules card

I don't have better pictures at the moment but first and the second picture show a three pin connector.

I've got a single planar hercules too, but mine is rev. d so it's a bit different.. but anyway the connectors on your card are (from bottom) VGA out, S-video out, composite out, and the 4th missing one is for a 3 pin mini din for stereovision, like i mentioned in my first post... it doesen't fit into my bracket.

For those who don't know... mini din are a type of connector construction, typical usages of mini din connectors are: ps2 s-video and steroscopic devices, just see the size of one of them and you got the point... the hole is too small! :P

I think that it's a spot for a Composite TV-Out, though I maybe mistaken ofcourse ;)

Composit connectors are larger.   :)

My Hercules card has S/Video out and Composit out. I also have the 3 pin connector. 2 Composit connectors on one board would not be logical  ;)

ok clearing out: the missing connector on thandor's board is the stereovision,

The missing connector on My stingray is not a composite because it's too small (the hole on the bracket).

Hay Thandor what is that connector above the S/Video out?

that must be the missing part on St4r4m4m4's card. looks like a Composite Out or a Stereo Out. for the 3D glasses apperatus

That's the composite

...

again form bottom(thandor's card): dsub,svideo,composite,missing stereo

The photo of the card as i see has been taken by an anche that the composite covers the view to the 3rd pad of the stereo, the pads in this case are big and put in a row
Wich is quite different from my triangulary placed pads

then maybe that hole was custom built there by the bloke that sold it to you, maybe to trick the human mind, because that spot is quite obvious for a Composite-out connector right :)

The hole is original, no sign of anything homemade.

oh okay, hmm pretty odd then, it is small in one such way and simmilar to the Composite out, wierd stuff, maybe that there was another type of output that was cancled, who knows.

oh okay good idea on the photo's ;)

I'll make more detailed photo on the connector area on the pcb of both stingrays tomorrow, until then we'll stop discuting

..edit..
Humm well no need to, It is quite clear on my photos, the mini din connectors such as the one of the stereo and the cinch of the composite are huge comparing the pads on my pcb

allready found on what would of been placed on those connectors St4r4m4m4? I still think it maybe used for a Stereo In, for ASUS's 3D Shutter glasses:

just look at the connector next to the VGA-out:

here a GeForce2 GTS Deluxe from ASUS , if you look carefully on the far left of the bracket you can see a very small round black connector aka the VR out put [Virtual Reallity output] ;)

here some more detailed pics of that ASUS GeForce2 GTS with that VR Output:

Top, look at the top black connector:

Hmm I'll check on that one.

I've updated my Post, with better and clearer shots on what I mean ;) I used shots taken from an ASUS V8200 GeForce3 Deluxe card to get the better idea.

on this later model GeForce3 Deluxe the VR-Out put can be seen also:

it's indeed the same type of small hole on you Voodoo-Rush's Backplate and it's placed at the same height as your is, so I think that your strange hole was meant for a VR output ;)

Here shown how the VR is placed in that small out put like hole just to get my idea of the whole thing :) :
