Could someone out there please tell me what that extra card edge connector is that is on teh top edge of most VGA cards? What can I do with it? Just curious...one of those nasty little things I wonder about whenever I work on the machine and notice it again, but no one ever seems to know why.

My "manual" describes the edge as a "Feature connector: For special applications." There is, however, no mention of what these special applications might be... Anyone else know? Just curious...

I believe the feature connector on the top of all true VGA cards (or so the rhetoric goes) is for external (re: off board) signal handling. Although I've never actually seen this, I am told boards like the IBM 8514/A connect to this connector to provide VGA compatibility. The original 8514/A had no built-in ability to handle VGA modes. I know there are some special purpose video boards out there that do make use of this connector for VGA compatibility... In summary: the average person has no need for this connector. It is intended for special-purpose piggy-back video and multi-media boards.

Well, I use the "Feature Connector" on my Paradise VGA Card to allow the VGA screen to pass thru my Targa+64 Graphics Board. With this configuration, it is possible to run regular VGA, and Hi-Res 24 Bit RGB Targa+ Applications on the same monitor with out switching any cables.

Naw...It's the Video Feature connector. It is used to feed the VGA on to other boards that will do downstream keying as in the Sony 3081 Video Overlay board or Intel's ActionMedia 750 (DVI) boardset. It can also be used in say, portables with built in VGA monitors, as this will provide an internal connector for the monitor instead of using the external connector (and routing a cable back inside :-)). There are other uses too. -- ________________________________________________________________________________ R.
