Do any popular Amiga enabled PCI gfx cards still have these interfaces? (They looked a little like a clock port header)




Alex, are we talking about the connector at the top, in the middle, of the card?



My Voodoo3 3000 has one like that.

Edited because....

Hmmmm............. seem to have messed that up. The image URL is:

alexh, he say:
>At the moment I cannot find enough RELIABLE information on the VGA Feature connector, specifically the one on the Voodoo3.

If its any help most of tracks from the pins on the connector that are doing anything seem to be going down towards a small chip called:

S3861Q
9949
RO3968G

This is on a Voodoo3 3000

I've found some diagrams of the Voodoo cards, and the connector in question is called a Digital Video Input Connector apparently.

There's some info and a pin layout here:

So excuse  my ignorance, but in an ideal scenario what might be achieved with the connector?

>However it is looking less like the Voodoo3 has a VGA Feature

Dang.... well, I'll keep my fingers crossed (I'm an Amigan, after all).  Thanks.
