Post subject:  79-pin connector on a video card
I've dug out this old Compaq video card and from what I can tell it uses an S3 ViRGE/GX chip [ 86C385 ]. It has an onboard 'Feature' [ VESA ] connector... but what I find odd is that there is a 79-pin connector [ at the top of the board ] with traces that come straight from the top-half of the chip, and a 79-pin port [ at the bottom of the board ] that connects with the right face of the chip.

This is really baffling... google didn't come up with anything.

Could this port eliminate an LVDS driver board? I read on a Dutch site that some LVDS LCDs could use the VESA port.


The card uses PCI and has 2MB VRAM. I'll try to do some ASCII art of it and post later.

Anyone at least have a spec sheet for this GPU?

Dude, that's socket & pins for an Memory expansion module for example 2 Megabytes of extra RAM. Matrox and some older ATI cards are made the same way, you cannot use these connectors for anything other than RAM expansion, sorry.

Thanks, mate.

Good to know.
