What does this actually do? You know, this header above the VRAM chips.

So is this the SLI header? The only comment on SLI for the Voodoo 5500 I could find online is here: https://forums.tomshardware.com/threads/voodo … 5/#post-5993173
And it says "No". Then this guy comes along and uses it to make a quadruple SLI that utilizes 4 Voodoo 5500 cards: http://captains-workspace.com/?page_id=17

So what is this header?
What was its intended use case?
What can it be used for?
And why is it not covered in the Voodoo 5500 manual?

Eventually I found the real manual, but it's just as useless as the marketing pamphlet.

Finally, I found the Voodoo 5500 FAQ from 3dfx itself and there it says something that it's for Quantum3D's AAlchemy cards, which enables cross-board SLI for VSA-100 chips. From what I've gathered, Captain from captains-workspace.com used Quantum3D Mercury Brick module to connect 4x 5500 cards. What would be needed to get just 2 working together?

That looks like a standard VESA feature connector to me.

They were used for DVD decoder cards and such back in the day. More info here: VESA feature connector devices

Read the last sentence on the linked captains-workspace page. It was an April Fool’s joke, nothing more.

Is it even remotely possible that this could be used to create a DVI output?
