Hi guys. So I recently picked up some stuff from a recycling center, and among the video cards I picked up one has some wierd add-on card.

Here it is:

I googled it but was unable to find any clear info on it. First I tought it was a memory expansion, but it has no memory module, just another matrox chip and some other stuff. The PCB is silkscreen "TV Tuner" but there are no tuner-like parts on it anywhere.

Have you seen one before? What does it do?

Can't read whats on the chips. Never seen this expansion board, only knew about the extra memory board (have one of those myself though I don't know if it works).
Does the expansion board only fit the 2 leftside cards and not the right one?

Whats missing in your collections?

Maybe u can google for the exact Name/Number on the Chips, and what the Chip does.

Maybe the TV Signal is connected to the Card with with the Pin-Rows an the lower left Edge.

I think it's that Matrox Rainbow Runner add-on card.

the board says "Matrox tv tuner" so that's probably it.

🤣! Now that you mention it, don't know how I could've missed it! 😁
I must be getting old 😜

It seems you are correct.

This is how it fits together with the Millenium 2:

It looks identical to the add-on card I have. What does it do?

EDITED - It seems it does hardware MPEG and AVI video.

Thanks for the links! Too bad I don't have the add-on cables. Would have been fun to play with it.

The pinout for the 15-pin connector can be found here: http://www.murc.ws/showthread.php?39623-Rainb … mation-enclosed
It shouldn't be too difficult to rig up a cable for composite and Y/C video input for it.

Thanks. PCI matrox boards are pretty hard to come in my country. They never sold many because they were VERY expensive, so the're pretty rare (here anyway). This was a lucky find indeed. Personally, I'm not too fond of early matrox cards because of poor compatibility with some dos games, but I won't be using these in dos gaming machines (I use S3 Virge cards in those). Image quality at 1280x1024 is superb on the one Millennium 2 I got to test, so I'll use it alongside a pair of voodoo 2 cards in a slot 1 pentium 3 rig.

Believe it or not, Virge cards are not easy to come by either. Retailers here sold the Trio64 alongside the Virge, so people either went for that or for cheaper Cirrus Logic or Trident cards. I know lots of people who back in the day bought a dirt cheap trident card so that they could afford a Voodoo for 3D - and if I would have had the choice, I would have done the same.

They also still sold 486 and 586 machines when the pentium MMX and even the pentium 2 were out - the old socket 3 rigs were enough for office work.

Looks pretty simple indeed. I'll pick up the parts on my next visit to an electronics parts store and give it a shot.

One problem - both cards are DELL OEM Millenium II 8MB, but one only lists 4MB... model number is MIL2P/8I... any ideeas? Memory chips are different as well. Both 60ns, but the one reporting 4MB has SEC 802 chips, while the one reporting 8MB has SEC 749 chips...
