wow that's a nice find Gary there is also no hardware to test it with? I mean that DVI connector? cause that would also be great if you had en onl DVI device to test it with

Only wish that was possible .

Just got a note back from the guy who designed this board, it has a V3 chip BTW.

Subject: Just what the heck were you building out there?

Answer: The stuff on the right is a dynamic load to allow power supply testing, and the power supply circuit we wanted to test, for the V5 6K.  Turned out to be overkill.

wow that 5500 AGP Dual CRT is very nice, it also has that Flap behind the AGP connector the same type of flap the Voodoo5 6000 Rev.A1 1500 has


and another thing, I also thought about the extenal power supply plug for this card:


you see that the streched Voodoo3 this card:

it has a white PSU plug abouve the CRT in, and the V56K 2x2 card has traces for that plug

The Force is my powerfull Ally

Yeah thanx Gary, I used to make model planes and hav'n a sharp eye is very important for perfection for the models.

Anyway there is something else also.

The Voodoo3 strech has the layout of a Velocity-100, I'm asumeing it has 8MB 5,5ns SGRAM

here the Velocity 100 and under it that strech V3 circuit test board for V56K. :





I saw this by looking carefully at the traces in the PCB and the layout of the chips themselves.

There are some little differences though in the fron part, the strech V3 circuit test board for V56K had some unknown VRM like chipless space, which the Velocity 100 does not have, the Velocity 100 has it's VRM placed just before the AGP connector, the strech V3 circuit test board for V56K is also missing that chip there also.

I'm not sure if it's a VRM, but it look's like one.

Please note that a few of the shots have a fuzzy spot in the picture, this is due to a defect of my camera which is due to be replaced.



Tom's Hardware also had a mention of the 6MB models, nowhere else on the net have I found a reference. It would be nice if you could scan in that article.

This page shows two 6MB cards in SLI configuration- Note the location of ram for CK and which direction the SLI connector is pointing.

The V2 in my hand is dated 44-97, with the chips dated 46-97.  November of 1997!

In regards to the big PCB with the V3- It's been stated that the reason a V3 chip was used for this V6K powersupply test board was that 3dfx didn't want to burn up any VSA-100 chips in testing.

Perhaps they were in short supply at the time?

Some favorites from the box-



4MB Voodoo Rush board is very cool!



V5-6000 Intel PCB!



Prototype V6k fan set never used- I almost didn't get this one, the seller wanted to hang on to it and there was some hard barginning.



A prototype Voodoo 3 with SDRAM, also note the PCI interface and TV-out. What is intresting is the 3dfx had no plans to sell a PCI V3 version (or so they claimed back in the day)



An intresting prototype- Also PCI but the Voodoo 3 has an external RAMDAC chip like a Voodoo 2!



My favorite of the V3 boards- Fan cooled and running at 183mhz!

I'm only keeping about a dozen of the boards shown, everything else is up for trades or outright sale and a few have already found new homes
