Ok, so I found a bunch of 3Dfx datasheets here http://ohwc.narod.ru/video/3dfx.html, but cannot find any pinout information of the 3Dfx chips themselves, at least not in a diagram. Could someone point me in the right direction for finding them?

Old FPGAs are not supported in current versions of Vivado/ISE/Quartus etc, which means you'll probably need to find a license (or maybe even a dongle) for the old tools, and run the thing in a VM. A cheap Spartan 7 is most likely up to the task, and you can use the free version of Vivado. The FPGA …

I too would like to find some 125MHz EDO ICs. Only 100-110 seem to be available. The main IC under that heatsink is an FPGA. I will probably have to write my own code then for the AA module, which wouldn't be bad, since I have custom SLI algorithms planned. Hopefully old FPGAs (or FPGAs at slower …

The Digital marked IC is a PCI to PCI bridge. You don't have to use exactly that one. The ICS ICs are RAMDACs used for VGA output and also clock back the 3dfx ICs. Oh ok, that makes much more sense now. Thanks for the info. I will probably try to source a different chip that has more information on …

To add on to what you said anthony about the left side of the 200SBI, I notice that on a few of the other Quantum3D cards, I see a chip from DIGITAL "21-43925-02" (dc1030e). I see this on the 200SBI, the 200SB, and the X-24 (may be on a few others too). However, I cannot seem to find these on any …

I like the enthusiasm but starting out with a project this big you're likely going to be frustrated really soon and just abandon everything. This 200sbi card is not much complex on its main part, 2 voodoo2 in sli and pci-pci bridge. Easy to replicate. But the left side of the board is quite …

Dear fellow vogoners, I have decided to source old 3Dfx voodoo 2 parts, along with the ICS chipset and required EDO RAM in order to create my own version of the Quantum3D Mercury Brick. This version would not only retain Voodoo 2 compatibility along with the 8x Anti-Alias sampling of the Mercury …

I think that the most logical path is rather than reverse-engineering the VSA-100, I will likely build my own version of the Quantum3D Mercury Brick using 3Dfx Voodoo 2 parts, along with writing special drivers to allow it do more advanced SLI scaling (each card has 2 voodoo 2 chipsets on-board, …

The specs to "3dfx Napalm", which was the codename for the VSA-100, were leaked around the same time as (or even included in?) the big 3dfx leak of 2003.

Best thing is not recreate the VSA-100 with bugs, make a revision 2 of this that will work properly with PCI 2.1, AGP 2x or 4x and another for PCIe and revise the chip to work with 64MB 128bits. 4x the texture and render processor as well then give option of 4 chiplets on one silicon die to allow …

I really just want a fast 3DFX card with support for higher resolutions, which an enhanced voodoo 2 might be able to do. I also would like the voodoo 2 to support more than 2 cards in sli. I'm really not trying to be a dick or nay sayer here but what would that card really be good for? Most Win9x …

isn't the original voodoo or the voodoo 2 a far more realistic target? also probably more useful? and it would open the door for changes like higher clocks that would be impossible with OG hardware, and that could be fairly interesting. still, this is far beyond my level, and sounds really complex. …

-Anthony has recently come up with his own design of a Voodoo 6000 PCI card using said NOS VSA-100 chips. With the expected amount he estimates the cost for an assembled board to be around USD1500. Prices will be similar for other reproductions. If you have to make new chips or reverse engineer and …

I know it sounds silly, but hear me out. As we all know, 3DFX went belly-up in 2000 and then was bought out by nVidia, who we know know as the king of card shortages. Anyways, by that time, 3DFX released chipset and reference board design information (if I recall) for the Voodoo 1, 2, and 3 (and …

I've tested it a lot with DK3D and SW but not with RotT yet. That's probably why I didn't know about that bug until now. Which songs exactly are you having issues with? I might be able to tweak the offending instrument's frequency or fadeoff or something to bring it back in line with GM standards. …
