let me re-phrase that question.

San Francisco Rush
and San Francisco Rush -The Rock: Alcatraz Edition run on Atari's 'Flagstaff' hardware which uses a 3Dfx chipset.

what is the exact 3Dfx board used?

I know for certain that it is a single 3Dfx board, actually an Obsidian board, with 1 PixelFX chip and 2 TexelFX chips.

basicly an enhanced Voodoo1 board with an additional TexelFX chip for single-cycle (or single pass) tri-linear filtering.

what i wanted to know is the model of Obsidian board this is, I can never remember their model #s


and for that matter, a rundown of the Obsidian / 3Dfx boards used in all of those arcade games would be nice

(System16.com doesnt mention them)

Here's what my Gauntlet Dark Legacy PCB(Vegas hardware) has:

Quantum3D Obsidian2 PCI 650-0818-03D
2x 3dfx 500-0010-01 D19744.00 BE (texelfx)
1x 3dfx 500-0009-01 D19228.00 CK (pixelfx)
1x ICS GENDAC ICS5342-3
20x Silicon Magic 100 MHz SM81C256K16CJ-25 (512KB RAM)(8MB texture RAM, 2MB framebuffer RAM)
1x Xilinx XC9572 PC44ASJ9805 Label: 546-0014-02 NP

I also have a NFL Blitz '99 PCB(Seattle hardware), but it's packed away at the moment so I can't get the full info from it.
