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)
