Well ive been looking for this disk  for over a year now and it just arrived, the card shown came with the disc ,other disc is v3 blue one to compare to

sorry my hands werent to steady, the brown disc has version 1.0 on it, everything else written on it is same as blue disk, the cards bios sticker reads v3 1000 2.15.05

hmm well my Voodoo3 1000 AGP 16MB SGRAM card also has the same Bios read: 2.15.05. So I think that that isn't the case, maybe 3dfx had a change in disk colour or the Blue ones had more stuff on them and that the blue ones were meant for retail packages and the brown ones for oem's, just my suggestion ofcourse ;).

Gary thought it might have shipped oem/gateway or something
