16 meg varriants were planned and were technically possible but they never were built, 4MB and 6MB versions of the Voodoo2 were only prototypes, the only ones ever built were the 8MB and 12MB configs and Quantum3D's 24MB sollution the Obsidian X24

hmm this does not come across to the orginal Reso specs of the orginal Voodoo2.
Resolution, Colors, and Refresh Rate for Graphics
512 x 384 x 64K 120Hz
640 x 480 x 64K 120Hz
800 x 600 x 64K 120Hz
1024 x 768 x 64K 85Hz
--> 1280 x 1024 x 64K 85Hz is most unlikely impossible on a Sli set and 800 x 600 x 64K aka 16 Bit is max reso for a single card.
the Reso 1024 x 768 x 16 was only possible in a SLI config but if 1280 x 1024 x 16 was possible I doubt it, never had a Voodoo2 SLi set that could do that since that 1024 x 768 x16 was the max resofor a V2 SLI set

But Man that Game set my good Lord of The Force! this thing must have cost lot's of credits to keep in mind say 600 euro's maybe 700 hehe, never seen these babies in store though.
