Attached is a advert for a 1999 "the area 51" I was 13 at the time and wanted one so badly I begged my parents to buy one as our next family PC. I didnt get one! Now I have the means to build one. As you can see from the advert the system had both the Voodoo 3 and a Nvidia Riva TNT2 in one system and would "switch" between the two via a toggle switch. I would like to know how this worked or if anyone has one they can send me pictures of. Looking forward to recreating a classic Alienware rig. Thanks for any help received.
