[OT]: CDC machines featured in "Die Hard"?

Hi folks, Really pushing the boundaries of on-topicness here, but I've just been watching Die Hard (fairly good film as far as "omigod! he's got a gun! blast him!" type films go) and spotted what appeared to be a CDC rack in the background of the "computer room" scenes (well it certainly had "CONTROL DATA" printed vertically up one side). Coloured grey with blue doors and text. Anyone know what they are/were, just for curiosity's sake? I'd check google, but for some reason my router is refusing to forward HTTP (damn NAT keeps falling over).
