Unisys

A corporation formed in 1986 from the 'merger' (which started as a hostile takeover) of Sperry Corporation by Burroughs Corporation, two unsuccessful vendors of mainframe computers.

Sells data processing services, software and hardware.

After the Sperry/Burroughs merger, one of Unisys' favorite slogans was "The Power of ²". Am I the only one to see a connection with Charmed?

OK, on from conjecture to fact! Among other things, Unisys sells some rather average Personal Computers (PCs). I didn't say "builds" because these boxes are actually made in the Far East by Fujitsu, a corporation better known for producing cars than PCs. However, they (Unisys) also built a fairly cool PC, mostly for the military. I don't know its model name, but it became known as the Desert Storm PC. The case was made of steel and it would continue to function after being dropped from a height of one meter (about three feet).

Unisys, or actually Sperry UNIVAC, built a series of mainframe computers called the UNIVAC Series 1100 (writeup on this later, I promise) running an operating system called OS 1100.
