The GHZ is a story about the evolution of The GHZ and the meaning of the acronym. The GHZ is a history of computers as we know it. Computers have changed considerably over the years. In the 50's a computer used for simple calculations would have taken up a football field, and the military needed entire base facilities just to house their computers.
Back in the 50's you didn't work on a computer, you worked inside the computer! Finally in the late 70's and early 80's, the first PC's, the 8088's, where released and back then it would have cost you $1500 for a monochrome monitor, an 8088, and a printer that only printed Ascii and only in black and white.
