Univac I

Nowadays, personal computers are everywhere. In our homes, offices, and pockets. But until quite recently, there were many different kinds of computers. Commercial computers, scientific computers, supercomputers, workstations. Personal computers have taken over most of the jobs these machines did.

UNIVAC I was one of the first commercial mainframe computers, safely locked in a climate controlled room, tended by specially-trained technicians. If you were around in 1952, this is probably as close as you'd ever get to a computer – looking through the glass into the computer room.
