Today's picture shows the"Univac", which was a very early version of a computer. A Univac, along with its accessories could easily fill up a large room. In the early Univacs, the programs were loaded onto the computer via large spools of paper, and the paper had holes punched in it, reminiscent of the old player piano paper cartridges. Later, the paper rolls were replaced by magnetic tape, but even then the "readers" were enormous. The video clip below is an early newsreel describing these univac computers.
