The Atlas Computer of the University of Manchester, England, became operational in 1962, as a joint development between the University, Ferranti and Plessey. It was arguably one of the world's first supercomputers, and the fastest computer in the world until the release of the CDC 6600. It was said at the time that whenever it went offline half of the UK computer capacity was lost. It was a second-generation computer, using germanium transistors.
