Pegasus, produced by Ferranti Ltd., went into service in March 1956
The first Pegasus, produced by the UK company Ferranti Ltd., went into service in March 1956, at a time when all of the computers installed in the UK were designed and built in Britain.
Pegasus was noted for its reliability and ease of use. It was the first computer to have a general register set architecture – a feature now seen in most modern computers.
40 Pegasus machines were built by Ferranti Ltd. between 1956 and 1962. Number 25, the only one still working, was installed in a special gallery in the Science Museum, London, in the autumn of 2000. Members of the Computer Conservation Society restored, and now maintain, Pegasus. A Pegasus simulator, running on a PC, is available.
