A number of cryptanalysis projects were developed in the UK during the postwar years 1945?1955. One of the most significant of these was Oedipus, a special-purpose rapid analytical machine using novel digital storage. Oedipus was developed by GCHQ and the UK companies Elliott and Ferranti. Oedipus contained a large semiconductor associative memory, a magnetic drum with on-the-fly searching, and a high-speed RAM cache. Its history has only recently been made publicly available.
