Summary
G.E. (Tommy) Thomas working on the Ferranti-re-engineered drum store c1949. The drum shown was used as a prototype, the data stored on it being the first instance of Manchester code. It was then used in the University-designed and -constructed Manchester Mark I computer until the commercial Ferranti Mark I computer replaced it. The drum was subsequently reused by Dick Grimsdale as the memory of his experimental Transistor Computer (November 1953) which was commercialised by Metropolitan Vickers as the Metrovick 950 in 1956.
