Andrew Dondald Booth (1918-2009) PhD wrote a number of articles during the early 1950's about the design of circuits for computers and about the computers at Birkbeck college Electonic Computation Laboratory.
- Designed the A.R.C. (1947-1949), an Automatic Relay Computer. Some more details about it can be found in an A.D. Booth paper from 1949, presented by Kathleen Britten (later Booth), who worked with A.D. Booth on several of his computers (he built them, she programmed them). The A.R.C., or ARC, initially used a Booth-designed nickel-covered 2" brass cylinder with 21 data tracks and one clock track, which could store 256 20-bit words.
- Produced the All Purpose Electronic Computer (London) in 1952. The APERC was one of the APE(X)C series of machines, where (X) stood for 'sponsors name'. The Norwegian NUSSE computer is modelled after the APE(X)C.
- Came up with Booth's Algorithm in 1950, for multiplying two signed binary numbers in 2's complement.
