At the heart of the Mark I and Mark I* computers lay a memory system based on Williams/Kilburn tubes. These were Cathode Ray Tubes (CRTs) equipped with the means for reading and writing binary information as small areas of electrostatically-charged p

What was it like in post-war Britain, before the arrival of the modern computer? How, in particular, did organisations carry out calculations and tabulations, analyses and predictions, before high-speed electronics came to their aid? When, in 1948, a

To modern eyes, the programming conventions of the early Ferranti computers seem both primitive and complex, the complexity arising from the fact that coding was based on the 5-bit teleprinter characters. Users were expected to learn the 5-digit bina
