Five boards from the Titan computer at the Cambridge University Mathematical Lab. Titan was co-developed by the Cambridge University Mathematical Laboratory and Ferranti, based on Ferranti's Atlas computer. Titan is seen as the prototype for the Atlas 2 computer.

By 1961 the University of Cambridge were in need of a new, more powerful computer than EDSAC II. However the funds did not stretch to a computer of the specifications required. As a result, Cambridge University purchased the main processing units from Atlas, and then the University and Ferranti jointly designed and implemented a simpler memory system and arrangements for peripheral equipment. Work began on the project in 1963 and came into operation in 1964. The following year staff decided to add a time-sharing facility, and Titan came into full service in 1966. It ran until October 1973.

Titan was the first transistor-based computer at the University of Cambridge compared to the vacuum tubes of its predecessors, EDSAC and EDSAC II. It consisted of six racks, with approximately 300 boards per rack.

This entry is for a collection of five boards. Note the use of germanium transistors and 'hearing aid'-style triode valves.
