An Elliott 803 Installation
About the seminar
The Elliott Automation company was a pioneer in the development, manufacture, and supply of early UK computers in the late 50s and 60s.
Elliott computers and software were very successful in the technical and universities markets in that period.
This seminar is about some of the events and achievements in developing Elliott Computers in 60s, with talks by people who took part in the original projects. They will describe their personal experiences of writing software and developing the associated hardware.
Lawrence Clarke will introduce and chair the seminar. Tony Hoare will talk on his recruitment to Elliotts in 1960 and his initial work there on sorting, then onto compiler projects and the decision to implement Algol. Jeff Hillmore will follow on, describing his experiences as a member of the team developing Algol 60 on the 803, and then on the 503 and 4120, and how this work led him to move into an academic career.
Others will add to the story.
Dan Simpson was a member of the Algol teams from 1963-66. Roger Dyke joined Elliotts in 1963 to lead the team designing the control logic and writing the test software for the magnetic tape, card readers etc of the 503. He later worked with Jeff Hillmore on the evolution of the 4100 series central processors before being "loaned" to manufacturing to resolve technical and organisational problems delaying the delivery of the 4120 series.
John Deutsch was recruited to work on "design automation" under Tony Hoare and began by writing the initial hardware test programs for the 4100. He moved to the manufacturing division and eventually became chief software specifier in a team implementing a dual computer message switching system.
The talks will be followed by discussion on the topics raised, and possibly comments and stories from other ex-Elliotts staff.
