Leo III Tape Reels
|
English Electric Leo Tape Reel and Reel Cases dated 1966.
As far as we know, from 1962 (the introduction of Leo III machines) there were only 94 installations of the Leo III. We do not know where our reels originated.
Apart from the pictures of our reel and cases, the remaing show tape reels in Leo III installations.
Key documents on the development of LEO I, the world’s first business computer, have been made available online at http://warwick.ac.uk/leo. The material is part of the archive of John Simmons, statistician and initiator of the LEO project, and includes development reports, memoranda, photographs and a ‘Layman’s guide to LEO’ (a users’ manual), all dating from 1947-1955.
