For more information about LEO and efforts to preserve surviving machines, please visit www.leo-computers.org.uk. Peter Byford, chairman of the LEO Computers Society, said: "The LEO Computers Society was founded some 30 years ago to keep the LEO name alive and ensure that the pioneering work that LEO carried out in those early days is fully recognised by future generations. Sadly there is very little of those LEO computers surviving, although both the Science Museum and the National Museum of Computing at Bletchley Park have displays of LEO artefacts.
