The site is maintained by Pete Wooledge a member of the LEO Computers Society,
who notes (December 2020) “212 LEO II/III Tapes and 1 Tape front at: http://www.vintage-icl–computers.com/icl42
The Museum Collection here is now lucky enough to have 212 of these LEO Computers Ltd Tapes!!!
The separate EEL type of tape turns out to be for the EE KDF 9 computer and not the LEO.
Also the count for the marked LEO tapes was one over making 210 but as luck would have it 2 more
marked LEO tapes arrived making it 212 plus the KDF 9 tape. Some good news is that Delwyn Holroyd and others at TNMoC are to attempt the reading of these tapes when the Pandemic permits.
We all hope that some interesting DATA can be saved from these tapes”.

the boroughs of Haringey and Tower Hamlets. NELCS had emerged in 1966 out of the
London Boroughs Joint Computer Committee’s (LBJCC) that was formed in 1962 and
had developed systems running on a LEO III/94 computer. NELC was managed by the

run its systems on its own LEO III/94 – 1967 – 1974. To see photos enter Computer
