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”.

Hackney was part of the North East London Computer Scheme (NELCS) along with
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
London Boroughs Management Services Unit (LBMSU). NELC/LBMSU continued to
run its systems on its own LEO III/94 – 1967 – 1974. To see photos enter Computer

HistoricTech.com This site is not an online museum and all items are (or were) for
sale. Instead Edd Thomas goes in search of iconic, rare, unique and sometimes just
fascinating pieces that help to tell the story of the global Technology and
Electronics Revolution of the last century or so. It is a story that combines science and
design with social history, and we are happy to sell far older pieces when they help tell
the story of what came after. The simple aim is to help uncover and preserve the
material pieces that matter, and put them in the hands of the people who will
appreciate them the most. Aimed primarily at the discerning collector and institution,
Edd Thomas is relentlessly foraging for new and interesting items to offer. Each piece
is backed up with a level of academic and historical accuracy (as well as market
understanding) that we feel make them great social and economic investments. We
recognise that our expertise is young and growing and we can only hope to succeed
with your patronage and advice. Our buying policy will always be one of quality over
quantity, and in all instances age and financial value are not the defining virtue for our
stock but cultural relevance. This is because the extremely fast pace of technological
change has made some inventions (even from just a few years ago) seem positively
archaic, while others appear timeless. The collection includes for LEO COMPUTERS
the following: 50 schematics and waveforms for the LEO II some of which have been
annotated (One of the schematics looks to be from LEO I). Developmental notes,
notebooks, waveforms, schematics, draft manuals, photos and publicity all for the
LECTOR Auto reader. Booklets, leaflets and notes related to other English Electric
Leo Computers including the KDF9 and LEO III. One or two of the manuals are the
draft provisional copies. Amongst the items noted, (2019) and described are LECTOR
and AUTOLECTOR includingphotos of the Optical Mark Reading forms designed for
the Lyons Bakery ordering application and LECTOR itself. It includes an Advert for
LECTOR published in the Computer Bulletin by EELM in December 1963. See
