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
