Leo III Logic Board

One of the many logic boards that would have been installed in a LEO III

The first Leo III was completed in 1961, not long before the company was merged with the English Electric Company, which not only broke up the team that had done so much for the UK computer industry, but also marked the decline of the computer industry in the country.

Incredibly some machines were still in use in the General Post Office until 1982.
