Mission Statement of The National Museum of Computing

“To collect and restore computer systems particularly those developed in Britain and to enable people to explore that collection for inspiration, learning and enjoyment.”

The Museum

The National Museum of Computing (TNMOC), located at Bletchley Park, is an independent charity housing the largest collection of functional historic computers in Europe, including a rebuilt Colossus, the world’s first electronic computer.

The National Museum of Computing operates independently to the Bletchley Park Trust heritage site, which has its own entrance and charges its own admission fees.

TNMOC enables visitors to follow the development of computing from the ultra-secret pioneering efforts of the 1940s through the mainframes of the 1960s and 1970s, and the rise of personal computing in the 1980s. New working exhibits are regularly unveiled and the public can already view a rebuilt and fully operational Colossus, the restored Harwell Dekatron / WITCH computer, an ICL 2966, one of the workhorse mainframes computers of the 1980s, many of the earliest desktops of the 1980s and 1990s, plus the NPL Technology of the Internet Gallery. In June 2010 TNMOC hosted Britain’s first-ever Vintage Computer Festival.

Funders of the Museum include Bletchley Park Capital Partners, Google UK, CreateOnline, Ceravision, InsightSoftware.com, 4Links, PGP Corporation, IBM, NPL, HP Labs, BCS, Black Marble, and the School of Computer Science at the University of Hertfordshire.
