UK National Computer Museum
Located within the Bletchley Park complex in Milton Keynes, Buckinghamshire, is the UK National Computer Museum.
Bletchley Park is famed for the communication work during World War 2, with the National Computer Museum holding its own claim to fame, assisting the Allies in communication decrypting of Allied Communications.
Included in the price of admission (£7.50 for adults, concessions £5 - August 2017) is a twenty-minute informative talk detailing the creation of the Tunny Machine and the Colossus Computer, used to decrypt and decode German messages.
The Museum has recreated the machines, demonstrating the physical size of first programmable computers used to aid the war effort.
Other sections promote Women in Computing, Air Traffic Control, early mainframes, and Classroom learning.
A personal favourite was the many exhibits of computers and devices from the past, remembering devices I owned and machines I pinned for but never was lucky enough to own.
The UK National Computer Museum is well worth a visit for an hour or two, either as part of the general Bletchey Park visit or as a targeted trip down memory lane.
