Computing is focused on the historical aspects of early electronic computers.

In 1991 we built the world's first complete Difference Engine No. 2 from plans drawn up by Charles Babbage in the 19th century. In 2000 we built the machine's printer and added it to the Engine.

The Difference Engine No. 2 is surrounded by other Babbage displays, including a portion of the unfinished Analytical Mill and half the great man's brain!

Another fascinating large object in the gallery is the 1956 Ferranti Pegasus – the oldest working computer in the world and one that is switched on and run regularly to the delight of visitors.

A line of wall cases behind the Pegasus detail the early timeline of computer development and also display a selection of calculators and adding machines.
