Britain's oldest original computer, the Harwell, is being put back together at the National Museum of Computing in Bletchley, Buckinghamshire.

Known as the Witch, it will be restored over the coming months.

It was designed in 1949, first ran in 1951 and performed mathematical calculations at the Atomic Energy Research Establishment in Harwell, Oxfordshire.

Kevin Murrell, director of the National Museum of Computing is overseeing the reboot.
