And you thought your computer was a dinosaur. Recently, the world’s oldest working computer was dug out of storage and restored to working order at the National Museum of Computing at Bletchley Park. The Harwell Computer, also known as WITCH (Wolverhampton Instrument for Teaching Computing from Harwell) is a relay-based computer that was first functional in 1951. From 1952-1957 it was in use at the Atomic Energy Research Establishment in Oxfordshire. It spent its remaining years, until 1973, as an educational tool at Staffordshire Technical College. After that, it was donated to the Museum of Science and Industry in Birmingham, where it has since been in storage for nearly 30 years.
