Harwell Dekatron (WITCH) at TNMOC 🖥️

The history of the Harwell Dekatron is fascinating. In 1951 it was one of only a handful of computers in the world, and by 1973 it was acclaimed the world's most durable computer. Now that restoration is complete it is the oldest original working digital computer in the world - a record that is likely to stand for as long as it continues to function.
