Built in 1951, the massive machine is the "oldest working digital computer". It's now been reassembled from parts held by a museum in Birmingham, and is fully functioning again — complete with blinking lights and brilliant whirring sounds. The reboot was attended by two of the three developers — both in their 90s — as well as by the volunteers who rebuilt it."
