After a three-year restoration project at The National Museum of Computing, the Harwell Dekatron (aka WITCH) computer will be rebooted on 20 November 2012 to become the world's oldest original working digital computer. On Tuesday, volunteers at Britain's National Museum of Computing rebooted the Harwell Dekatron -- a 2.5-metric-ton monster from the early 1950s -- making it the oldest working digital computer … The first general-purpose computer (one that could be set-up to tackle any computational problem) was ENIAC, a computer built at the University of Pennsylvania that carried out its first calculations on 10 Dec 1945. The Atanasoff–Berry computer (ABC) was the first automatic electronic digital computer. Wasn’t widely known as the first automatic electronic computer until a lawsuit concluded so in 1973 against the ENIAC. ENIAC was the most powerful calculating device built to that time. More One of the world's first digital computers to replace the handwritten calculations of human "computors" is getting an official reboot that could lead to a spot in the Guinness Book of Records. The 61 year old computer that refuses to retire. Known to be the first automatic electronic digital computing computer; Was designed to solve up to 29 systems of simultaneous linear equations; Was likely the first electronic digital computer for solving math problems. The world's oldest original working digital computer will now go on display at The National Museum of Computing at Bletchley Park in Buckinghamshire.. ENIAC, the first programmable general-purpose electronic digital computer, built during World War II by the United States and completed in 1946.
