The National Museum of Computing held an event at its Bletchley Park base on 26 April to celebrate the centenary of Alan Turing's birth. Today (Monday), TNMOC has posted three videos of the event on YouTube, with a total running time of 85 minutes. This adds to videos of related events at the Computer History Museum in California and the Heinz Nixdorf Museum in Germany.
TNMOC's opening section includes the National Physical Laboratory's video covering Turing's design for his first computer, the Pilot ACE, though he left before it was built.
The middle section is a presentation by computer historian Professor Simon Lavington, who looks briefly at the development of early computers at five sites in the UK, and the development of Turing's ideas after his code-breaking experiences at Bletchley Park. (The UK's different development sites led to different commercial computers from Leo, Ferranti, Elliott Automation and so on.)
In the final video, Kevin Murrell explains how NPL's Pilot ACE (Automatic Computing Engine) worked, and demonstrates a software emulator running on a laptop.
The event was the second of three Turing-themed events linking three of the top computing museums. The first, at the Computer History Museum in California on 7 March, was about the influence of Alan Turing on John von Neumann, and vice-versa. The final event, held at the Heinz Nixdorf Museum in Paderborn, Germany, on 26 May, covered Konrad Zuse and his pioneering computers, and compared Turing and Zuse. (The associated video, below, is in English.) The Heinz Nixdorf Museum has a working mechanical Turing machine.
