Colossus is back to crack Nazi codes

WW2 cipher breaking machine Colossus will be exhibited at new National Museum of Computing, Bletchley Park. If you are in UK, you better not miss this chance to see early days of hacking.

After 6,000 volunteered man days of diligent work Colossus now sits in the original location of Colossus No. 9 in Block H at Bletchley Park. The public can see demonstrations of how Colossus cracked a real intercepted Lorenz message.

The museum will complement Bletchley Park Trust’s story of code breaking up to the Colossus and allow visitors to follow the development of computing from the ultra-secret pioneering efforts of that time, through the mainframes of the 1960s and 1970s, and the rise of personal computing in the 1980s.

Other planned exhibits in the National Museum of Computing include:

  • working Air Traffic Control station previously installed at West Drayton;
  • the bringing back to life of an ICL 2900 – one of the workhorse mainframe.
