For the first time in more than 60 years a Colossus computer is cracking codes at Bletchley Park.
The machine is being put through its paces to mark the end of a project to rebuild the pioneering computer.
It is being used to crack messages enciphered using the same system employed by the German high command during World War II.
The Colossus is pitted against modern PC technology which will also try to read the scrambled messages…
Tony Sale, who led the 14-year Colossus re-build project, said it was not clear whether the wartime technology or a modern PC would be faster at cracking the codes.
“A virtual Colossus written to run on a Pentium 2 laptop takes about the same time to break a cipher as Colossus does,” he said.
It was so fast, he said, because it was a single purpose processor rather than one put to many general purposes like modern desktop computers
