The Colossus was setup for desired tests by the operator inserting plugs in sockets and setting switches. This meant the Colossus took some time for each setup to be made and checked for correctness before it could begin working on the cipher text, which was punched on paper tape and threaded around the pulleys of the "bedstead" so that a motor could move it past the photomultiplier tubes which read the cipher text at 5000 characters per second.
It usually took several different tests for Colossus to extract enough analysis statistics to generate a possible group of wheel settings, which would then be tried on a Tunny machine to see if they produced readable plain text German for that message. If they produced gibberish the operator would have to begin all over again on the Colossus, selecting different tests in the hopes of generating a better possible group of wheel settings.

When was the Colossus computer built?
The actual computers called Colossus were World War II code-breaking computers built in 1943 and 1944 in Bletchley Park, Buckinghamshire, England. These were the first true programmable computers, and about a dozen were built.The prototype, Colossus Mark I, was shown working in December 1943 and was operational at Bletchley Park by February 1944. An improved Colossus Mark II was first installed in June 1944, and ten more had been constructed by the end of the war. Unfortunately, the secret nature of these computers meant that their innovations were not available for commercial computer development for many years.*The other computer called Colossus is a fictional artificial intelligence from a 1965 novel (Colossus) by Dennis Feltham Jones, which was the basis for the film Colossus, the Forbin Project in 1970
