In 1994, decades after the last Colossus stopped working, Tony Sale and his team embarked on what turned out to be a 14-year reconstruction project with the bare minimum of information.

Colossus, the code-breaking computer that was kept secret for decades, still generates awe and inspiration.

In this everything you ever wanted to know about Colossus, but were afraid to ask talk, Chief Engineer of the Colossus Rebuild Phil Hayes will describe how the reconstruction of Colossus, which many deemed impossible, came into being despite the secrecy that surrounded it.

He will also reveal what has recently been found by the on going research, and of course, you will be able to see Colossus in action!
