Colossus was the first of the electronic digital machines with programmability, albeit limited in modern terms. The notion of a computer as a general purpose machine - that is, as more than a calculator devoted to solving difficult but specific problems - would not become prominent for several years.

Colossus was the first of the electronic digital machines to feature limited programmability. However, it was not a fully general purpose computer, not being Turing-complete, even though Alan Turing on whose research this definition was based, worked at Bletchley Park where Colossus was put into operation.
