Well, it all depends on your definition of "computer"... :-) I myself prefer to reserve that term for things that are programmable, and Turing-complete. (YMMV... :-) So I call things like Colossus and ABC "digital electronic calculating devices" (or something similar). None of which is to take anything away from the incredible job done by Flowers and his cohorts. It was an amazing device, and had a major effect on history. Noel
