The Analytical Engine, proposed and extensively prototyped, but never competed, by Charles Babbage was an advanced computing device, the first programmable (and thus necessarily general-purpose) computing device ever. It was entirely digital, but all mechanical; prototyping began in the 1860's. Its program was fixed, and stored on punched cards.
