Analytical Engine
From Computer History Wiki
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.
