The Z3 was a German electromechanical computer designed by Konrad Zuse in 1938, and completed in 1941. It was the world’s first working programmable, fully automatic digital computer.
The Z3 was built with 2,600 relays, implementing a 22-bit word length that operated at a clock frequency of about 5–10 Hz.
Program code was stored on punched film. Initial values were entered manually.
The Z3 was completed in Berlin in 1941. It was not considered vital, so it was never put into everyday operation.
How was it different from other computers that existed back then?
