Z3
The third computer designed and built by Konrad Zuse and the first digital computer to successfully run real programs. The computer was ready in 1941, five years before ENIAC.
Zuse began his work on program-driven calculating machines in 1935. His two predessors of the Z3, the Z1 and Z2, were unsuccessful mechanical calculating machines. The Z3 was delivered to the Deutsche Versuchsanstalt fr Luftfahrt (German Experimental Department of Aeronautics) in Berlin and was used for deciphering coded messages. A 1960 reconstruction of the Z3 is in the Deutsche Museum in Munich.
The Z3 used about 2600 relays of the kind used in telecommunications. Zuse wrote and implemented the language Plankalkl on the Z3. Programs were punched into cinefilm.
Zuse built some more computers after World War II, including the Z3's successor, the Z4, which was set up at ETH Zurich, Switzerland.
