Computador Z3
                        Konrad Zuse (1992).

 

The Z3 computer created by Konrad Zuse was the first programmable machine, fully automatic features used to define a computer. 2200 was built with electromechanical relays, weighing 1000 kg, to a sum is delayed 0.7 seconds and a multiplication or division, 3 seconds. He had a clock frequency of 5 Hz and a word length of 22 bits. The calculations were performed with floating point arithmetic straight binary. The machine was completed in 1941 and 12 May the same year was presented to an audience of scientists in Berlin. The original Z3 was destroyed in 1944 during an allied bombing of Berlin. Subsequently, a fully functional replica was built during the 60's by the creator Zuse KG company, and is on permanent display at the Deutsches Museum. Raul Rojas in 1998 showed that the Z3 is Turing completo.
