The V stood for versuchsmodell which meant prototype, but Zuse later changed the V to a Z after the war. Unlike Babbage or IBM who used wheels and gears to represent decimal digits, Zuse relied on binary code. Even computers such as the Harvard Mark I and the ENIAC used hybrid code even though they were built later. In Zuse’s design, linear movement represented a one while no movement represented a zero. Although the Z1 was mechanical, it is still considered a modern computing machine because of its use of binary code. The machine program was read from a punch tape and had a cycle of 4 Hz. During the 1980s, Zuse received funding to build a full replica of the Z1 after the original prototype had been destroyed in a bombing raid decades before. The replica is at the Berlin’s Technology Museum. Zuse, along with two engineering students, built the replica. Zuse had to prepare detailed drawings and blueprints of every component and after many years, the replica was completed. The replica was like the original and had trouble working on its own. After Zuse passed away, no one attempted to repair the Z1 replica. …show more content…
The overall function and design was similar to that of the Z1. Although the Z3 had similar functionality to the Z1, the Z3 had more features such as new arithmetic operations and square root operations. The machine was far more dependable and didn’t need constant maintenance to continue operating. Just as early models of the Z1 and Z2 were destroyed during the war, so was the original Z3. The Z3 was later recreated in the 60s by Zuse and some engineers from his company. The remake of the Z3 was done in an attempt to strengthen his patent application, but his application was later rejected like the ENIAC patent application. ( Darius, F. ; Goktekin, C. ; Heyne,
