Zuse Z1-Z2, Z4 type memory cell demonstration set

prusaprinters

This is my interpretation of the operation of a single bit of memory as used in the Zuse Z1 and Z2 programmable calculators, and later for the Z4 computer. Most information is from pages 218-221 in the book described below. The original Z1 is designed and build in 1936-1941. The replica/redesign is build by Konrad Zuse in 1989.The original described parts are simple metal strips and a pin (red, blue, yellow and middle gray parts), I added the guides and end stops. In the actual machine the parts will be different and integrated. This model is only to demonstrate the principle, not to resemble the original (destroyed) or replica (Deutschen Technikmuseum, Berlin, Germany: https://sdtb.de/museum-of-technology/exhibitions/1256/).Die Rechenmaschienen von Konrad Zuse/Hrsg.: Raul Rojas.
