Zuse inspired Z1-Z2 logic gate demonstration set (improved)

thingiverse

Here is my interpretation of the operation of basic logic gates as they could be used in the Zuse Z1 and Z2 programmable calculators. The information comes from pages 216-221 in the book Die Rechenmaschinen von Konrad Zuse/Hrsg.: Raul Rojas, which I'll refer to below. The illustrations are from patent Zuse applied for in 1936 or by the books' author. The original described parts are simple metal strips and a pin (red, blue, yellow, green and middle gray parts), I added some guides to make the gate work in isolation. 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/). This is an improvement of a previous design. The book does not mention the type of gate being described, but it appears to be an XNOR. By rearranging parts it can be transformed into an AND gate, and by substituting some parts it becomes an OR gate. These two gates are actually described here. NOTE: nowhere in the literature is mentioned what the Z1 and Z2 gates actually looked like. The 3D-rendered gates shown here are only a possibility, based on a generic description in the patent application. To create an XNOR gate, add another c-d-blech. The definition of a "0" and a "1" isn't consistent with this configuration.
