The Zuse inspired Z1 logic gate demonstration set (improved, again) is a free printable 3D model from Thingiverse by fjkraan. This is a new version of my interpretation of the operation of basic logic gates as they could look like in the Zuse Z1 programmable calculator. You can download the STL file from the original listing below and print it at home.

About this model

This is a new version of my interpretation of the operation of basic logic gates as they could look like in the Zuse Z1 programmable calculator. The information is from pages 216-221 in the book described below. The illustrations are from the patent Zuse applied for in 1936 or by the books' author. The original Z1 is designed and build in 1936-1941. The replica/redesign is build by Konrad Zuse in 1989. The Z2, Z3 and Z4 used relays for the CPU part, so mechanical gates are probably not used here. 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 resembl…
