I am still not clear on how exactly it works :-( Need to read some more and maybe sit with pen/paper to see how it can calculate and/or evaluate some logic conditionals. Computers are mainstream but the concepts behind computing are still "magic" to most. We automatically assume that it can only be realized in the current complicated form (microchips/architecture layers etc.) and forget that the concept is just a "machine" which you can build in many different forms. Leonardo da Vinci himself had a design for a mechanical calculator - https://www.educalc.net/page/197481/ https://www.educalc.net/page/197481/ and http://www.computer-timeline.com/timeline/leonardo-da-vinci/ http://www.computer-timeline.com/timeline/leonardo-da-vinci/
