The 1954 machine Hamann 300 (so called version A) - semi automatic " ratchet" calculator. Machines like this one used coupling angle between rotating shaft and double sided gear to encode numbers being bit faster and less noisy comparing to pin wheel designs.

This is the coolest thing. I find this more impressive than an electronic computer somehow, because a computer functions by forcing electrons through an abstract obstacle course, whereas this thing is a machine with cogs and stuff that you can comprehend just by looking at it as it functions and then it does something that seems to transcend what a bunch of spinning metal should be able to achieve. This thing is literally a car transmission box, except instead of just making a second thing spin around it does mathematics.

@@Elriuhilu microscopic silicon things are convenient but you can just wire separate components together and get the same circuit. You could even, theoretically, create such simple components with your own hands (disregarding their quality of course). The only physical process they exploit is ability of one current flow to block another current flow. Just like you could control rotation of worm screw with worm gear. Or like water pressure would push a piston that, as s result, would block another pipe. And the rest of all that complicated silicon circuitry is those transistors wired in many different ways. Like a vehicle that consists of functional blocks - engine, transmission, steering system, suspension, which consist of cogs, worms, shafts, belts, pistons etc. The difference between mechanical and electrical devices is that the former manipulate torque and the latter - current. But aside from that, they are one I'm typing all of that not because I like to argue in the Internet, but because I hope that people who appreciate the beauty of mechanics will appreciate the beauty of electricity as well. With time invested, an electrical calculator becomes as simple as a transmission box

I think that idea was largely killed by the wide availability of programmable computers and databases that greatly reduced the number of times someone had to enter a specific piece of data.
