Mr. Staecker, I have complimented your closing remarks before because they are terse, witty, and incisive. You have outdone yourself this time. This channel is a gem. Thank you for making it!

Mechanical computers like this would be great for intro programming classes. We talk about registers, operations, and cpu cycles as concepts and this has them all here literally.

I re-watched it five times before I was ready to continue with the rest of the video. I'm gonna go watch it five more times, right now.

aha! Found it! In a manual for the Muldivo Mentor ( a quick google search should bring up the scan ): page 7 Division by subtraction Example 13: 144 ÷ 12 = 12 Shift carriage completely to right. Set dividend 144 in highest columns of register using the little discs located beside the figure wheels (the setting discs must be moved upwards). You may also begin by setting the dividend in the setting register and then transferring it into the result register by one clockwise turn of the crank hangle. In this instance, do not forget to clear the 1 which appears in column 8 of the revolution register. Place decimal indicator in result register behind 144,000 .. Now set divisor on setting register with leers 9 and 8. **To avoid confusion, a blue spot has been marked at the head of the column in which the highest digit of dividends and divisors may be set.** I hope this helps! :)

Okay you can’t set a dividend or divisor in column 10.

The blue dot could be marking the starting position for square root computations, but I'd put it at the 8th digit. Look up how the algorithm for that works, it's quite fun.

The blue point is marking the leftmost place where you are supposed to put the first number of your dividend in, you can not start at the leftmost position

Great vid!! But that very brief shot of the inside sure left me hungry for more of that. Like how excactly the inner linkages and whatnot are put together. Thanks for making these, and loking forward to seeing more of the machines you got from that find.

My dream would be the double pinwheel machine made for artillery surveyors…it can calculate 2D coordinates given sine or cosine of direction and distance. It can go in opposite directions for NW or SE directions.

WSR-160 or PPK ?

When I was a student, I worked as an assistant chain man for a surveyer. The pro surveys used these machines in the field to calculate their transects. On Frisday afternoons, when all the work was done, we would all drink beer. One of the fun things to do was to set the units big wheel to 1, was see who could count the highest in one minute by turning der krank as fast as our hands could go.

My pop had a Mauser dial bore gauge, a machinist's tool for measuring the diameter of holes with about 0.01mm of resolution. I imagine it's a similar story where they couldn't make weapons after WWI or WWII and switched to metrology.

My first machine which started my collection was one of these but until you mentioned it I had never noticed the blue dot before. I also have absolutely no idea what it is there for!

The older version of the WSR160 doesn't have the blue dot, but a band with the figures 1-10 for the 10 input register sliders. The 9th position in that band is blue, too...so it IS a marker for that position. Which is the left-most position for a division.

What an impressive video. Smart machine!

A calculator of this caliber would definitely be as deadly as a ppk in close quarters combat - the blunt trauma from slamming one of these in the head of ones adversary probably would be quite effective 😉

My father had the exact same model. I loved to play with it as a child. I can't remember the blue dot, but I'll ask my dad about it.

I did see some other models which have the input digits numbered (10 to 1, left to right), where the 9 is blue. It must hold some significance, but *what?*

It marks the position of the 1st digit for division. You can't use the input slider to the left of it, as the carriage can't move that far with its digits. So it made sense for WALTHER to mark that 1st digit's position in a non-disturbing but still visible fashion.

0:50 that guy who used to own the house sure was a weirdo!

i want one so bad! unfortunately i do not have any use for it and it would take up space and money. add to that (hah!) that my first adding machine purchase is probably going to be some monroe machine, on account of family history. but maybe a pinwheel is what i really want.

The pin(wheel) is mightier than the sword. And by "sword" I mean "gun".

are you sure it wasn't purchased on 06 december 1979 (instead of 12 june) with the date being in standard european dd/mm/yy format as used in amsterdam? great video, though, really clear explanaions and presentation, keep it up!

10:46 Right before the footage ends, I noticed that the second-least-significant digit in the counter went from 0 to 9, despite the register bar being shifted to the fifth-least-significant digit. What happened here, I wonder? Was this a temporary "glitch" that fixed itself after the end of the footage? Or was this a genuine mechanical error?

I think you are the first to notice- this video actually has a huge amount of movie-magic funny business. The truth is, my machine actually isn't working properly- the wheels inside are slightly misaligned, and so they usually work fine but often it'll add values into locations when it shouldn't. Much of the footage I used has been doctored to hide this fact- I considered just saying up front that the answers are often wrong, but I decided instead to learn how to do some fancy (to me) compositing tricks to fake the display. For example the shot at 4:38 is manipulated- specifically the counter often adds in positions where it shouldn't, so I faked it. Good catch!

Der Krank 😂

did anybody get scared at around 3:51

What are the chances that mechanical calculators such as these were used to design atomic weapons? Of course, the fission bomb was used before the end of WW-2, but fusion? It would be exceedingly ironic if the hydrogen bomb was designed using Walther calculators.

The first Walther calculators appeared between the two World Wars, so it's possible that one of them made their way to Los Alamos. But there were comparable good American machines too, so I wouldn't say there's any reason to expect Walthers were used.
