[kl-bogel] Analog calculator (3 photos)

Analog calculator. 1967. You can add, subtract possible. Operations are a special aluminum rod. This calculator was in my usual, but I did not use them, because in the analog age like anything digital.



The process of composition is as follows. The first number is dialed by moving the sector from the top down the right numbers. Assume that the number 57. Add the number 5: around the number 5 red dots, then have to move up to the end. At the top of the rod moves to the next level, and there is shift it down until it stops. Turned 62.



Subtraction is similar, only the lower part.
