Today we attempt to repair and refurbish a Monromatic CSA-8 electro-mechanical calculator from the 1950s-1960s. At the moment addition and subtraction don't update the accumulator among othet issues, I hope just from seized gears. #antique #calculator
I decided to start by fixing the shift mechanism, which stutters when shifting left. I'm hoping resolving that may also resolve some of the other issues. I was able to locate a service manual for a similar calculator which has some decent diagrams. #antique #calculator
@kyle Can you share a diagram - I'm curious about how these things are documented?
@penguin42 Here is the service manual I'm studying at the moment: https://archive.org/details/MonroeMSB440D
@kyle Thanks!
