The Facit mechanical calculator
Calculating machine. I used this to do statistical analyses in the late 1960s at Ohio State University. There was a room full of them. I would enter my numbers, start it working, then I could go grab lunch while it calculated sums of squares. It was noisy and so heavy that it shook the desk back and forth as it calculated.
