Intelligence Before Measurement

Sure, IBM has always been associated with computing, but this restoration shows they were in it way before electronic computers became a thing. This calculating cheese cutter uses a complex mechanical mechanism that translates a few known numbers into a angle to turn a wheel of cheese a perfect amount of degrees before cutting it. Based on the angular movement dictated by the levers, you'd get a piece of cheese that weighs the proper amount, and it would tell you the price for that weight too.

Other than that, it is a very insightful video, which shows many techniques used in restoration.
