Analog computers had their heyday from about 1940 to the late 1960s but their important legacy lives on. According to a Wikipedia definition, “An analog computer is a form of computer that uses the continuously changeable aspects of physical phenomena such as electrical, mechanical, or hydraulic quantities to model the problem being solved. In contrast, digital computers represent varying quantities symbolically, as their numerical values change.” Most were designed for very specific applications, like heavy-duty math or flight component simulation. Here’s a look at just a few -- there were many, many more examples – of some of the cooler analog computers.
