Scanimate Tour: The CPU

When I first got acquainted with the Scanimate in 1980, I had worked with microprocessors, building my own single board computer based on the RCA 1802... but that's another story. The point was that it took me a while to get used to calling a bunch of analog ramp generators, summing amps, multipliers, and phase-lock oscillators a CPU! But analog computers had been around a long time. The beauty of them is that you can have literally thousands of variables, each connected to a knob, and turning any or all of them produces an instantaneous (well, almost!) solution at the output(s). For animation, this was great, because you could show a client the element you were working on right then in finished form. He could suggest changes to the movement, appearance, whatever he wanted, and you could turn a few knobs, move a few wires, and there it was. Want it a little slower? Turn a knob. Want it exactly 10% slower? Forget it! Want exactly the same thing we did yesterday? You can forget that too! There is no such thing as duplicating a job on a scanimate. The phases of the moon, the earth's rotation, the cosmic karma of the gods of Analog all contributed to each masterpiece being necessarily unique! (That's the best spin on it I've ever read, if I do say so myself!)
