Highlights from an extensive collection of early minicomputers, mainframes, and instrumentation remind us just how amazing smart phones are.
This solid-state analog computer could solve complex equations but was limited to about three digits of precision. It would have used a ±10 V voltage range to cover the range of numbers desired. The sections, which correspond roughly to the different colors on the patch panel, include op amps that can perform addition, subtraction, integration, and differentiation. By wiring a number of those in a row using the ports in the colored areas, users could perform simulations, solve systems of equations, run interpolations, etc. The array of black dials at the bottom could be used to set constants.
