Recalling The Days Of Analog Computers
Analog computers were actually designed real-time by the user, with a different design every time a new set of equations was run. That was because they were a series of operational amplifiers which had feedback loops that determined their mathematical output function and these were hooked together in a manner for simulation of the solution of the equations for a specific input. For a differential equation (not really available on the mainframe), you could integrate and differentiate depending on where you inserted the capacitor. It was very cool and it was very techie for the times.
