C64 and Analog Computers

[Ami_GFX]

The most common analog computers use op amp circuitry: Adders, subtracters, multipliers, integrators, differentiators, logarythmic and expontial amplifiers among others. They are very similar to analog modular synthesizers in their ciruitry. Equations are programed by patching modules together. They are more like real world mathematical modeling systems than computers in the digital sense.

I've gotten to play with a few modular synthsizers in my time and I've seen pictures of analog computers that looked like they would be interesting audio processors among other things they could do.

Here's a couple of examples of analog computers:

And here are pictures of Serge and Moog modular synthesizers for comparison:
