Don't need no stinkin' CS-80 video...
...I can just walk across the room!
Now, about analog computers...first of all, they're a massive royal pain. Remember, this is complex tech from, at the very latest, the late 1960s (Comdyna's models notwithstanding)...with the hazards inherent in finding documentation from that period being all over the place with them. F'rinstance, I have THREE Systron-Donner 3300s. But none of them are properly functional. And this is because Systron-Donner dumpstered their old equipment docs back in the late 1980s, making locating service docs a task that's beyond head-explodingly difficult! I've been on that trail since the late 1990s, still without success.
But item #2 is...well, if you think the CV restrictions on the AE System are a bit to wrap your head around, try wrapping your head around +/- 100V outputs. There are a few transistorized analog computers that work in the +/- 10V range, but the vast majority of these things (such as my Systron-Donners) swing from +100 to -100 volts. Now, it would be NICE to modify one of the Systron-Donner mainframes so that it has attenuated outputs...a 20:1 voltage reduction would drop things right into that 5V ballpark (although that would still be bipolar 5V...would need CV foldaround to sort that), but you need the schematics to see how that would work best.
Third...they ain't user-friendly! For one thing, each of these Systron-Donners is a big chunk of steel about the size of yr.typ mixing desk...but it's got "big iron" in it and it's built to scientific specs, so despite the handle on the top, you could hardly consider one of these monsters to be "portable". And these are SMALL analog computers...the BIG ones can take up a deskspace the size of a small car! And then once you deal with all of that...you still need to know how to program them, and that's not exactly like programming a typical modular synth.
But then...when you see them in action in that Hainbach clip, you understand why they're useful. SOMEday I hope to have one functioning here...
