Actually all analog computers are _not_ the

For example: Resistive Sheet computers are very

You typically use resistive sheets with op amps no? I
just look at resistive sheets as an accessory of a
analog computer like the EC-1, just like caps,
discrete resistors and wires are accessories.
But can I get a bunch of resistors and a power supply
and call it an analog computer, sure I can, I guess I
should of said "typical commercially available widely
used analog computers"
Resistive sheet computers were sophisticated commercial devices, not a "bunch
of resistors" I have seen a couple of them so I doubt that they are all that
obscure...
