I built this, added some knobs to twiddle the
parameters,
and hooked it up to a 10" X-Y display and am very happy :-).
It'd look
nice on a Tek 555 'scope sat on top of the Elliott 803 at the museum :-)
I highly recommend it!
Historically a lot of chaos research even in the 80's was in fact done
with analog computers. It certainly is more fun to move wires around
a plugboard and tweak knobs and see the result on the scope, as compared
with editing computer code or point-and-drool with a mouse and then
running it and then seeing the picture!
I built a two player (team) football game in the early 70's
out of analog computers (integrators, adders, etc.). It was
wicked cool sprawled out on a 4'x8' sheet of plywood. One
of those "guaranteed 'A'" projects that teachers drool over...
