Hello, would anyone know anything about analog computers such as the Comdyna gp-6, and specifically the model 771 Transfer function simulator? I just have a couple of quick questions. thanks,

 

I have experience with analog computers from a bygone era (ca. 1968). Today I use LTspice to simulate transfer functions.

I'm not familiar with that product, but page 17-18 of the manual indicate how the transfer functions are implemented. That's certainly old school, ( as a co-op student in 1977, I did analog programming at NASA), as it's easier to experiment in software. See the following link for the manual, (found with Google search):

Here is one from Qspice

 

Thank you, this is very interesting.
Off topic, but I've in my earlier years I've had many opportunities to visit Elbonia
on my stop-overs.
interesting people, wonderful cuisine.

Top notch education system to boot!
