   I managed to
pick up a COMDYNA GP-6 analog computer a couple days ago out
 at University Salvage.  I initially bought it for its nixie tubes, not
 knowing what it was, and then was a bit dissatisfied with the fact that
 they were not in great shape.
 After taking a few seconds to look at it and try to determine what is was
 with all the banana jacks on the front, I thought "Hmm, it adds and
 multiplies... google says 'Analog computer'... Wahooo!!" 
 More info about the one I have - looks to be an early model - with nixie
 tubes intead of the modern LED voltmeter. 
 
I have two of these I would consider selling to fellow list-members (or
trade for a Processor Technology SOL  :)   :)
Mine have the more modern displays, not nixies.  Nice, beautifully built
analog computers.  Contact me off-list.
