Agreed.  But the original thread had to do with analog computation, 
no?  Since the main use of analog computers is to solve diff eqns, it's 
hard to see why you would want one if you didn't have that level of 
math.  If you just patch up some combination of computational modules you 
will almost certainly get nothing -- the system will either decay to zero 
or take off to the rails.

But anyway, my previous comments were directed to the person who said I was 
wrong about offset causing drift, not to what you were saying.
