I'm sure all of us who are interested have already done so.
As far as the "instruction" goes here is an example:

>As integrators, output voltages equal the inverted
>integral of the sum of the input voltages (plus/minus the initial condition)
>where the integration rate is the reciprocal of the R*C
>time constant.

I haven't got a *clue* what that is all about. Maybe you think that the
GP10S is unsuitable for those who haven't had a background in the sciences.

Therefore Dan is presumably in a better position to sell us the concept of
analog computing than Comdyna themselves. The analog computing examples on
Dan Slater's website seem (at least to me) to be primarily 'chaos' based.
There has been some mention of sequencing, state variable filters etc..
all I'm asking is for some more info on that side of the computer.

I believe we've already been quoted $950.
