MOTM

Hi Dave,

Aren't there electrolytic caps where the power comes on to the PCB? If so, 
you should be able to determine which is +10V, and which is -10V by checking 
the orientation of the caps.

If you don't mind, I'd like to ask you to do a few measurements on your 
ribbon:
1) What is the resistance of the resistive material across the length of the 
ribbon?
2) Is there a spring mechanism (causing the touch strip to retract) of any 
kind on the touch strip of the ribbon?
3) What is the distance between the two strips (conductive and resistive) 
when no touch is applied?
4) On a picture I've seen of the Moog ribbon it appears to have a large 
Cinch/Jones plug in the middle of the cable which terminates to: the 6 pin 
Cinch/Jones plug, a two pin Cinch/Jones plug (for the S-trig), and two 1/4" 
phone jacks -- one is clearly the ribbon CV out; what's the other one for?
5) Any idea what the resistive material is?

I hope you can get it working with your MOTM.
