Finally getting around to fixing this up.
I purchased this in 2013 ??? I think.
Sorry Warren.

This is the second panel from the second box.



    Panel 2 of Box 2:
  • 1 Dual Positive Slew
  • 1 Dual Negative Slew
  • 2 Envelope Generators
  • 1 Triple Bi-directional Router
  • 1 Triple Comparator
  • 1 Schmitt Trigger 
 ------------------------------------------------------------------------------------------
Schmitt Trigger & Triple Comparator


The Blue wire seems to be ground.
The Green is I think +12V

Bi directional router

Links:

 Double check the wiring by looking at what the pads are labeled.
X=+VE
W=0V
Z=-VE

In this case, 
The blue wire at the bottom is -12V
Red is +12V
There is no 0V/GND connection to this module.
-------------------------------------------------------------------------------------
Envelope Generator. We have 2 of these

The boards are I believe 1st generation ... from 1973


Links:

 Double check the wiring by looking at what the pads are labeled.
X=+VE
W=0V
Z=-VE

Blue (near the pots is marked W on the PCB) is ground.
Red (X) = +12V
Green (Y on PCB) = ??? My guess is its +6v.


Below are some pics from an extra Envelope Generator PCB. Its marked R7 so 
is possibly also 1st generation, 1973.
This is not part of the Warren Burt pile but it might help me work things out.
Lovely dark blue colour too.
