To Ken Stone, Steve Ridley and all who sent me information on this, I thank
you profusely, this all started because I had a rather crappy scan of a
drawing that violates some rules of schematic drawing and one of the diode
connections was unclear.  Now I have several extremely clear diagrams which
will be easy to both follow for building and finally understand exactly what
this circuit is doing.

Once again, this list proves it's value and the generosity of it's members.
