I got it now, Olin.  I know where to start.  My goal was to get an overview of the page and then concentrate on the section you mentioned.  That is where I am going next.  

I'm ignoring others explanations for now until I untangle that section you suggested.  I figured I needed to know a bit of the input/output in order to next better understand the sub-circuit you mentioned.

I'll take your advice and not move any further past that.  You've been very kind to me to help me and it would be rude of me to try it any other way.  My apologies if it seemed I was going off in tangents.

I'm trying to help you, but you're not making it easy by jumping all over
the place.  You are getting way ahead of yourself.
