     Alright, I too would like to see what Mike is talking about.  I am as
green as they come, and here to learn.  What really worries me, is I
don't understand what Mike is saying.  I hope that maybe he could put
me on the path.  I am really wanting to understand the non-digital
circuity.  I am sadly lacking in understanding.  I would love to see
a more elegant way of doing it.  I've got the time.  I seonded it.
