Rick -

I'll let you know what we find out here as I get the board up and running.  A question for you though, when you do an external 5V supply, do you simply tie the ground of the external supply to pin 6 and then the +5 to the wire that would have been on pin 5?  I'm thinking this makes sense, but before I blow a circuit (unlikely i know with only 5V on this machine...) I figured I would ask :).
