Great!, I added a power jack, spliced into the 5 volt leads, heat shrank 
the loose ends that were in a connector, a little soldering, and it's up 
and running on my backup PC with a desktop 5VDC power supply. Will have 
to get a 5VDC switching wall wart with next order. Still would be nice 
to fix the problem, but this works. :) :)

Thanks again.
