      I'd bet that "floating" Reset is "top of this list"

      Good for you - devil in the details - you'll learn as you experiment - gain experience.  The JTAG probe provided the active or pull-up level to satisfy Reset - once the probe was removed the floating reset wreaked havoc.

      Neat Green "Verified Answer" tick would be appreciated.  (help me "close" upon dreaded awneil...)
