I have had a little more time to examine the board. On the oper pins, left has 3.3 v, center goes to pin 14 and right is ground. I have retouched all of the solder points. I examined the working board with this one and all parts look right. Diag hex works fine. When I power the unit, LEDs flash, but nothing happens when I change the jumper from oper to prog. Odd.
