Is the ribbon cable from programmer to 840Z ZIF plugged into the header on the ZIF

Of Course..... how could I miss that. To much staring at computer screens, I am going blind. Thanks again for the quick and perfect answer. I do appreciate the advice and hopefully will one day build up enough knowledge to be able add some value to this excellent forum.
