Can anyone get me a good clear pix of the back circuitry? The pix provided just isn't quite clear enough - I may try to photo shop it to see what I find.
There is more to this then just what they show in the diagram.

No, there is NOT more to this than what I posted!
Pins 3 & 4 are counter reset
Pins 6 to 9 mom contact are count adjust down (SPST mom contact switch)
Pins 7 to 9 are count up (micro switch contacts) (NO and common)
There is NO relay on the back of the board or part of this circuit. There is no easy way to activate a buzzer or alarm from this circuit. The only way would be to layout another circuit board to connect to this one. Still not worth the time or effort. But I would absolutely love to see you try
Everything that I posted it 100% correct with nothing omitted or left out.
There is your picture
I'll explain it for you
It consists of one 5 volt regulator below the capacitor right side of board. It has 5 transistors, 2 caps , 4 diodes, 27 surface mount resistors, and one IC.
Unable to obtain number off IC probably house numbered device. Has no relay.
