AppMod Connector diagram

I have a request for some simple devices to count people passing through a doorway and display the total on an LCD. ·
I have set up a PING))) Ultrasonic Sensor on a BASIC Stamp 1 Project Board
which· works fine, but I would like to add an LCD Terminal AppMod and only utilize 3 buttons leaving 1 pin free for the Ping Sensor.
This means I will have to remove one pin ( eg PIN 7) ·from the AppMod connector.
·
But I cant seem to find· a diagram showing the Configuration of the AppMod Connector. Where can I find that?

    You shouldn't have to remove a pin from the AppMod connector. That pin is only connected to the LCD which shouldn't matter if you're using 4-bit mode, a 10K pulldown which shouldn't affect the PING, and the 4th pushbutton which is open if you don't push it.

    The Board of Education schematic shows the AppMod connector pin configuration. Download it from the BOE webpage.

    Great - Thanks for the advice.

    I am happy if I don't have to remove a pin on the connector.

    Will try setting in the next few days
