Because the Apple ]['s JoySticks were Analog Potentiometers, with Momentary Switches, other types of products could be connected and the Apple ][ could read their values.
The JoyStick Port has a Ground, ( Pin 8 ) and +5VDC, ( Pin 1 ), limited to 100mA.
Three Inputs, for Push Buttons, ( Pins 2, 3, & 4 ).
Four Inputs for Analog 0-150K Ohms, ( Pins 6, 10, 7 & 11 ).

I received some Disks with this SCI-COMP Box.
One of the Disks is for Experiments with "The Apple ][ Microcomputer Game Port".
I don't know if it was shipped with it originally, and I don't have the Printed Manual, but I am including the Disk for Historic Value.
