The standard joysticks with Autofire (for example QuickShot II) don't work with Enterprise when using simple wired joystick interface (just the AutoFire not works).
I thought there is the question: how possible to work with Enterprise.
a) modify the joystick, replace the cable with direct Enterprise cable, and adding transistor to the Autofire circuit.
b) build a active joystick adapter (originaly developed by BoxSoft), which can work with any joysticks
