     Some may; don't know. Apple II, C64/128, and PC all use buttons which are
normally open.

     An important difference in button switches on Apple II vs. other popular
sticks (like PC and C64) is the logic value of a pressed button. On the Apple II,
pressing a button = "1" (the line is connected to +5).  On PC and C64, pressing a
button = "0" (the line is connected to GND).
