   Well, here's a quick program in Basic to do that:

10 X=PDL(0): FOR I=1 TO 10: NEXT: Y=PDL(1)
20 PRINT X " " Y " " PEEK(49249) , PEEK (49250)
30 GOTO 10

   That checks the X/Y positioning of them, as well as the buttons.
The first number per line is the horizontal position, th second the
vertical. 0,0 should be top-left, and 255,255 the bottom
right. Properly centered joysticks should be about 127 (+/- 5 is fine
for almost all programs) The third and fourth numbers are the two
buttons (also your open-apple and option/closed apple keys). The
button values will be <128 if not pressed, and >=128 if pressed.

   The little loop with I in line 10 should be left in-- you should
have a small pause before reading each axis of the joystick. (The
print takes long enough that it's the pause)
