First, thanks everybody for the answers on the Disk II pinout question.
I ended up buying the cable for the //c (also works on GS) from JDR in
San Jose for $10, in case anybody else is looking for one.
 
Now on to the next question.  My GS seems to have an interesting quirk.  All
old (DOS 3.3 and Prodos 8) games work fine with the joystick.  However, if I
boot up a Prodos 16 game (or run it from the Finder), the joystick isn't 
recognized about 2/3 of the time.  When it isn't recognized, I simply reboot
to a BASIC.SYS disk and run a simple program which uses PDL(0) and PDL(1) (both
needed), and then I reboot the Prodos 16 game, and everything works OK.  
The big question - why???  Is this a quirk or is my GS dying.  It might be 
worth noting that this problem first started occurring when I once booted up
with both a Koala Pad (in the 16-pin connector) and the joystick (9-pin)
connected, and I removed the Koala Pad (very carefully) when the power was on.
