Old Wacom tablet and OS X
 

A friend of mine is giving me her old Wacom Artpad II (with a serial connection). I know I can buy a serial to USB connector so I can plug it into my iMac but I can't find a driver on Wacom's site for OS X (they just list 9).

Does anyone here know if I can get this tablet working in X? I'd really love to finally get a tablet and free is always better than $200-$300.
