   Uh, not easily anyway. The 1350 is a "joymouse" - moving it in a direction 
sends the same signal back to the computer as leaning joystick in the same 
direction. The lightpen/fire line is connected to one of the buttons (I think 
the other is connected to one of the paddle lines).

   This would require internal mechanical modification - probably more 
expensive than simply going out & buying a 1351 proportional mouse.
