   How exactly does a person read standard Atari paddles from assembly?  The
following fragment would seem to be correct, but Intuition doesn't like the
"move.w  d0,$dff034" - it thinks it has RMB events.

         move.l   _GfxBase,a6          ; C has this variable
         jsr      WaitTOF(a6)
         moveq.l  #1,d0
         move.w   d0,$dff034           ; start paddle timing
         jsr      WaitTOF(a6)          ; data ready next vblank
         move.w   $dff012,_Pot0Dat
         move.w   $dff014,_Pot1Dat
