; Atari 8-bit mouse routines -- 05/07/2000 Freddy Offenga
; Some changes by Christian Groessler, Ullrich von Bassewitz
;
; The following devices are supported:
; - Atari trak-ball
; - ST mouse
; - Amiga mouse
;
; Mouse checks are done in the timer 1 IRQ and the mouse arrow is
; drawn in player 0 during the vertical blank
