            One  of the most exciting things to happen for the Atari
            8-bits  in the last month or so of 1989 is the advent of
            the  Stereo  modification  by Chuck Steinman, nick named
            the "Gumby" mod.

            In  a  nut  shell, this modification adds a second POKEY
            chip  to  your  computer  and  allows  you  to  have two
            channels  of  4  voices  each. This leads to TRUE stereo
            sound  output  from  the  computer, something that Atari
            should have done years ago.


            These   five   Action!   routines   will  allow  Action!
            programmers to access the new voices in the same fashion
            as the original voices.


            Included here are four new routines:

                                     SndLo
                                     SndHi
                                     SRLo
                                     SRHi
                                     Gumby
