ATTENTION:  CartMaster has undergone several hardware enhancements
            starting with serial number 2000. Owners of earlier
            serial numbers should contact customer service between
            9:30 am and 4:30 pm EST at 516-473-2507.

Several owners requested software that could be used to switch ports
without any user input. This software is now included.
 
     The files PORT1A.PRG, PORT2A.PRG, PORT3A.PRG, and PORT4A.PRG,
will select the appropiate port for those units being used in the
default memory mapping mode "A".

     The files PORT1B.PRG, PORT2B.PRG, PORT3B.PRG, and PORT4B.PRG,
will select the appropiate port on those units being used in the
alternate memory mapping mode "B".
