Blue Box
     
         The complete implementation of the {Mac OS}
        run-time environment on the more modern {Rhapsody} operating
        system.  {Blue Box} is not an {emulation} layer; at any given
        time it will be based on the same source code and ROM image as
        the current version of Mac OS and will thus incorporate future
        Mac OS improvements.
