          Segement 0:SYSTEM INITIALIZATION & OVERLAY AREA
          ----------------------------------------------------
          This area is reserved for overlays to provide emulation for
          the Tandy Color Computer's, Apple II's, Commodore's, and
          TI's.  A seperate area will be provided for emulation of the
          Atari St, Amiga, and Macintosh systems.  CPM (MPM) and UNIX
          (XENIX) will not generally need this area.  However, systems
          not yet supported or mentioned, such as the TRS80 MODEL
          III/4 series (or the CBM/PET) will still have some kind of
          bridge or stepping stone to allow access to the features of
          this DOS.  So that if the demand or need arises, emulators
          will be developed.  Imagine a TRS80 MODEL 4 with color
          graphics!  Another application for this area would be an
          in-house developed, custom, proprietary system, such as for
          security purposes.
          
          The segments in this operating system are in sixteen 64K
          blocks for a total of 1M operating system memory.  The
          blocks can be expanded as necessary to provide room for
          growth and enhancements.  The main idea for this segment is
          to provide a cross-platform standard or compatability where
          needed or when demanded.  As mentioned earlier, one example
          would be a TRS80 MODEL 4 with color graphics, another would
          be better sound for the Tandy Color Computer, and still
          another would be more available free RAM for a VIC20.  All
          this WITHOUT losing ANY compatabillity at all with your
          already pre-existing software library.  Further examples
          will be provided in future segment discusssions.  Would a
          cross-platform cartridge adapter be necessary?
          
          Undoubtedly, there are probably almost as many non-IBM's out
          there (total) as there are IBM compatable systems.  Why let
          all that technology go to waste?
          
          It can be done.  Most of the systems mentioned had OS ROMs
          consisting of at least 32K max.  So, adapting these
          operating systems will be difficult at best, but NOT
          impossible.

          -
          This area provides the necessary means of converting from
          one proprietary or custom screen/keyboard code (ASCII) to
          another.  Such as from PETSCII (Commodore) to ATASCII
          (Atari).  As well as a means for BASIC number crunching or
          floating point arithmetic.  If possible, direct mainframe
          support will be provided, such as to and from EBCDIC.  This
          area also controls task swapping (Multitasking), shadow
          programs (TSR's), and memory management (such as psuedo-bank
          switching).  It also provides the means for growth and
          enhancements for the other segments.
