      ========== REPLACE FIRST PARAGRAPH ================

      A floating point co-processor is no longer supported. Instead,
    some of the instructions and data types previously supported
    by the MC68881/MC68882 co-processor are handled by a floating
    point unit built into the MC68040 processor itself. The instructions
    and data types not supported by the floating point unit will
    generate exceptions where they will be emulated in software.
    The built in floating point unit together with the emulation
    package allow code running on pre-MC68040 series workstations to
    run on an MC68040 workstation without change.




     ====== NEXT TO LAST PARAGRAPH ===============


       Because some of the floating point instructions and data types
     are supported directly on the processor, many programs that
     contain floating point instructions will run correctly without
     the emulation package FP40 installed in your system. If you
     should encounter the message

     error -13: illegal cpu instruction

     or

     error -31: undocumented error

     while running a program containing floating point instructions
     on your MC68040 workstation you may have encountered an emulated
     instruction or data type. You should install the FP40 package
     in your system as described above and try the program again.
     When in doubt, the FP40 package should always be installed when
     using any floating point instructions.
