        !             7:    For NCR Tower 32/4x0 and 32/6x0 running System V Release 3.
        !             8:    I don't have access to 200/700/800/850 machines, so I don't know if it
        !             9:    works on those as well.  It shouldn't be far from it however.
        !            10:    The hardware floating point support is completely untested, as I do
        !            11:    not have access to a machine with a 6888x FPU in it.
        !            12:    It does not work on the System V Release 2 based OS releases.  Making it
        !            13:    work will not be easy, due to the silly way in which stack expansion is
        !            14:    implemented in the OS.
