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