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. This file is included in tower-as.h.
