| 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. | |
