One way that I have found to test programs whos nature is untrusted is the
following:
	On my cp/m 80 system, I run a copy of a special version of my CP/M 3
that knows only about the floppy disks. The worst that can happen is it trashes
the floppies and I have to diskdup them again.

	On my MS-DOS XT, My hard disk is formatted for MS-DOS 3.0.  When I
boot of off a MS-DOS 2.1 floppy it doesn't reconize my harddisk and won't
work with it.  But I also run a vdisk from 3.0 that sets up C: to be a 
340k floppy and my autoexec.bat copies all of my standard tools to the C:vdisk.
	I can then open the A: drive and now there are no real disks left
available on this "virtual system".
