Because my "hard disks" are FreHD, MISE and M3SE  I have multiple
operating systems.  I plan to work with CP/M, TRSDOS, LDOS, LS-DOS,
DosPlus and NEWDOS80.  They were all the ones I worked with back
when the TRS-80 was still new and I actually still have copies of
disks and documentation for most of it.  CP/M and DosPlus were my
favorites.
