The TOS operating system is not based on CPM68k. It is instead derived
from MS-DOS. The reason CPM68k was rumored as a basis for TOS is that
the C-compiler that comes with the development kit was ported from
a CPM68k environment so the runtime library has some remnants
of CPM68k conventions. By the way the ST does have multitasking of
a sort. Basically the processes have to call a get event routine that
then calls the next routine on the ready list. The basic idea is
to have one main application program and the desk accessories
share time so that one can have printer spoolers, etc.
running in the background.
