news DOS simply loads TSRs, it doesn't 'manage' them.

Then what gives each program time on the CPU?

DOS is single-tasking. In DOS, there is only ever one program at a time
executing. The currently executing program "owns" the machine. There
is
no "executive", there is no time slicing of CPU time.

I fell in love with DesqViewX. It was among the first for the early
x86 architectures to slice things up well.

Yeah, I ran DesqView and DV 386 (not X) for years. I actually got X but
never used it.


I never used the task switcher predecessors. It still seemed a lot
like single tasking to me.

I used DesqViewX. It was the first OS that allowed remote processes. I
could run an app on another box, and get the screen and keyboard I/O on
my local workstation. So I could run things on dormant boxes anytime I
wanted a process to complete sooner than it would on my machine.
