Concurrent DOS was one of many.  I remember using a product called
Thoroughbread(I might have the spelling wrong) that offered a multi-user OS for
IBM compatible systems back in ... 1985 (I think).

When CP/M was made, it was set up like a computer/terminal configuration.  You
had the computer here, running programs.  It sent data to a separate subsystem
(usually separate hardware in the box) that actually displayed the data on
something.  Same for taking input.

A set up like that made a multi-user MS-DOS really easy to do.

But by the time that came out, too many programmers were used to owning the
whole computer with their software.  So that separation wasn't possible with
the current applications.

So Concurrent DOS was nice, it also didn't work with the apps that people
wanted to run.
