You could set up "partitions", which mean reserve fixed amounts of RAM for different applications.
It ran on the (8 MB I think) external hard drive for the TRS-80 model 16.
An advantage compared with Xenix is that it was smaller (used less of the hard drive).
Also it had just a single directory, but had a form of hierarchy in that you could use any number of '.'s as separators: like usr.bin.ls. The total name could be long. I think OS-360 worked something like this.
I think the last line of the screen was always the command line, and the other lines were for command (or cobol menu screen) output and worked like a pager.
Thanks! That last link is helpful! It's actually quite an interesting and capable OS. Has file & software protection mechanisms. I recall UNIX having about no reliability at the time. Also, coding, compiling, and directly running without linking the apps is closer to a LISP machine than regular OS of the time.
Might give it at least a brief Wikipedia article with these links.
I remember a little about it:

You could definitely hook up serial terminals.

It's the same as "COS990", but for 68K.
