    It was its own universe, Jim.  The links and questionable parentage
of the original version of DOS are tied directly to CP/M, which was the
first O/S for personal computers that any significant number of
businesses embraced.  And, Windows came out of the DOS world, and now
dominates as few products have dominated before.  (Note: I am NOT
claiming this is a GOOD thing.)

    From what I can tell, TRSDOS was not a rip-off of anyone's software,
and nobody bothered to rip it off, so it's pretty much out of the world
of O/S scandal.  It actually was pretty decent, and had a few ideas of
merit that didn't make it into the mainstream world for a while.  It was
just totally tied to Radio Shack computing, and suffered a mortal wound
when IBM came out with their PC.  No fault of its own.
