Yup, MS DOS v1.n was a rewrite of CP/M86 (Control Program /
Microcomputer for the 8086 processor). DOS v2.n was an entirely new
kernel, with a command set largely stolen from Digital Equipment Corp.'s
VMS (currently owned by Hewlett-Packard), and a file structure modeled
after U**x.
MD DOS v2 was a good move, making the command set much less cryptic than
CP/M, and a file structure that would easily translate to the standard
of what would in 10 years become "the Internet".
Apple's OS X wasn't exactly a "new" write by apple. They built a GUI
based OS on a new kernel developed by NeXT; it was pretty much the same
U**x kernel used by freeBSD.

Personally, I think it will be a sad day if MickeySoft ever does
this. One of the main reasons I use Windoze over other OS products is
the fine control I get from the DOS command line. Apple has nothing
that is truly comparable. A cool GUI is not sufficient for my needs.
It might be noted, too, that MS had continued to add features and
refinements to the DOS command set, even through the Win2000, Win-XP
rewrites. Dunno about Vista, still no experience with it.

named Seattle Computer which was who Microsoft bought it from. I have heard
that it was a re-write of Kildal's C/PM, but I don't know that for sure. I
do remember that very similar commands had slightly different syntax in DOS
vs. C/PM. But then I have always been in over my head with computers, which
is why I had the Sol 20 kit assembled by the Retail Computer Store way back
when.

This is starting to get pretty far of topic, but the command line
control available in MacOS X is far superior to the DOS command line
prompt in Windows. I've used both extensively for years and DOS is a
toy compared to any of the unix shells in OS X (sh, csh, ksh, tcsh,
bash, zsh, etc.).
