DOS & MINIX

[Pete Pardoe]

DOS was originally QDOS (Quick and Dirty Operating System) and was written
as a clone of CP/M for the 8088/86 processors.  There actually was a CP/M86
but Gary Kildall (Digital Research)  missed the call from IBM so they went
to Microsoft who originally licensed and then bought QDOS and released it as
PCDOS and MSDOS.  All Microsoft had at that point was an early version of
Microsoft Basic.

If anything DOS has it's roots in CP/M. Ahhh, those were the days!
Back in the days of using PIP, which probably had it's roots in
RSX or RSTS.

DOS was created in 1981 MINIX in 1987 so it is hardly possible for DOS to
have been created by
taking parts of MINIX. Do a search of the history of each on Google.

DOS was created by taking Minix and pulling out the parts that made a
single pc able to boot and run. Early versions of DOS even had the
Minix strings in the code. I saw that in the DOS 1 code using a hex
editor. :-)
