- It may be arguable whether Tim Patterson is a genius or not, but it's
- true that he wrote the original version. Though he originally called it
- QDOS, Seattle Computer Products (his employer at the time) called it
- 86-DOS.

- Pardon my pointing it out, but this is roughly like saying "A 747 is
- just a paper airplane any schoolkid could fold up with some
- optimizations and meaningless features added."
-
- Consider that 86-DOS' file system used extents like CP/M's instead of
- FAT. (It may be fashionable to slam FAT now, but it was a drastic
- improvement over extents.) 86-DOS didn't support any kind of i/o
- redirection, or ability to treat devices as files. It had no
- subdirectories. It supported only .com files, with no relocation
- ability. It had no memory management or support for TSRs. It had no
- ability to load device drivers. If you want an idea of how much MS has
- changed DOS, pull out a copy of MS-DOS 1.0, and see how many of your
- current programs will run on it. Then keep in mind that even DOS 1.0
- was already changed considerably compared to 86-DOS.
-
- The reality of the situation is almost entirely the opposite of your
- statement: as of DOS 2.0, virtually all of MS-DOS had been completely
- rewritten from the ground up, and essentially all that was left of
- 86-DOS was a set of compatibility functions. The majority of these are
- virtually never used except by ancient programs converted directly from
- CP/M.
-
- Finally, keep in mind that MS-DOS is _far_ from the only system MS has
- written over the years: MS is also largely or completely responsible for
- OS/2, Windows NT and Xenix.

-
- An excellent idea. Making some attempt at educating yourself on the
- subject matter at hand prior to posting would be a good start at that.
