IBM PC XENIX 1.0
|

---
|
||
|
||
From [OS/2 Museum](http://www.os2museum.com/wp/ibm-pc-xenix/):
|
||
|
||
> The IBM PC XENIX was based on AT&T’s UNIX System III (rather than the newer System V) with a number of BSD
|
||
enhancements. The latter included vi, C shell, and termcap/curses. Microsoft also implemented several enhancements,
|
||
such as the ability to read and write DOS file systems.
|
||
|
||
> Much like other Xenix variants before and after, IBM PC XENIX was optionally shipped with Text Formatting System
|
||
(TFS) and Software Development System (SDS) packages. The TFS was based on the classic nroff/troff formatters and
|
||
associated utilities. The SDS included a compiler, assembler, debugger, and assorted development tools like SCCS and
|
||
make.
|
||
|
||
> One of the Microsoft-specific enhancements was the ability to cross-compile to DOS using the SDS. The XENIX to DOS
|
||
cross-development capability was likely frequently used internally at Microsoft in the mid-1980s.
|
||
|
||
> The IBM PC XENIX came with rudimentary networking capabilities, namely uucp and micnet, though little is known about
|
||
their specifications.
