In 1992 VAX/VMS from Digital Equipment Corporation was beginning to feel the hurt from various Unix systems that were becoming popular. In 1993, I worked at a US Army contract that still had MS-DOS and we had to do some creative accounting things to get them some systems that could run Windows 3.11.

There were still a bunch of proprietary systems like Apollo that had were used in a lot of engineering places. Unix came in two flavors, BSD System V and Berkeley. Linux hadn't happened yet but open source had made its presence known by all the utilities that ran under Unix with familiar names prefixed by a g- like gawk, gcc, gtar, etc. Before the GNU project, each vendor had their own C compiler that came with their version of Unix. The GNU utilities slowly made those obsolete as gcc became the standard C compiler.
