Even back in the mid to late nineties, you still had a bunch of different Unix OS's and their associated hardware: * AIX / POWER * Solaris / Sparc * Irix / MIPS * HP-UX / PA-RISC And probably some I'm forgetting.

DEC Alpha was another big one. Digital Unix (AKA: Tru64, OSF/1) / Alpha

  That brings back memories. The first time I ever heard of Digital Unix was in college looking at netcraft.com's web server ranking, where it showed that www.amazon.com was running on OSF/1. I figured if Amazon was using it, it must be worth looking into. Found an Alphastation in an IT storage room and had some fun playing around with it. Good memories.

    Yes, Alpha was incredible for the time. Sparc was a dog in comparison. Software wise, Solaris felt more standard though. I remember having to tweak open source stuff to compile on Digital Unix. Solaris almost always just worked.

We're talking about 1982, not 'mid to late nineties'. None of those chips even existed. Silicon Graphics Unix was running on 680x0 based series 1000 machines (and wasn't called IRIX yet). HP/UX was running on 680x0 based HP9000 series. AIX was a couple of years away and would first run on the RT/PC development of the 801 project, not on POWER. In 1982-ish IBM did have a Unix machine tho...the 9000 series, which was a 68000 running Xenix. DEC hadn't started PRISM, much less ALPHA then...it's Unix was Ultrix on VAX and PDP-11.

  Yes, I read what was written. My point was that there were still a lot of companies doing Unix systems years later.

    No, there weren't. There were the few you mentioned, and a dozen or two others. I worked with most of them. The point was that in the early 80s, there were a far larger number. The only real similarity was that like the '80s were the days of mc68k and Unisoft, the majority of the 90s Unix vendors were x86 and System V, all from the same code base.
