+In 1975, Ken Thompson took a sabbatical and took a teaching job at Berkeley University, where he helped install Version 6 of /Unix/.
+The OS received quite the attention of students and faculty, resulting in the first version of /BSD Unix/ - /1BSD/.
+The lineage of BSD is extensive (not to mention their descendants are what I use) and will be a subject of the next part of our story.
+For now, remember that /BSD/ exists.
+The name will be all over the place, but proper history of /BSD/ lineage deserves deeper look.
+
+
+/Unixes/ we got to know here were research projects.
+People tried to understand what can be done with Computer using /Unix/ as the base.
+But no one was stopping other people from earning money.
+So they did.
+
+The first wave of commercial Unixes were mostly ports allowing to run /Unix/ on wide range of hardware.
+Remember, this was way before X86 desecrated the scene and computers there were vastly different computer architectures on the market.
+It was not small feat, and this is the hobby of a lot of folks in IT.
+/Doom/ is supposed to be ported to /everything that can compute/.
+The good old IBM PC got /386/IX/ (aka /PC/386/) in 1977.
+Amigas got their /Amiga Unix/ in 1990 developed by /Commodore-Amiga, Inc.//.
+HP's internal line of mainframes were given /HP-Unix/ in 1984.
+Most of those don't have any value now, but it's important thread in out story.
+
+*** Solaris
+
+However some of those forks have /huge/ value.
+Sun Microsystems (murdered by Oracle buyout) offered their own line of workstations.
+Their /Unixes/ were initially based on /BSD/ under the name of /SunOS/ - versions 1 to 4.1.4.
+Starting with version 5 however, the base OS was changed to /System V/ and the OS renamed to /Solaris/.
+Up to this day, this one of the most well remembered OSes.
+Mind you, it's still developed (in 2023), but people simply don't want to do anything in proximity to Oracle.
+
+*** Xenix
+
+Some /Unixes/ are remember for very different version.
+Xenix, released in 1970 was a fork for IBM/PC (among st others) released and developed by Microsoft.
+Yes, a timeline exists where Windows never became the standard, and instead a MS branded Unix rules the land.
+The firt version is said to be very close to /System 7/, but with time more and more changes were applied.
+It was quite the buzz in the buzz, even Intel sold a complete computers with Xenix preinstalled under the name System 86.
+Measured by number of machines on which it was installed, /Xenix/ was the most common /Unix/ variant by the mid-to-late 1980s[fn:wikixenix]
+Nothing of this mattered in the death march of Windows, and the last version was released in 1991.

+
+*** AT&T Strikes Back
+
+None of the systems developed outside of AT&T could use the name /Unix/, as the it was a trademark.
+The management of AT&T was paying attention and starting to get hungry.
+However, by 1980s, the most popular variant of non-commercial /Unix/ was /BSD[fn:wikiunixwars]/.
+
+The /Unix/ landscape was like nothing else.
+Despite companies sharing up to 90% of code, all the /Unixes/ were incompatible.
+Hardware and software vendors were unable to support all of them.
+The was no /Single Unix/, which made it the adoption much slower and painful.
+In 1981 Ma Bell (Mother Bell, a common colloquial name for Bell companies) helped a bit by combining all of Bell's /Unixes/ into a single one - /Unix System 3/.
+It's binaries were sub-licensed for 100USD.
+Nothing big enough to trigger legal actions, but /Bell Unix/ became a commercial product.
+
+This could not go like this forever.
+
+The change came from no one other, but the U.S. Department of Justice.
+The year is 1983 and the second antitrust case against AT&T is settled, causing the breakup of Bell System.
+This removed the decree from 1956 and AT&T was able to commercialize /Unix/.
+AT&T swiftly introduced the (aforementioned) /Unix System V/ (note the lack of /System IV/).
+You could now buy an AT&T /Unix/ for the low price of $43,000, though it allowed for commercial usage of the source code.
+Of course, add-ons (like networking) were sold separately.
+This product received it's own division within AT&T - /AT&T Information Systems/, later /Unix System Laboratories/ or /USL/[fn:ytchronicle].
+
+AT&T intended /System V/ to be the standard way to experience /Unix/, but others disagreed.
+The situation on the battlefield was complex, with different players putting their figures all over the place.
+We had two behemoths - AT&T with /System V/ and Berkeley University with /BSD/, now on version 4.2 plus a lot of smaller players.
+AT&T had all the money and name to crush anyone but did not support networking.
+BSD had a TCP/IP based networking and was popular among st universities.
+
+Vendor were choosing sides - IBM and HP went with /System V/ while others, like Sun choose /BSD/.
+On 27th of March, 1984 AT&T officially enters computer market with their own line of computers from desktops PCs to "super-microcomputers" powered by /Unix/[fn:ytchronicle].

+
+*** BSD on the verge
+
+The rules of the game also changed.
+All /Unixes/ shared code originating from Bell Labs, but AT&T was not happy with this.
+Therefore, while BSD still could be used for research purposes, any commercial usage would require first purchasing rights for /System V/ usage.
+The system came with license agreement allowing only for usage in academic institutions and purposes.
+
+By 1980s features of BSD were adopted back in /System V/.
+This, and the license made users and vendors flock towards AT&T, since they had to get a license anyway.
+Even curriculum was changed, since distributed source code of Unix (be it during lectures or in text books) were under AT&T control[fn:ytchronicle].
+This made /Lions Commentary on UNIX/ the most photocopied book in academic history.
+Owning Nth generation, barely readable copy gave significant bragging rights[fn:hiddenunix].
+
+*** Alliances - X/Open, AT&T&Sun, OSF, UI
+
+All of this made /Unix/ suffer.
+People were not writing software for it, since all flavors were incompatible.
+
+Seeing the situation, a number of companies joined forces to create a single standard .
+In 1984 the /Open Group for Unix Systems/ was formed by the likes of Bull, ICL, Siemes, Olivetti, and Nixdorf.
+The group was commonly known as /BISON/, from first names of their name.
+Later, the name was changed to /X/Open/.
+
+The group decided to base their standard on /System V/ because they "decided to run the risk of exploitation by AT&T rather than by IBM”[fn:michigan].
+The first version of the specification, X/Open Portability Guide Issue 1 was published in 1985 and “covered basic operating system interfaces”[fn:klara].
+
+The situation was, however, dire.
+In 1985 /MS-DOS/ had 5x the number of applications compared to /Unix/.
+This lead to the year 1986, and AT&T took a $1.2 billion loss, with half of that in computer industry.
+
+In 1987 AT&T and Sun enter an agreement.
+Sun, by that time, was the largest /Unix/ vendor with /Solaris/ based on /BSD 4.2/ and their own line of RISC-based microprocessors - SPARC.
+The official note stated that they are joining forces to "pursue co-development of a standard Unix operating system based on AT&T’s System V, Berkeley’s BSD 4.2, and the graphical capabilities of Sun’s Sun-OS"[fn:klara].
+
+The computer world was not happy with those giants creating their own front.
+The fear was that it could lead to a total domination of the market by AT&T OS running on Sun hardware.
+DEC engineer Armando Stettner, said: "When Sun and AT&T announced the alliance, we at Digital were concerned that AT&T was no longer the benign, benevolent progenitor of UNIX…Sun was everyone’s most aggressive competitor.
+We saw Sun’s systems were direct replacements for the VAX.
+Just think: the alliance combined our most aggressive and innovative competitor with the sole source of the system software — the balance shifted."[fn:klara], [fn:groklaw]
+
+This lead to the creation of third combined group - in 1988 representatives from Apollo, DEC, Gould Electronics, Hewlett-Packard, Honeywell-Bull, InfoCorp, MIPS, NCR, Silicon Graphics, UniSoft, and Unisys met in DEC's office in Palo Alto.
+Initially the group called themselves /Hamilton Group/ (from Hamilton Avenue, where DEC offices were located).
+Their goal was to get AT&T on board, but it failed.[fn:klara]
+As a reaction, they invited IBM who happily joined and in May of 1988 they official announced their existence under the name of /Open Software Foundation (OSF)/.[fn:ytchronicle]
+They decided not to base their standard on AT&T: "Unlike X/Open, OSF planned to produce an operating system that it would license to its members, rather than function only as an advisory body."[fn:klara]
+
+This had the historical effect of putting rivals, DEC and IBM on the same side.
+DEC co-founder, Ken Olsen never before shared a stage with any IBM executive before.
+Even Ken Thomson while traveling in Australia commented on this to Dennis Ritchie: "Just think, IBM and DEC in one room. We did it!"[fn:ytchronicle].
+Sun's CEO, Scott McNealy was not as pleased, as he called the OSF the "Oppose Sun Forever".
+The heat lead to AT&T and Sun creating /Unix International/, whose goal was to advice AT&T on /System V/ and promote its development.
+The voting rights were based on, of course, financial contributions[fn:klara].
+
+OSF faced internal problems due to consisting parties often competing on mainframe market.
+This left OSI and UI as the dominant powers in the straggle, and in total they ended with over two hundred members.
+Both also developed and released their own Unixes.
+In November of 1989 AT&T releases a commercial version of /System V Release 5/, and in 1990 the OSF released /OSF/1/ based on IBM's AIX and Carnegie Mellon’s MACH operating systems[fn:klara]
+
+*** Enemy mine
+
+The battle continued into 1990s, and there was no sign of a clear winner.
+First, the economy turned to the worst with the early 1990s recession in the US.
+Most players of the Unix Wars, as we call them now, started seeing decrease in profit - sometimes loses.
+Second, 1993 saw the release of /Windows NT/, which was aimed directly at the market /Unix/ was fighting for.
+Having a single, widely supported OS allowed Microsoft to quickly gain huge market share.
+
+/Unix/ fought with more standardization attempts.
+
+Firstly, in 1988 the IEEE 1003 was released, /Portable Operating System Interface/, aka /POSIX/.
+
+The second was known as /Common Open Software Environment/, the /COSE/.
+It was one more attempt to create an open, unified, standardized /Unix/.
+This time, however, it was not an fight between /Unix/ vendors.
+This was the first time they had to unite against a common enemy.
+Initially the group consisted of The Santa Cruz Operations, Unix System Laboratories, Univel, Sun, HP, and IBM
+They tasked themselves not with creating of a single unified OS, but rather with survey and document what already was there.
+The result of their work is /Spec 1170/, now known as /Single Unix Specification/.[fn:klara], [fn:wikicose]
+
+
+This lead to the last attempt.
+In 1996 OSF and X/Open merged and became /The Open Group/ which exists till today.
+It was however too late for /Unix/ to regain it's dominance.
+The value was lost, the /Unix/ wars saw the raise of Microsoft and a new player - GNU/Linux.
