Let me help point out how misguided most of this is and some of the really really BIG WHOOPPERS:
I am not sure what phamplet you read this out of.. most likely one you got at a recent trip to Microsoft re-education camp.. but this a really bad falsehood..
BSD UNIX is the MOST WIDELY used UNIX THEN AND NOW and probably forever... >>
Er. The only BSD that's a UNIX is BSDi (if that). The others aren't. UNIX is a trademark, it has very specific requirements. Those requirements are set by the OpenGroup (
http://www.opengroup.org/), the trademark licensing is also performed by that group.
That hasn't always been the case; the trademark has been sold from organization to organization, but that's what's currently the case. The most widely used UNIX (as in, OS that can actually call itself UNIX) is probably Solaris.
<<
XENIX might have been the most widely used UNIX on INTEL systems back then, but of couse there was ONLY the 386 chip and back then the total INTEL system market was just a drop in the bucket of today, >>
No; an awful lot of such machines were sold. The numbers were certainly dwarfed by today's numbers, but were still high. Particularly as the mainframe-type machines that also ran UNIX worked so differently (because they were so much more powerful, comparitively few of them were sold).
<<
so that like saying that at best a total strech of the truth past any reality, and at worst a bold faced lie. XENIX was a derivitive of SYS V - Release 3 Unix BTW, which came LONG after BSD was well established all over the world. >>
But not on many _machines_.
<<
AGAIN... another example of a bold faced lie by a greatly mistaken Microsoft driod... I am sure you are much too inexperienced to know this, but SQL Server was "BORN" on UNIX, and was called SYBASE for many years... Microsoft purchased a license of the source code for SYBASE version 5 a few years ago, ported it from UNIX to Windows and called it SQL Server. >>
No, that's not entirely true. They licensed Sybase's product, yes. But the first version of MS SQL Server was for XENIX. Hence, SQL Server was born on XENIX.
SQL Server 6.5 was, IIRC, the last version to contain the Sybase copyright when it started, so I assume that all the Sybase code has been removed in version 7 and 8 (2000).
<<
This is a yet another example of what Microsoft calls "innovation" and we all call boring stealing of others work to pretend its their own invention, and sheep like you actually believe them. >>
@_@
Given that SQL Server now outperforms Sybase's product, and provides more features than it, as well as being easier to use, I honestly couldn't care less who they bought the original engine from.
<<
Actually, XENIX itself was not sold to SCO, because they had their own UNIX before XENIX was discontinued, SCO mearly purchased the XENIX business from Microsoft, because the wanted to purchase the CUSTOMER base that Microsoft seem to be sooo willing to ABANDON at the time. >>
XENIX itself *was* sold to SCO. SCO continued to develop (to an extent) and support it. SCO had more than one UNIX; their aim, presumably, was to migrate XENIX users to their own OS -- but they own the copyright and the source code to XENIX. The product was rebranded SCO XENIX, and continued to be updated.
