'''The Santa Cruz Operation, Inc.''' (usually known as '''SCO''',<ref name="pr-names"/> pronounced either as individual letters or as a word) was an American [[software company]], based in [[Santa Cruz, California]], that was best known for selling three [[Unix operating system]] variants for [[Intel]] [[x86]] processors: [[Xenix]], [[SCO UNIX]] (later known as [[SCO OpenDesktop]] and [[SCO OpenServer]]), and [[UnixWare]].

SCO was founded in 1979 by Larry Michels and his son Doug Michels and began as a consulting and Unix porting company.  An early involvement with [[Microsoft]] led to SCO making a product out of Xenix on Intel-based PCs.  The fundamental insight that led to SCO's success was that there was a large market for a standard, [[Open system (computing)|"open systems"]] operating system on commodity microprocessor hardware that would give business applications computing power and throughput that previously was only possible with considerably more expensive minicomputers.  SCO built a large community of [[value-added reseller]]s that would eventually become 15,000 strong and many of its sales to small and medium-sized businesses went through those resellers.  This community was exemplified by the annual [[SCO Forum]] conference, held in a scenic setting that reflected the company's Santa Cruz culture.  SCO also had corporate customers in the replicated sites space, where a SCO-based system was deployed in each of a retail or restaurant chain's stores.

Despite seeing rapid growth in terms of revenues, SCO tended to have high research and development costs and was never consistently profitable either before or after going public in 1993.  SCO bought two former Xenix outfits, the [[Logica#Software Products Group, Rapport, and Xenix|Software Products Group within Logica]] in 1986 and [[HCR Corporation]] in 1990, thereby gaining development offices in [[Watford, England]] and [[Toronto, Canada]].  During the mid-1990s, SCO acquired two further UK companies, [[IXI Limited]] in [[Cambridge]] and [[Visionware]] in [[Leeds]], which led to a suite of client-to-Unix integration products and then the [[Tarantella (product)|Tarantella]] product line.  SCO's operating system technology moved from Xenix to [[System V Release 3]] as reflected by the products [[SCO Open Desktop]] and [[SCO OpenServer]].  In 1995, SCO bought the [[System V Release 4]] and [[UnixWare]] business from [[Novell]] and, in collaboration with several hardware partners, the [[New Jersey]] development office it gained in the deal led a series of enhancements to the UnixWare product aimed at the high-end enterprise and data center spaces.

Beginning in the late 1990s, SCO faced increasingly severe competitive pressure, on one side from Microsoft's [[Windows NT]] and its successors and on the other side from the free and open source [[Linux]].  In 2001, the Santa Cruz Operation sold its rights to Unix and its Unix divisions to [[Caldera Systems]].  After that the corporation retained only its Tarantella product line, and changed its name to [[Tarantella, Inc.]]  Caldera Systems became [[Caldera International]] and then changed its name to [[The SCO Group]], which has created some confusion between the two companies. The company described here is the original Santa Cruz Operation. Although generally referred to simply as "SCO" up to 2001, it is now sometimes referred to as "old SCO", "Santa Cruz", or "SCO Classic" to distinguish it from "The SCO Group" to whom the U.S. trademark "SCO" was transferred.<ref>{{cite web

== Early history ==

=== Origin ===
[[Image:Santa Cruz-10-Universitaet-Cafeteria-1980-gje.jpg|thumb|right|The origins of the company and its culture came in part from the University of California, Santa Cruz, shown here in 1980.]]

SCO was founded in 1979 in [[Santa Cruz, California]], by Larry Michels and his son Doug Michels as a [[computer consulting|computer consulting company]] that focused on both technology and management considerations.<ref name="pate-9ff"/>   Larry Michels, 48 years old at the time,    was an electrical engineer who had gone into the aerospace industry in Los Angeles.<ref name="nb-1992"/>  He had then founded a credit verification company, Credifier Corporation, which he sold to [[TRW Inc.]], for whom he subsequently served as a vice president for ten years.<ref name="scs-larry-obit">{{cite news | url=https://www.newspapers.com/image/92035341/ | title=Stroke Claims SCO's Founder | author-first=Jennifer | author-last=Pittman | newspaper=Santa Cruz Sentinel | date=November 13, 1999 | pages=A1, A14 | via=Newspapers.com}}</ref>  (Larry Michels was first cousin of another technology entrepreneur, [[Allen Michels]].<ref name="nyt-1991"/>)  Towards the end of that time, Michels became head of the Advanced Products Laboratory for [[TRW Electronics]],<ref>{{cite book | url=https://books.google.com/books?id=JcnuAAAAMAAJ&q=%22trw+vidar%22+larry+michels | title=Industrial Research Laboratories of the United States | editor=Jaques Cattell Press <!-- not a person, don't split up --> | publisher=National Research Council | year=1979 | edition=10th | page=552| isbn=9780835211352 }}</ref> and relocated to Santa Cruz to run it remotely from there.<ref name="scs-ms-1989"/><ref name="scs-larry-pd-notice">{{cite news | url=https://www.newspapers.com/clip/78405826/ | title=Remembrances: Notice: Lawrence Michels | newspaper=Santa Cruz Sentinel | date=November 12, 1999 | page=A-10}}</ref>

Unless you approached them as being computers, you didn't end up with anything."<ref name="microtimes"/>  He then left TRW to do management consulting work,<ref name="nb-1992"/> thinking, as he later said, that "if TRW was having so much trouble, it was probably an interesting business [helping companies] go about making these transitions."<ref name="microtimes"/>  As a result of this connection, some have considered The Santa Cruz Operation to have been an offshoot of TRW Vidar.<ref>{{cite web | url=http://www.softpanorama.org/People/Torvalds/Finland_period/xenix_microsoft_shortlived_love_affair_with_unix.shtml | title=XENIX – Microsoft Short-lived Love Affair with Unix | author-first=Nikolai | author-last=Bezroukov | work=Softpanorama | date=July 28, 2019 | access-date=May 27, 2021}}</ref>

Doug Michels, 25 years old at the time,<ref name="nb-1992"/> had graduated from the [[University of California, Santa Cruz]] in 1976 with a degree from their department of computer and information science.<ref name="scs-ms-1989"/>  <!-- TODO did Doug study/use Unix at UCSC?

The two saw some commonalities in their consulting endeavors and decided to join forces to reduce overhead.<ref name="nb-1992"/>  They chose to stay in Santa Cruz both because of the relaxed lifestyle there and because the university would provide a ready supply of technically suitable employees.<ref name="scs-1988"/><ref name="nyt-1991"/>  By some sources The Santa Cruz Operation, Inc. was incorporated in January 1979.<ref>See for instance Doug Michels' Linked In page<!-- https://www.linkedin.com/in/dougmichels/ -->, which gives January 1979 as his start date with SCO.</ref> The name came from Larry Michels' time as head of the TRW advanced research group, when the remote outpost had been known as 'the Santa Cruz operation'.<ref name="scs-ms-1989"/>  The Michelses decided to use that for the name of their new firm,<ref name="scs-ms-1989"/> and the name was retained in the years that would follow because it told people where they were coming from.<ref name="scs-1983"/>

=== Unix porting company ===
[[Image:Downtown santa cruz, cropped.jpg|thumb|left|SCO's first offices were in downtown Santa Cruz, about {{frac|2|5}} of a mile distant along the right side of this viewpoint]]

Offices for the new firm were established at 500 Chestnut Street in the downtown area of Santa Cruz.<ref name="cw-1981"/><ref name="scs-1983"/>  But as Doug Michels conceded in a 2006 interview, in terms of what they would be doing, "We didn't really have an idea."<ref name="doug-video"/><!-- 00:04 -->  Pure consulting work held little ongoing appeal,<ref name="scs-1988"/> and the notion of helping large businesses manage rapid technological change proved difficult in practice.<ref name="microtimes"/>

However, the Michelses soon became intrigued by the [[Microprocessor chronology|microprocessor revolution]] then underway, in which computer systems based on processors such as the [[Intel 8080]] or the [[Zilog Z80]] could be put together much quicker than the [[Minicomputer|minicomputers]] of the past.<ref name="doug-video"/><!-- 00:18 -->  In the consulting work they did, SCO was dealing with various resellers and small time-sharing companies in helping those companies formulate their technology strategies.<ref name="doug-video"/><!-- 01:50, 02:20 --> The people at SCO had, and further acquired, a familiarity with the [[Unix operating system]] and its potential for use in the business world.<ref name="microtimes"/><ref name="pate-9ff"/>  By early 1981, SCO was selling a report analyzing Unix features and availability based on a poll it had taken of over sixty members of the /usr/group association.<ref name="cw-1981">{{cite news | url=https://books.google.com/books?id=NxcYP0D6EBsC&q=%22santa+cruz+operation%22+chestnut+street&pg=PA6 | title=AT&T's 'C' Called Flexible Language | author-first=Brad | author-last=Schultz | newspaper=Computerworld | date=February 23, 1981 | page=6}}</ref>

Moreover, people at SCO realized that since Unix was portable and not controlled by any hardware manufacturer, use of it could allow microprocessor-based system manufacturers to avoid having to develop a proprietary operating system of their own, which they had neither the time nor the expertise to do.<ref name="doug-video"/><!-- 00:45 -->  Accordingly, the company decided to focus on custom jobs of [[porting]] the Unix system and applications that ran on it.<ref name="pate-9ff"/>  [[Eric S.

There had been considerable skepticism in the industry that Unix could ever establish a successful market position on the PC.<ref name="iw-unix-pc"/>  These included beliefs that Unix was inherently large and complex enough that it needed a minicomputer, the platform on which it had been developed, in order to run effectively.<ref name="nb-1992"/> As Larry Michels said in early January 1991, "We had all the problems of being ahead of the market."<ref name="nyt-1991"/>  The company had never been adequately funded, as venture capitalists were unenthused by the idea of Unix on a PC; cash flow problems resulted and the Michelses used much of their personal savings to keep the company in business.<ref name="nyt-1991"/><ref name="nb-1992"/>  A key turning point was when [[Compaq Computer]] began shipping systems with Unix installed and chose SCO to be their provider.<ref name="nyt-1991"/>

Larry Michels tended to focus on the business aspects of the company while Doug Michels focused on technology facets; together they became recognized as pioneers of the Unix-on-PC industry.<ref name="scs-larry-obit"/>  Larry Michels was president of SCO and Doug Michels was, as Larry put it, "the number-two person", usually with the title of executive vice-president, but both employees and outside investors were encouraged to treat the two as an indivisible team.<ref>{{cite news | url=https://www.inc.com/magazine/19900401/5121.html | title=Fathers and Sons | author-first=Ellen | author-last=Wojahn | magazine=Inc. | date=April 1990}}</ref>

Microsoft's level of commitment to Xenix was always viewed with some suspicion within the industry.<ref>{{cite news |author-first=Laurie |author-last=Flynn |date=April 24, 1995 |title=The Executive Computer |newspaper=The New York Times| url=https://www.nytimes.com/1995/04/24/business/information-technology-the-executive-computer.html | page=D4}}</ref>  It later became clear that by the mid-1980s, Microsoft was losing interest in Xenix from their own business perspective,<ref name="esr-art"/> both due to the cost of licensing it from AT&T and because [[MS-DOS]] was rapidly taking off as a product.<ref name="sjvn-2003"/>   <!--TODO Thus SCO ... what was I going to add here? -->

Microsoft's motivation for the purchase has been variously explained as a desire to keep a Xenix technology partner,<ref name="iw-ms-1989"/> as a hedge against the growth of Unix,<ref name="nyt-1991"/> and as a hedge against the [[Open Software Foundation]].<ref name="sjvn-2003"/>  Yet another explanation was the one given by Larry Michels in 1991, making reference to the SCO Unix product then being sold: "The paradox is if you were Microsoft, Open Desktop isn't something you want to see succeed.

In any case, intellectual property rights were not transferred in the 1989 agreement and SCO would continue to pay Microsoft royalties for Xenix and Unix technologies.<ref name="nyt-1991"/>  Not until 1997 was SCO able to reach an agreement with Microsoft that relieved SCO of the obligation to include Microsoft code, and pay royalties on that code regardless of whether it was used or not, in SCO products.<ref name="wsj-1997">{{cite news | author-first=Don | author-last=Clark | title=Microsoft Agrees to Free Software Rival from Paying Royalties on Unix System | newspaper=The Wall Street Journal | date= November 24, 1997 | page=B10 | url= https://www.proquest.com/docview/398649518 | id={{ProQuest|398649518}} }}</ref>  And that only came after SCO filed a complaint against Microsoft for violating [[European Union competition law]], a complaint that was ruled valid by the [[European Commission]].<ref>{{cite news | url=https://www.latimes.com/archives/la-xpm-1997-nov-25-fi-57402-story.html | title=Microsoft Alters Deal to End EU Dispute | agency=Bloomberg News | newspaper=Los Angeles Times | date=November 25, 1997}}</ref>

Needing to create a product from a more recent branch from the Unix family tree, [[UNIX System V#SVR3|Unix System V Release 3]], SCO, together with Microsoft and [[Interactive Systems Corporation]], worked during 1987 and 1988 to develop the [[UNIX System V#SVR3|System V/386 Release 3.2]] version, which adds the ability to run existing Xenix binary applications on System V without requiring recompilation.<ref name="pate-9ff"/><ref name="rosen-etal"/> This capability makes use of the new [[Intel Binary Compatibility Standard]] (iBCS), developed by Intel, AT&T, and SCO.<ref>{{Cite news |title=Binary Unix 386 Standard to Be Revised |author=Scott Mace |newspaper=InfoWorld |date=27 August 1990 |url=https://books.google.com/books?id=7zsEAAAAMBAJ&pg=PT4}}</ref>  The AT&T release of System V/386 Release 3.2 was announced at [[SCO Forum]] in 1988, but further work was needed by SCO to incorporate Xenix device drivers before SCO could release it as a product.<ref>{{cite news | url=https://books.google.com/books?id=iDoEAAAAMBAJ&pg=PA25 | title=AT&T's Unix/Xenix Merged Product Ready for Delivery | author-first=Martin | author-last=Marshall | magazine=InfoWorld | date=August 29, 1988 | page=25}}</ref>

Collectively, Xenix and SCO UNIX became the most installed flavor of Unix due to the popularity of the [[x86]] architecture.  Hardware manufacturers that manufactured Intel-based systems and that resold a SCO operating system on it included not just Compaq but also [[Digital Equipment Corporation|DEC]], [[Tandy Computers]], [[Siemens Nixdorf]], [[Olivetti]], [[Unisys]], and [[Hewlett-Packard]].<ref name="nyt-1991"/>  Especially significant were those systems with multiprocessor capability, such as the [[Compaq SystemPro]],<ref name="nyt-1991"/> for which the SCO MPX multiprocessor extension to SCO UNIX had been delivered in 1990 based on development work that SCO did in conjunction with the firm Corollary, Inc.<ref>{{cite news | url=https://books.google.com/books?id=6sRfQxuIMUEC&pg=RA5-PA6 | title=Multiprocessor extension fans Compaq fires | author-first=Patricia | author-last=Keefe | newspaper=Computerworld | date=July 9, 1990 | page= 70}}</ref> This effort produced the first version of Unix to support the [[symmetric multiprocessing]] capability of Compaq's.<ref name="pate-9ff"/>

The primary market segment for SCO Unix was small businesses, such as real estate offices or florists to take two examples, where specialized dealers who were familiar with a particular application domain built or assembled customized software for that domain and then sold that as a turnkey solution to the business.<ref name="krns-1991"/>  SCO Unix was also used by chains such as [[Radio Shack]] and [[Taco Bell]].<ref name="krns-1991"/>

SCO capitalized on the increasingly prevalent [[Open system (computing)|"open systems" movement]] of the time, which held that a combination of [[interoperability]], [[software portability|portability]], and [[open standard|open software standard]]s should result in computer users should not being locked into any one computer company's product.<ref name="nyt-1991"/><ref name="nb-1992"/><ref name="scs-1992-b"/>  Moreover, Doug Michels became an effective and convincing advocate for the open systems idea.<ref name="nyt-1991"/>  The premise in SCO's case was that an industry standard operating system for industry standard hardware – capable of handling the kind of multi-tasking, multi-user workload that MS-DOS could not – would give customers a compelling offering that previously was thought only possible with considerably more expensive minicomputers.<ref name="nyt-1991"/><ref name="nb-1992"/> By early 1991, ''[[The New York Times]]'' was publishing a profile of SCO based around the notion that it might become "the next Microsoft".<ref name="nyt-1991">{{cite news | url=https://www.nytimes.com/1991/01/04/business/small-software-maker-is-taking-giant-steps.html | title=Small Software Maker Is Taking Giant Steps | author-first=Lawrence M. | author-last=Fisher | newspaper=The New York Times | date=January 4, 1991 | pages=D1, D4}}</ref>

While SCO operating systems were often the basis of [[vertical market software]] offerings by others,<ref name="iw-tandy-1988">{{cite news | url=https://books.google.com/books?id=-j4EAAAAMBAJ&pg=PA32 | title=Tandy Plans Marketing Push for Xenix Products | author-first=Paula S. | author-last=Stone | date=June 6, 1988 | page=32}}</ref> SCO had long desired to create additional [[horizontal market software]] applications for its operating system product as part of further popularizing it.<ref name="krns-1991"/>  Thus SCO had provided some basic applications with Xenix, including database, graphics, a word processor, and a spreadsheet.<ref name="scs-1988"/>

SCO had visions of selling its applications on platforms other than its own.  In late 1988, SCO and Sun Microsystems announced that SCO Office Portfolio would be ported to [[Sun-3 workstation]]s running [[SunOS]].<ref>{{cite news | url=https://books.google.com/books?id=WSBVAAAAMAAJ&pg=RA23-PA13 | title=Industry News: Familiar Software Migrates to Unix | work=Computing News | publisher=University of Michigan Computing Center | date=1988 | page=13}}</ref><!-- also https://link.gale.com/apps/doc/A7019945/ITOF?u=wikipedia&sid=ITOF&xid=5d40cc8d -->  And in mid-1990, SCO made its Word for Unix available for [[AT&T 3B2]] and [[AT&T 6386]] systems.<ref name="pr-word-1990"/><ref name="edge-word-1991"/>

One of the offerings in the SCO Office Portfolio was SCO FoxBase+, a version of [[FoxBase]] that is explicitly purposed as a look-alike to the popular [[dBase III]] database software for MS-DOS.<ref name="iw-otherside-1989"/><ref name="iw-word-1990"/>  And even SCO's advertisements had called SCO Professional a "workalike" of the popular [[Lotus 1-2-3]] spreadsheet.<ref name="cw-portfolio-ad">{{cite news | url=https://books.google.com/books?id=TLCrPe3QfssC&pg=PA36 | title=Go Ahead, Make Your Day | newspaper=Computerworld | date=August 7, 1989 | page=36}} Advertisement; note also copyright notices at bottom.</ref>  This resulted in problems when, in July 1990, [[Lotus Development Corporation]] sued SCO for copyright infringement, as one of several such actions that Lotus took against its imitators and competitors.<ref>{{cite news | url=https://www.nytimes.com/1990/07/03/business/lotus-sues-2-on-copyright-violation.html | title=Lotus Sues 2 On Copyright Violation | author-first=John | author-last=Markoff | newspaper=The New York Times | date=July 3, 1990 | page=D1}}</ref>  The suit was settled out of court a year later; in a victory for Lotus, SCO agreed to stop all sales and licensing of SCO Professional and instead recommend that customers use 1-2-3.<ref>{{cite news | url=https://www.nytimes.com/1991/06/18/business/company-news-lotus-settles-suit-with-santa-cruz.html | title=Company News: Lotus Settles Suit With Santa Cruz | agency=Reuters | newspaper=The New York Times | date=June 18, 1991 | page=D4}}</ref><ref>{{cite news | author-last=Ould | author-first=Andrew | title=Win over SCO strengthens Lotus' hand in Borland suit | magazine= PC Week | date=June 24, 1991 | pages= 163ff | via= Gale General OneFile <!--(accessed May 22, 2021).--> | url= https://link.gale.com/apps/doc/A10897232/ITOF?u=wikipedia&sid=ITOF&xid=154ec848}}</ref>

In the end, SCO had neither the market share nor the sales ability to compete on applications with the major players in that area such as Microsoft and Lotus.<ref name="cweek-1994"/>  Accordingly, staffing level and expenses for application work were sharply reduced in 1991,<ref name="krns-1991"/> and again in 1993–94.<ref name="cweek-1994"/>  The final version of Microsoft Word for SCO Unix, for instance, was 5.1.1; it was eventually withdrawn as a product by SCO in 1996.<ref>{{cite web | url=https://www.scosales.com/ta/kb/110788.html | title=Microsoft Word for SCO UNIX terminates with a 'Signal 11 received' error when you try to save a document | work=SCO TA #110788 | publisher=Computer Business Consultants | date=January 26, 2000 | access-date=May 20, 2021}}</ref>

===ACE and near insolvency===
Besides Microsoft, venture capitalists owned about 20 percent of SCO by 1991, meaning that the Michelses owned a majority of the company,<ref name="nyt-1991"/><ref name="nb-1992"/> although by 1993 the Michelses' share was stated as being about one-third.<ref name="scs-adv-1993"/>  These venture capital firms included [[Morgan Stanley]], [[Accel Partners]], [[Chancellor Capital]], and [[Wolfensohn & Company]].<ref name="scs-adv-1993"/>

During the late 1980s and early 1990s, analysts said that, given its revenue SCO should be more profitable than it was.<ref name="iw-ms-1989"/>  Indeed, SCO had never been able to show profits on a consistent basis;<ref name="krns-1991"/> through the end of fiscal 1991 SCO had accumulated a total loss of $31 million over its entire existence.<ref name="scs-adv-1993"/> SCO had high staffing levels, with for instance the $106 million revenue for 1990 going along with 1,300 employees, which was twice the level a typical software company of its era would have had.<ref name="nyt-1991"/>  One analyst said that SCO "is run like a university, a family-run university, not a company."<ref name="nyt-1991"/> Commenting on the company's efforts to write applications for Unix themselves, another analyst said "It's a company that attacks in all directions."<ref name="krns-1991"/> In part due to this kind of criticism, the Michelses said in late 1990 that they saw significant downsides to going public and preferred to remain private.<ref name="nyt-1991"/><ref name="nb-1992"/>  One former employee recalled that Larry Michels "ran SCO like it was a downhill skier racing out of control. He liked to think the company was literally like that – the fastest guy was always a little bit out of control. SCO was always a little out of control."<ref name="scs-larry-obit"/>

The late 1980s saw considerable interest in [[Reduced instruction set computer|RISC]]-based processor architectures in comparison to Intel's existing [[Complex instruction set computer|CISC]]-based approach, and there was particular interest in the [[R3000]] and [[R4000]] processors from [[MIPS Computer Systems]].<ref name="nyt-ace-1991"/>  Major hardware vendors such as [[Digital Equipment Corporation]] were switching over to RISC-based systems.

In April 1991, the [[Advanced Computing Environment]] initiative was announced.<ref name="nyt-ace-1991"/>  There were a number of companies involved, but in term of the major players, it consisted of Compaq, Microsoft, MIPS Computer Systems, DEC and the Santa Cruz Operation.<ref name="reg-ace-2013">{{cite news | url=https://www.theregister.com/2013/08/20/nt_at_20 | title=Windows NT: Remember Microsoft's almost perfect 20-year-old? | author-first=Andrew | author-last=Orlowski | work=The Register | date=August 20, 2013}}</ref>  It had the goal of building the next generation commodity computing platform around the MIPS processor.<ref name="nyt-ace-1991">{{cite news

==Later history==
=== The Novell–SCO–HP deal of 1995 ===

Novell and then SCO inherited the cutout. For some time after the Novell–SCO–HP deal closed, all three companies were sharing the same office space in Florham Park, New Jersey.  In order to demark which corridors were SCO's, the Stroustrup cutout was put up with a  hat, a bolo tie-with-badge, and a SCO business card saying "{{not a typo|SCOland}} Sheriff".]]

As Doug Michels later reflected in 2006, SCO seized on the idea of buying the Unix business from Novell for three reasons: "for one, we got all the talent from Bell Labs that had created Unix; two, we got the moral authority around Unix; and three, we got rid of all the crazy historical licensing problems" dating from Unix's origins within AT&T.<ref name="doug-video"/><!-- 14:30 -->  In order to reduce the price to SCO, part of the deal was that SCO agreed to pay a royalty stream back to Novell of UnixWare sales.<ref name="doug-video"/>
 
By December 1995, there were already some indications that the three-way arrangement was not working out as had been initially advertised.<ref name="IW_Gemini_Whitebox_1995"/>  The computer industry was not sure that SCO could handle being the primary Unix shepherd.<ref name="IW_Confusing_2003"/>  The HP project, code-named "White Box", focused on making a hybrid environment out of the SRV4.2-based Gemini and the SVR3.2-based HP-UX, but that effort faced major technical hurdles.<ref name="IW_Gemini_Whitebox_1995"/>

"White Box" became the [[3DA]] effort, the purpose of which was to unify OpenServer, UnixWare, and [[HP-UX]] in some way to produce a resulting product would then become the de facto Unix standard for both existing [[IA-32]] systems and the upcoming [[IA-64]].<ref name="pr-threewaydeal">{{cite press release |title= HP, Novell and SCO To Deliver High-Volume UNIX OS With Advanced Network And Enterprise Services |publisher= Novell; SCO; Hewlett-Packard |date= September 20, 1995  |url= http://www.novell.com/news/press/archive/1995/09/pr95220.html  |access-date=

As an ''[[InformationWeek]]'' story later wrote, the three-way deal had been a "complicated plan" that was "confusing from the start".<ref name="IW_Confusing_2003"/>  The terms of the deal between Novell and SCO  were uncertain enough that an amendment to the agreement had to be signed in October 1996.<ref name="IW_Confusing_2003"/> (Even that was not clear enough to preclude an extended legal battle between Novell and [[The SCO Group]] during [[SCO-Linux disputes]] of the 2000s,<ref name="IW_Confusing_2003"/> a battle that The SCO Group eventually lost.<ref>{{cite news |url=http://www.sltrib.com/news/ci_14786202 |title=Decision in SCO-Novell case ripples beyond Utah |author-first=Tom |author-last=Harvey |newspaper=The Salt Lake Tribune |date=March 30, 2010 }}</ref>)

=== "Gemini" and the UDK ===
Meanwhile, SCO focused on "Gemini", the task of combining the OpenServer and UnixWare product lines on 32-bit systems. The fundamental idea behind the Gemini was that SCO could merge OpenServer 5 and UnixWare 2 in a way that would satisfy the requirements of both small businesses and large enterprises and thus keep the existing customer base that SCO had with OpenServer while entering the enterprise space with UnixWare.<ref name="cnet-uw7-1997">{{cite news | url=https://www.cnet.com/news/sco-readies-merged-os/ | title=SCO readies merged OS | publisher=CNET | date=November 11, 1997}}</ref>

One consequence of the UnixWare acquisition was that the New Jersey office of Novell had a languages and development tools group with more advanced technology than what SCO Canada had been working with, including a C++ compiler based upon the [[Edison Design Group]] front-end,<ref name="c++eh-1998">{{cite journal | title=Optimizing away C++ exception handling | last=Schilling | first=Jonathan L. | journal=ACM SIGPLAN Notices | volume=33 | issue=8 | date=August 1998 | pages=40–47 | doi=10.1145/286385.286390 | s2cid=1522664 | doi-access=free }}</ref><ref name="pr-udk-1997"/> and that made the SCO Canada engineering staff largely redundant once the Novell deal was closed.

SCO management was intent on selling UnixWare through OEM deals with hardware manufacturers aiming at the enterprise market, and towards this end in 1996 they announced the "Big E" initiative that would standardize UnixWare as the operating system on these systems and that would attract independent software vendors to make their products available on such systems.<ref name="ci-BigE-1996">{{cite news | title=Santa Cruz Operation Chief Mohan Explains How He Will End Days of Underachivement | work= Computergram International | date= August 30, 1996 <!--, CGN08300008. --> | via=Gale General OneFile <!-- (accessed April 29, 2021). --> | url=https://link.gale.com/apps/doc/A18639022/ITOF?u=wikipedia&sid=ITOF&xid=2c24ac2b | author-first=Nick | author-last=Patience}} <!-- also visible at https://techmonitor.ai/technology/sco_chief_says_he_will_end_days_of_underachievement --></ref>  Hardware vendors already supporting UnixWare 7 included IBM, HP, Compaq, and Tandem, despite some of them offering their own Unix flavors on their high-end RISC systems.<ref name="nw-uw7-1998">{{cite news | url=https://books.google.com/books?id=fhsEAAAAMBAJ&pg=PA60 | title=SCO makes run at glass house | author-first=James | author-last=Niccolai | author2-first=Marc | author2-last=Songini | magazine=Network World | date=March 16, 1998 | pages=1, 60}}</ref>  In particular, SCO had deals with IBM to sell UnixWare on the [[IBM Netfinity]] system.<ref name="ci-earnings-1999"/>

The idea of the purchase from Caldera Systems' perspective is that it would gain access to SCO's large  VAR channel; the value of such channels was well known to former Novell chief [[Ray Noorda]], whose [[Canopy Group]] was funding Caldera Systems.<ref name="slt-cald-2000"/>  The announcement that SCO was selling its Unix assets to a Linux distribution company represented, in the view of Eric Raymond, the completion of the move from the commercial Unix industry to the open-source movement.<ref name="esr-art"/>  From Doug Michels' later perspective, the problem with Linux was not that it was open source and free itself, but rather that in August 1999, during the [[dot-com boom]], the Linux company [[Red Hat]] had been able to get $400 million during their IPO and was not expected to make a profit anytime soon, while SCO was an established public company closely watched by the stock market that was expected to make a profit and had only around $50 million in cash.<ref name="doug-video"/><!-- 15:30 -->  By this time, the SCO stock price was down around 2{{frac|1|2}}.<ref name="scs-parting"/>  Thus when the chance came to merge with Caldera Systems, which was in a generally similar position as Red Hat although with less cash, SCO took it.<ref name="doug-video"/><!-- 17:30 -->

In August 2002, [[Caldera International]] renamed itself [[The SCO Group]] since the SCO Unix products were still their greatest source of revenue due to the large installed base they had. That entity soon started the [[SCO-Linux controversies]].

From its earliest days through to its last ones, The Santa Cruz Operation was known for reflecting the casual ambience of its namesake town.<ref name="scs-parting"/>  Dress was casual to the point where some staffers went barefoot.<ref name="scs-1983"/>   There was beer in the office, end-of-day meetings held on Encinal Street roofs, and an outdoor hot tub at the Mission Street office (dating from the facility's previous existence as a holistic health clinic) that was used during the day or for late-night, after-work parties.<ref name="scs-spirit"/><ref name="patch-heyday-2012"/>  One former employee said years later of her experience there, "It was a family.

=== SCO Forum ===
{{main|SCO Forum}}
Beginning in 1987, SCO hosted an annual Summer conference for the international Unix community. Called [[SCO Forum]], it was held on the [[University of California, Santa Cruz]]'s scenic [[redwood]]-forested campus overlooking [[Monterey Bay]], drew some 2000–3000 attendees, and lasted for much of a week.<ref name="scs-1991">{{cite news | url=https://www.newspapers.com/image/66415565/?terms=%22tower%2Bof%2Bpower%22%2B%22sco%2Bforum%22 | title=Corporate cultures splash at SCO industry forum | author-first=Guy | author-last=Lasnier | newspaper=Santa Cruz Sentinel | date=August 21, 1991 | page=B5 | via=Newspapers.com}}</ref><ref name="scs-1992-b"/><ref name="scs-1995-b">{{cite news | url=https://www.newspapers.com/image/92420680 | title=SCO Forum gets bigger each year | author-first=Steve | author-last=Perez | newspaper=Santa Cruz Sentinel | date=August 24, 1995 | page=C3 | via=Newspapers.com}}</ref>

=== Palookaville webcasts ===
Following the first live Internet concert in 1994, SCO continued in that tradition by sponsoring and producing a series of live Internet webcasts from the popular Santa Cruz night club Palookaville. These webcasts demonstrated the use of UnixWare 7 as a real-time audio and video webcasting server utilizing [[RealAudio]] and [[RealVideo]] technologies from [[RealNetworks]].<ref>{{cite web

=== Trapping a hacker ===
SCO was a target of one of the most publicized [[security hacker]]s of the 1980s and 1990s, [[Kevin Mitnick]], who broke into the company's systems in 1987.<ref name="nyt-hacker-1994">{{cite news | url=https://www.nytimes.com/1994/07/04/us/cyberspace-s-most-wanted-hacker-eludes-fbi-pursuit.html | title=Cyberspace's Most Wanted: Hacker Eludes F.B.I.

=== SCO Follies ===
From 1985 to 2001, the company hosted a [[Winter Solstice]] party at the [[Cocoanut Grove (Santa Cruz)|Cocoanut Grove]] in Santa Cruz featuring a live musical show known as "The SCO Follies". This was a fully scripted and produced satire skewering SCO management and the high-tech industry. It featured live action, musical numbers, and videos.<ref>{{cite web |url=https://www.youtube.com/profile_play_list?user=motibloc |title=motibloc's Playlists |access-date=May 14, 2008 |author-first=Stephen |author-last=Marino |publisher=YouTube}}</ref> On September 22, 2012, the SCO Alumni Association hosted the SCOGala Reunion party at the Cocoanut Grove, which included the first SCO Follies since 2001. Some 500 former employees, friends, and family attended the event.

|-
| 1988 || ''Cheers'' || Sometimes you want to go where no-one knows your login name.

| 1989 || ''Larry Wants an Ad'' || Exasperated with Bruce Steinberg's hairbrained ideas, Larry Michels asks employees to submit concepts for a new ad campaign.
|-
|- valign="top"
| 1990 || ''Late Night with Doug Michels'' || SCO licenses the "Late Night" format from GE with Doug as host. Guests include the XENIX Colonel, Michael J. Foxplus (promoting "Backup to the Future II"), SCO's own Princess of Purple, and (direct from the mail room) "Elvis".
|-
|- valign="top"
| 1991 || ''KODT'' || SCO launches a cable television channel that requires a telethon to raise funds for the equally cash-strapped organization (operating under the banner of "almost" public television). 
|-
|- valign="top"
| 1992 || ''Archaeological Dig'' || The year is 2100 and the world has only recently recovered from a catastrophic era known as "The Corporate Wars". Drs. Dave Loman and Jane Greenleaf are recovering artifacts from the original SCO site in New Santa Cruz. The archaeologists are working under the supervision of an overbearing AI known as the NED 9.0.1 Project Management System, and Michelle Michels, descendant of the founders of SCO. With a little hacking, a kinder, wackier NED makes for a much less stressful work environment.
|-
|- valign="top"
| 1993 || ''How to Succeed in the Software Business'' || Job applicant Grace Hopper joins the company via social engineering. With the help of a book on the software business, Grace hopscotches across the SCO org chart with stints in Manufacturing, Support, Engineering, Sales, and Marketing. Meanwhile, VP and co-founder Doug Michels is rescued from a car crash and imprisoned by a deranged ex-SCO employee named Annie Wilkes. Grace is ultimately made CEO, but turns it down for a better job. This show includes the infamous "Die Hard" video by late Follies action director Peter (Israel) Rosencrantz. In the current climate, it's hard to picture a CEO giving permission for employees to parade through the building carrying automatic weapons, let alone appearing in the video himself. But Swedish-born Lars Turndal sat for an hour with guns trained on him by some wacky Americans as if he'd been doing it all his life.
|-
|- valign="top"
| 1994 || ''The Phantom of the Operation'' || Software engineer Eric T. Claudin runs afoul of evil VP Edwin Vincent Leach, who is bent on SCO's destruction. Disfigured in a hot tub "accident" arranged by Leach, Eric becomes the Phantom, a dark figure obsessed with saving the firm. Once again, then-CEO Lars Turndal proved he was a real sport and consented to appear in his second (and last) video, one that roasted the executive team for trying to censor the Usenet feed. Brian Moffet produced the stained-glass style panorama that opens the show. 
|-
|- valign="top"
| 1995 || ''FCS Can Wait'' || For the uninitiated, FCS is "First Customer Ship," the magic goal of the product development cycle. Based on the films "Here Comes Mr. Jordan" and Heaven Can Wait," Engineering manager Jo Pendleton is hurled into the great void ahead of schedule. Bodies must be swapped and Heaven & Earth must be moved so that Jo can complete her project of a lifetime, "SCO DoomBugger".
|-
|- valign="top"
| 1996 || ''UNIX Won't Die'' || After a series of high-profile incidents involving glitches in the UNIX operating system (namely Apollo 13, Three Mile Island, and the Exxon Valdez), James Bond tracks the SPECTRE of his nemesis Ernst Stavro Blofeld into the hallways of SCO. Along for the ride is the mysterious Tilly Masterson (sister of the woman who was suffocated in paint by the nefarious Goldfinger). Software engineer Fox Mulder and Dana Sculley ("a schmuck from Legal") have stumbled onto the UNIX plot and are suspicious of Bond's presence.  This show was the first to include digital compositing (a couple of laser beams and explosions). These early steps were taken on a Miro DC20 video card and Adobe Premiere purchased with pooled funds. Bill Welch created these effects and Mike Almond provided the opening Star Wars animation using Caligari TrueSpace. Thereafter, nearly all the effects for Follies were created digitally.
|-
|- valign="top"
| 1997 || ''Taming of the CEO'' || A Shakespearean romp where Viola Murch, a top female director who despairs of ever becoming a VP, decides to disguise herself as a man. She learns that the top floor is a far stranger place than she imagined. This show included a mock preview for a show called "Sliders" about parallel SCO universes. This marked the full use of digital effects and compositing. Mike Almond was responsible for creating such 3D items as a phalanx of Imperial Stormtroopers and a streaking Millennium Falcon.
|-
|- valign="top"
| 1998 || ''A Solstice Carol'' || The story of Ezekiel Kludge, a crusty longtime SCO manager who re-discovers the true meaning of SCO.
|-
|- valign="top"
| 1999 || ''The Wizard of OCS'' || IBM engineering manager Dorothy Gale is transported into the wacky world of OCS, where she meets a Marketeer who wants to lose his brain, A Salesman who wants to get rid of his heart, and an Engineer who wants to get rid of his life.
|-
|- valign="top"
| 2000 || ''Willy Wonka and the Software Factory'' || 
Support specialist Charlotte Bucket dreams of visiting SCO's Software Factory and Willy Wonka, the "Chief Geek" who no-one has seen for years. It's an adventure populated with Corpa Lorpas, Waffling Precompensators, Paleoatavistic Patch Pellucidators, and Everlasting Spamstoppers. Not to mention Fizzy Linux stocks. And some arrogant, selfish, and greedy adult children get their comeuppance as well.
|-
|- valign="top"
| 2001 || ''Fiddler on the 425 Roof'' || The "final" SCO Follies occurred shortly after Caldera Systems purchased the Santa Cruz Operation. Thus the show's theme is change, with Caldera Systems as the Cossacks. The show opens with the "Dawn of Spam" sequence adapted from Stanley Kubrick's classic odyssey. The mood of the "Linux Company" finale was subsequently overturned when the radically downsized, later-named "SCO Group" turned against Linux. 
|-
|- valign="top"
| 2012 || ''Raiders of the Lost Archive'' || When two members of a secret SCO organization are murdered, the SCOllegium assigns a team of ex-SCOites to find out who is responsible.

== Alliances ==
[[Image:SCO Partner Conference 2000 at Stratford-upon-Avon Moat House.jpg|thumb|right|The SCO Partner Conference was a yearly conference held for Santa Cruz Operation partners in the United Kingdom and sometimes elsewhere. The 2000 edition took place at a hotel in Stratford-upon-Avon with the SCO flag flying in front of it.]]

SCO was a primary partner in several industry alliances, intended to promote SCO operating system technology as a de facto standard for emerging hardware platforms.  The most notable of these were:

* [[Advanced Computing Environment|The ACE Consortium]]: Founded by [[Compaq]], [[Microsoft]], [[MIPS Computer Systems]], [[Silicon Graphics]], [[Digital Equipment Corporation]], and SCO in 1991, to drive the next generation of PCs powered by the [[Advanced RISC Computing]] Specification (ARC)
* [[3DA]]:  Formed by SCO and [[Hewlett-Packard]] in 1995, to define the standard Unix for [[IA-32]] and later [[IA-64]] systems
* [[Uniform Driver Interface]]:  Led by SCO and with work starting in 1997, the UDI project sought to establish an OS-neutral and platform-neutral portable interface for writing [[device driver]]s.  The UDI project had the backing of Intel, HP, IBM, Compaq, Sun, and others. 
* [[Project Monterey]]:  Formed by SCO, IBM, [[Sequent Computer Systems|Sequent]] and Intel in 1998, to define the standard UNIX for IA-64 systems.  Also intended to merge some of the proprietary Unix products afloat at the time.<ref name="esr-art"/>

None of these alliances were ultimately successful.

SCO was also part of 1993's [[Common Open Software Environment|COSE]] initiative, a more successful and broadly supported initiative to create an open and unified UNIX standard.

SCO was a founding member of [[86open]] (1997–1999), hosting the first meeting of the Unix on Intel standards effort.
