Their commercial development came in work by Burroughs ( later Unisys ), Convex Computer ( later Hewlett-Packard ), Honeywell Information Systems Italy ( HISI ) ( later Groupe Bull ), Silicon Graphics ( later Silicon Graphics International ), Sequent Computer Systems ( later IBM ), Data General ( later EMC ) and Digital ( later Compaq, now HP ) during the 1990s.

The Digital Display Working Group ( DDWG ) was organized by Intel Corporation, Silicon Image, Inc., Compaq Computer Corp., Fujitsu Limited, Hewlett-Packard Company, International Business Machines Corp., and NEC Corporation.

Prior to joining Nvidia, Mark Kilgard worked at Compaq and Silicon Graphics.

Compaq, already an Intel customer, decided to phase out Alpha in favor of the forthcoming Hewlett-Packard / Intel Itanium architecture, and sold all Alpha intellectual property to Intel in 2001, effectively killing the product.

In 2000, major companies such as IBM, Apple, and Compaq ( now merged with Hewlett-Packard ) decided to discontinue their involvement with COMDEX to allocate resources more efficiently.

When IBM announced the IBM PC in 1981, other companies such as Compaq decided to offer clones of the PC as a legal reimplementation from the PC's documentation or reverse engineering.

Hewlett-Packard purchased Compaq later that same year, continuing development of the existing product line until 2004, and promising to continue selling Alpha-based systems, largely to the existing customer base, until October 2006 ( later extended to April 2007 ).

Microsoft made an offer in 1994 where IBM would receive the same terms as Compaq ( the number one PC manufacturer at the time ) for a license of Windows 95, if IBM ended development of OS / 2 completely.

" During development, there was a build for the Alpha which was abandoned some time after RC1 after Compaq announced they had dropped support for Windows NT on Alpha.

By the time OSF stopped development of OSF / 1 in 1994, the only major UNIX system vendor using the complete OSF / 1 package was Digital, which rebranded it Digital UNIX ( later known as Tru64 UNIX after Digital's acquisition by Compaq ).

The iPAQ was developed by Compaq based on the SA-1110 " Assabet " and SA-1111 " Neponset " reference boards that were engineered by a StrongARM development group located at Digital Equipment Corporation's Hudson Massachusetts facility.

With the acquisition of Compaq by Hewlett-Packard, HP discontinued the Jornada line of Microsoft Windows powered Pocket PCs, moving development and marketing of Pocket PCs to the iPAQ line.

For a time, a commercial compiler called CM3 maintained by one of the chief implementors prior at DEC SRC who was hired before DEC being sold to Compaq, an integrated development environment called Reactor and an extensible Java Virtual Machine ( licensed in binary and source formats and buildable with Reactor ) were offered by Critical Mass, Inc., but that company ceased active operations in 2000 and gave some of the sources of its products to elego Software Solutions GmbH.

Other companies involved in the development of SuperDisk included Compaq and OR Technology.

To accelerate PCI-X adoption by the industry, Compaq offered PCI-X development tools at their Web site.

Compaq Research also published a software development kit for the unit, which enabled users to develop a variation of tools, drivers and applications for many different operating systems.

The technique probably first appeared with the development of CEMM, included with Compaq DOS 3. 31 in 1987.

Compaq claims that Vesta is a mature system and is the result of over 10 years of research and development at the Compaq / Digital Systems Research Center.

* Conectiva Linux Server ( Compaq Alpha )-May 1999

Compaq Alpha 21264C.

The Alpha architecture was sold, along with most parts of DEC, to Compaq in 1998.

The success of this initial processor version was limited to replacing PA-RISC in HP systems, Alpha in Compaq systems and MIPS in SGI systems, though IBM also delivered a supercomputer based on this processor.

* Alpha, used in single-board computers, workstations, servers and supercomputers from Digital Equipment Corporation, Compaq and HP, discontinued as of 2007.

Servers use those processors and other readily available non-x86 processor choices, including the Sun Microsystems UltraSPARC, Fujitsu SPARC64 III and later, SGI MIPS, Intel Itanium, Hewlett Packard PA-RISC, Hewlett-Packard ( merged with Compaq which acquired first Digital Equipment Corporation ) DEC Alpha, IBM POWER and Apple Computer PowerPC ( specifically G4 and G5 series, as well as earlier PowerPC 604 and 604e series ) processors.

In 1998, Compaq also acquired the much larger Digital Equipment Corporation and inherited its DEC Alpha RISC servers with OpenVMS and Tru64 Unix customer bases.

But in 2001, Compaq terminated all Alpha engineering investments in favor of the unproven Itanium microprocessors.

The combination of Quadrics and Alpha 21264 ( EV6 ) microprocessors proved very successful, and Digital / Compaq rapidly became one of the world's largest suppliers of supercomputers.

The microprocessor was never released, since the Alpha line of microprocessors was discontinued shortly before HP acquired Compaq which had in turn acquired DEC. Dean Tullsen's work was also used to develop the Hyper-threading ( Hyper-threading technology or HTT ) versions of the Intel Pentium 4 microprocessors, such as the " Northwood " and " Prescott ".

It was pursued once again in the mid-90s for the Alpha product line, but then abandoned due to the fragmentation of the company and subsequent sale to Compaq.

Intel developed QPI at its Massachusetts Microprocessor Design Center ( MMDC ) by members of what had been DEC's Alpha Development Group, which Intel had acquired from Compaq and HP.

SGI was part of the Advanced Computing Environment initiative, formed in the early 1990s with 20 other companies, including Compaq, Digital Equipment Corporation, MIPS Computer Systems, Groupe Bull, Siemens, NEC, NeTpower, Microsoft and Santa Cruz Operation.

* ACE-Founded by Compaq, Microsoft, MIPS Computer Systems, Digital Equipment Corporation, and SCO in 1991 to drive the next generation of PCs

The consortium was announced on the 9th of April 1991 by Compaq, Microsoft, MIPS Computer Systems, Digital Equipment Corporation, and the Santa Cruz Operation.

By the time he started the Pentium project, a large number of established and new players, including the AIM consortium ( a consortium led by Apple, IBM and Motorola ) an Advanced Computing Environment ( ACE ) consortium formed in 1991 and led by Compaq, Microsoft, DEC, and MIPS Technologies, Inc, and a consortium by Sun Microsystems ( which comprised companies like Sun, Fujitsu, Philips, Tatung and Amdahl ), using superior RISC ( Reduced Instructions Based Computing ) had all begun aggressively working on their big idea for the PC industry and these projects seriously threatened Intel ’ s dominance in the segment.

The expected layoffs at Compaq and HP, 8500 and 9000 jobs, respectively, would leave the combined company with a workforce of 145, 000.

Plus there were significant cultural differences between HP and Compaq ; which made decisions by consensus and rapid autocratic styles, respectively.

In April 1999, Compaq announced that Tru64 UNIX 5. 0 successfully ran on Intel's IA-64 simulator.

In 2002, Be Inc. sued Microsoft claiming that Hitachi had been dissuaded from selling PCs loaded with BeOS, and that Compaq had been pressured not to market an Internet appliance in partnership with Be.

Compaq Computer Corporation was a company founded in 1982, that developed, sold and supported computers and related products and services.

Compaq produced some of the first IBM PC compatible computers, being the first company to legally reverse-engineer IBM Personal Computer.

Struggling in the aftermath of the dot-com bubble bust, Compaq was acquired for US $ 25 billion by HP in 2002.

The Compaq brand remained used by HP for lower-end systems.

Murto departed Compaq in 1987, while Canion ( President and CEO ) and Harris ( SVP of Engineering ) left under a shakeup in 1991 that saw Eckhard Pfeiffer appointed President and CEO.

Early Compaq logo.

Compaq was founded in February 1982 by Rod Canion, Jim Harris and Bill Murto, three senior managers from semiconductor manufacturer Texas Instruments.

The first Compaq PC was sketched out on a table napkin by Ted Papajohn while dining with the founders in a Houston restaurant.

Compaq PortableIn November 1982 Compaq announced their first product, the Compaq Portable, a portable IBM PC compatible personal computer.

The Compaq Portable was one of the progenitors of today's laptop ; some called it a " suitcase computer " for its size and the look of its case.

The Compaq Portable was the first in the range of the Compaq Portable series.

Compaq was able to market a legal IBM clone because IBM mostly used " off the shelf " parts for their PC.

The only part which had to be duplicated was the BIOS, which Compaq did legally by using clean room reverse engineering at a cost of $ 1 million.

On June 28, 1984 Compaq released the Compaq Deskpro, a 16-bit desktop computer using an Intel 8086 microprocessor running at 7. 14 MHz.

It was considerably faster than an IBM PC and was, like the Compaq Portable, also capable of running IBM software.

It was Compaq's first non-portable computer and began the Compaq Deskpro line of computers.

When Compaq introduced the first PC based on Intel's new 80386 microprocessor, the Compaq Deskpro 386, in 1986, it marked the first CPU change to the PC platform that was not initiated by IBM.
