Having abandoned its founding business of manufacturing mainframe computers, Amdahl Corporation has positioned itself in the early 21st century as a developer and implementer of information technology systems and services, and enterprise-level software, and as a provider of professional and consulting services. As an adjunct to its services businesses, the company, a wholly owned subsidiary of Japan's Fujitsu Limited, continues to offer its customers computer servers and storage systems. Among Amdahl's subsidiary operations are DMR Consulting Group, Inc., which focuses on e-consulting services and business solutions for both large corporations and Internet startups; Fujitsu Software Technology Corporation, which provides comprehensive software solutions in various areas of data storage; Fujitsu Technology Solutions, Inc., the unit that handles the company's operations in the areas of servers and storage systems; and trustedanswer.com, a provider of outsourced customer service and customer support services.

Amdahl Corporation was founded on October 19, 1970, in Sunnyvale, California, by Gene M. Amdahl. Born in 1922 in South Dakota, Amdahl left his home state to pursue a doctoral degree in theoretical physics. With a knowledge of electronics gained in the Navy and a familiarity with computer programming garnered from a brief course, Amdahl designed and helped construct an early computer known as the WISC (Wisconsin Integrally Synchronized Computer).

In 1952 Amdahl joined IBM and became chief designer of the IBM 704 computer, which was released in 1954. In 1955 Amdahl and other systems designers began conceptualizing a new computer for IBM, which they christened the Datatron. IBM's Stretch, also known as the IBM 7030, was an outgrowth of the Datatron, a computer using new transistor technology. The name Stretch was not an acronym, but rather stood for 'stretching the limits of computer technology development.' Although Stretch was a financial failure for IBM, it was valuable as the precursor to the successful IBM System 360. In 1956 Amdahl left IBM; he worked at two other high-technology firms before returning to IBM four years later. Amdahl later became the principal architect for the phenomenally successful System 360, which was introduced in 1964.

Amdahl was appointed an IBM fellow, and was thus free to pursue his own research projects. In early 1969, while director of IBM's Advanced Computing Systems Laboratory in Menlo Park, California, he began to investigate the company's cost-pricing cycle as it applied to a large computer they were developing. His team concluded that to make the computer pay for itself, IBM would also have to market two scaled-down versions of the advanced technology. IBM management insisted that Amdahl stay with the original plan to create only one large processor, while Amdahl recommended that they shut down the laboratory. The laboratory was closed in the spring of 1969.

Over the following few months, Amdahl reviewed the policies that prevented IBM from aiming at the high end of computer development and presented his analysis to IBM's top three executives. Although the officers agreed with his analysis, they maintained that it would not be in IBM's best interest to change direction. Amdahl decided to strike out on his own.

Amdahl submitted his resignation to IBM for the second time in September 1970 and founded Amdahl Corporation just a few weeks later. Amdahl took none of IBM's technical personnel with him when he left; he was joined only by young financial specialist Ray Williams and two secretaries. Amdahl and Williams determined that they would need between $33 million and $44 million to see a product to completion (in fact, it took $47.5 million). They had chosen a difficult year for raising money, as new capital gains taxes and an advancing recession made venture capital scarce. Amdahl and Williams first took their business plan to investment bankers, who rejected their proposal because they felt that Amdahl Corporation could not effectively challenge IBM. The pair eventually received $2 million from Heizer Corporation, venture capitalists in Chicago, the day after spending the last of their own investment.

At the same time, three other young California computer companies--MASCOR (Multiple Access Systems Corporation, which was started by staff members who left IBM after the closing of the Advanced Computing Systems Laboratory), Berkeley Computers, and Gemini Computers--had gone bankrupt. Many of their employees joined Amdahl Corporation, forming an impressive technical team.

During Amdahl Corporation's first eight months, it continued the search for more capital. The needed funds came from Fujitsu Limited, a leading Japanese computer manufacturer, which suggested a joint development program and licensing under Amdahl's patents. This 1971 agreement was accompanied by the $5 million investment that Amdahl needed to complete its second phase of development.

In 1972 Nixdorf Computers, a leading German computer manufacturer, agreed to invest $6 million if Nixdorf could represent Amdahl in Europe. Fujitsu also increased its investment, and U.S. investors began to appear. Amdahl amassed a total of $20 million to build a prototype computer and a production facility.

Also in 1972, IBM announced the debut of the 370, its first computer with virtual memory, a flexible, advanced memory technology. Amdahl had been developing a computer like the IBM 370, but without virtual memory, and IBM's introduction forced Amdahl to scrap its initial design.

Amdahl Corporation decided to offer stock publicly in early 1973, but could not find an underwriter. The company then experienced delays with the Securities and Exchange Commission until 1974, by which time the stock market had declined, so Amdahl returned to the private market.

In August 1974 Eugene R. White, a vice-president at Fairchild Camera and Instrument Corporation, was appointed president of Amdahl Corporation. Effecting changes that helped save the company, White laid off almost half the employees and concentrated on marketing efforts and field support services. He was also instrumental in negotiations with Fujitsu and Heizer to get the funding necessary to complete the company's first product.

In June 1975 Amdahl shipped its first computer, the Amdahl 470 V/6, to NASA's Goddard Spaceflight Center in New York. The computer competed directly with IBM's System 370 Model 168. The initial sale was followed by sales to the University of Michigan, Texas A & M University, and the University of Alberta. Massachusetts Mutual Life, Amdahl's first commercial customer, chose Amdahl's 470 V/6 over the IBM 370 when IBM raised its prices and delayed delivery. Other customers followed, including AT & T.

Determined to best IBM, Amdahl was the first truly plug-compatible manufacturer, or manufacturer whose products were compatible with both IBM hardware and software. Critics maintained that the Amdahl machines provided better performance for less money. IBM's machines were water-cooled, while Amdahl's were air-cooled, which decreased installation costs by $50,000 to $250,000. The use of LSI (large-scale-integration), many integrated circuits on each chip, meant the Amdahl 470 V/6 was one-third the size of IBM's 360/168; the V/6 also performed more than twice as fast and sold for about 10 percent less. Machine sales remained slow because of concerns over the company's survival, but by the spring of 1977 Amdahl had 50 units in place, seriously challenging IBM in large-scale computer placements. To improve its cash position, Amdahl decided to sell rather than lease its equipment. IBM responded by slashing prices, forcing Amdahl to follow suit.

In 1976 Amdahl successfully went public with its stock. With the new funds, the company converted its debt to equity, created substantial cash reserves, and found itself operating at a profit. Revenues climbed from less than $14 million in 1975 to $321 million in 1977, with net income of $48.2 million.

In response to the challenge from Amdahl, IBM announced several machine enhancements. Not until the announcement of its 3033 in 1977, however, did IBM come up with a competitor for the price/performance ratio of Amdahl's 470 V/6. Amdahl responded by announcing a new computer: the 470 V/7. About one-and-a-half times faster than IBM's 3033, it would cost only 3 percent more. A year later Amdahl had installed 100 of the machines.

Amdahl's loosely organized corporate structure was very unusual for such a high-revenue organization. Even after two years of full operation, Gene Amdahl and Gene White still spent much of their time in high-level sales--in fact, many customers insisted on meeting Amdahl personally before closing the deal. Any mention of a chief executive officer was intentionally omitted from the corporate bylaws, but in 1977 Amdahl did hire John C. Lewis as president. Lewis had previously served as president of the business systems and data systems divisions of Xerox Corporation, and had spent ten years in management at IBM. Gene White became deputy chairman.

In early 1979, IBM introduced a line of medium-sized computers called the 4300 series. This line, coupled with reports that IBM would soon be announcing the H-Series of large computers, prompted many Amdahl customers to lease rather than buy equipment in order to be able to shift to an IBM product later. This development created serious cash flow problems at Amdahl. Revenues dropped by $21 million in 1979, with a 64 percent drop in net income.

On September 1, 1979, Gene Amdahl resigned as chairman, a post he had held since 1970. Deputy Chairman Eugene R. White became chairman of the board and CEO, a post that had never before been filled. Staying on the board as chairman emeritus, Amdahl led a new technical excellence committee and focused on strategic development. Less than a year later he resigned from the board to form Trilogy Corporation, a computer company that would compete directly with Amdahl and IBM. Recognized as one of the world's leading innovators in computer design, Amdahl again put his creativity to work on a new venture.

In 1979 and 1980 Amdahl Corporation failed in two attempted mergers, first with Memorex Corporation, a manufacturer of computer data-storage equipment, and then with Storage Technology Corporation, a maker of printers and tape and disc storage subsystems. The failures were attributed to Fujitsu, Amdahl's largest shareholder with a 34 percent holding, which feared losing its influence in a merger and sought to keep tight reins on proprietary technology. Fujitsu's demands were rejected by the merger partners.

In November 1980, IBM announced the 3081 processor, previously labeled the H-Series, which would offer twice the performance of IBM's top model, the 3033, upon its completion in late 1981. The industry waited for Amdahl's response. Six days later Gene White announced the 580 series, a computer with processors twice as powerful as the Amdahl 470 series and still compatible with it, which also featured a more compact body and greater energy efficiency. Amdahl's new product was not slated for shipment until April 1982, however, and did not actually ship until August 1982, causing a drop in net income. In addition, Amdahl's early 580 series processor had significant reliability problems and was lacking in some of the features of the new IBM product. Amdahl's competitive advantage was further eroded by a U.S. Justice Department decision to dismiss a 13-year-old antitrust suit against IBM, enabling the giant computer manufacturer to price its products more aggressively and move faster with new technologies.

To expand its market, in 1980 Amdahl completed the successful acquisition of Tran Telecommunications Corporation, a maker of digital data communication networks. In 1982 Amdahl branched into storage devices by offering a direct-access storage device supplied by Fujitsu. This enabled Amdahl to broaden its product base and provided a buffer against the vicissitudes of direct competition with IBM's large-scale computers. By 1988 Amdahl's sales of storage devices had grown to about 20 percent of total sales. To remain competitive in its fierce battle with IBM, Amdahl was spending 13 percent of total sales on research and development in 1983, while IBM spent only 6.3 percent.

In 1984 Amdahl developed UTS, its version of UNIX, the operating system developed by AT & T. Amdahl claimed that UTS, which was compatible with UNIX, operated 25 percent faster run on the Amdahl 580 than on IBM's product, and did so for a lower licensing fee. The developers of the operating system ensured its complete compatibility with IBM's control programs.

Amdahl introduced multiple domain feature (MDF) in late 1984. MDF enabled a computer to run two or more different operating systems concurrently, while also performing multiple tasks. In just over two years, 30 percent of the Amdahl 580 series sites used this feature, cutting costs on software, hardware, and personnel.

In 1984 Heizer decided to liquidate its Amdahl stock. Fujitsu bought the offering, expanding its holdings to about 49 percent. The Japanese firm was prohibited by mutual agreement from owning more than 49.5 percent of Amdahl's shares, and in 1990 Fujitsu held about 43 percent of the company's stock.

Over the years Fujitsu provided important components and subassemblies for Amdahl processors, including LSI logic chips and very large-scale integration emitter-coupled logic chips, which were essential to Amdahl products. Fujitsu also played an important role in the design and manufacture of peripheral products. The two companies worked closely in supporting each other in their respective technological developments.

In May 1985 a former IBM executive, E. Joseph Zemke, joined Amdahl as COO, sharing the office of the president with President and CEO John C. Lewis. Zemke had most recently been president and CEO of Auto-Trol Technology of Denver, Colorado, and had been corporate director of marketing at IBM.

Amdahl's model 5890, introduced in October 1985 to compete directly with IBM's Sierra-class CPU, stood up against its IBM counterpart in reliability and technology and offered multiprocessor capabilities that enhanced the performance range of Amdahl processors. In late 1986, Amdahl began shipping its new model. The computers performed even better than advertised, and final quarter sales boosted revenues to nearly $1 billion. The success of the model 5890 was reflected in Amdahl's increased customer base. Between 1980 and 1985 its customer sites in the United States grew from 450 to 1,350, and it expanded internationally from 14 to 19 countries. The company also increased sales of its large-scale disc-storage products made by Fujitsu.

Continued shipment of its successful product lines during 1987 catapulted Amdahl's revenues to $1.5 billion, an increase of almost 56 percent over the previous year, and earnings jumped nearly 250 percent. The company upgraded its successful 5890 to keep abreast of improvements in IBM's 3090 computer. Its further commitment to UTS enhanced its strength.

John C. Lewis was elected chairman of Amdahl in May 1987, retaining the title of CEO. Joseph Zemke became president, but continued his duties as COO. Gene White, formerly chairman, again became vice-chairman.

For most of its existence, Amdahl had played catch-up to IBM's product announcements, but in May 1988, it took the initiative and announced a new product line, the 5990 processor. Orders poured in. IBM reacted quickly to defend its 69 percent of the U.S. large-scale computer market share, but the new processor--acknowledged as the fastest in the industry--not only outperformed IBM by almost 50 percent, but was also more compact and less costly. By the end of 1988, Amdahl had shipped more than 40 of its new mainframes. The price and performance features of Amdahl's products raised sales nearly 17 percent to $2.1 billion. IBM responded by discounting its systems. Amdahl announced its own discounts, and the decreased profit margin caused earnings to fall by 30 percent in 1989.

Amdahl's consistent ability to produce computers with a superior price/performance ratio helped keep the company competitive in a market dominated by IBM. Staying on the leading edge of technology and catering to its customers' needs launched Amdahl to more than $2 billion in revenues in 1989. In February, Amdahl acquired Key Computer Laboratories, Inc., a company specializing in scalar computing that was expanding globally, with 33 percent of its revenues coming from Europe and 8 percent from Asia and the Pacific region in 1989. In 1991 Amdahl introduced Huron, a successful new application development software, and established the Canadian Software Development Centre. The center was run by Huron's creator, Helge Knudsen.

As the 1990s progressed, the major threat to Amdahl's viability no longer appeared to be IBM, but the shrinking mainframe computer market. As smaller, cheaper, and more powerful machines became available, Amdahl found its sales slipping. Excessive costs forced the company to stop work on a mainframe Unix product that had long been underway. By September 1993, sales had collapsed. Amdahl's Zemke (who became CEO in 1992) was quoted in Business Week as saying, 'It was like Death Valley.' Amdahl shut down factory lines and cut back the workforce three times that year. The company reported a net loss of more than $575 million for 1993 and revenues fell to $1.68 billion, a 33 percent drop from the record revenues of $2.52 billion the previous year.

Analysts predicted that Amdahl's continued success would require stronger innovation. Amdahl's strategy was to offer its customers integrated packages combining its hardware technology with the industry's most advanced software, as well as stellar support and consulting services. Amdahl's maintenance, support, and consulting services made up 28 percent of revenues in 1993 and increased another 11 percent in the first quarter of 1994. Margins on those services were almost double the hardware margins, and Amdahl's service businesses were consistently given the highest ratings in the industry.

In the following year, Amdahl entered into new partnerships with three computer firms: Electronic Data Systems, nCube, and Sun Microsystems. The agreement with Electronic Data Systems spawned the Antares Alliance Group, a joint software development group 80 percent owned by Amdahl. Antares was formed to market Amdahl's Huron and research new software ideas and prototypes for business analysis and modeling programs. Helge Knudsen became director of the Antares Research Institute.

In 1994 Amdahl introduced the Xplorer 2000 series. The new product was the result of an alliance between Amdahl, Oracle, and Information Builders, Inc. The partnership was formed, according to Software Magazine, to explore opportunities to create 'massively parallel database servers and software that will let customers process thousands of transactions per second and share data between MVS and Unix systems.'

Later that year, Amdahl and Sun Microsystems introduced A+ Edition, a group of extensions that allowed Sun's symmetrical multiprocessing servers to perform more efficiently when a higher number of total possible servers were working. The software accomplished this by providing tuning for database applications with a large number of users and more evenly distributing the workload among the processors in the servers. While the new product was well received, some potential customers expressed concern about the cost for the value.

Expanding on its position as a provider of integrated services, Amdahl won a bidding war for DMR Group Inc., acquiring the Canadian firm in November 1995 for about $140 million. DMR provided information technology consulting services as well as systems development, systems integration, and outsourcing services on a worldwide basis. The firm had annual revenues of nearly $220 million, which boosted the share of Amdahl revenue that came from software and services to 40 percent. DMR was combined with Amdahl's Business Solutions Group to form DMR Consulting Group, Inc., which operated as a subsidiary.

Zemke resigned as CEO in March 1996 for 'personal reasons.' The move came in the wake of rather dismal results for 1995: net income of only $28.5 million and a further decline in revenues to $1.52 billion. Lewis became CEO once again. Soon thereafter, Amdahl acquired another services-oriented company, Trecom Business Systems Inc., for $145 million. Based in Edison, New Jersey, Trecom focused mainly on designing and providing client-server networks for corporations. Its geographic presence in the eastern and southern United States meshed well with DMR's strength in the West and in Canada. The firm had annual revenues of $140 million. Trecom was eventually merged into DMR.

Amdahl returned to the red for 1996, reporting a $326 million net loss on revenues of $1.63 billion, partly due to costs related to the integration of its acquisitions. An even larger factor was a $130 million writeoff of outmoded water-cooled mainframe inventory. Amdahl's mainframes were hurt by IBM's 1995 introduction of CMOS-based mainframes, which were air-cooled and less costly to operate. Amdahl had to play catch-up in introducing its own CMOS-based models, the Millennium Global Servers, in late 1996. The later months of 1996 also saw Amdahl begin selling a line of Windows NT-based servers called EnVista. Amdahl packaged the servers with software and services related to the Internet, intracompany communications and data sharing, and database applications. In the area of open systems, the company added new storage systems to its product line and began reselling Sun Microsystems' SPARC servers. Meantime, nearly two-thirds of revenues for 1996 were generated by Amdahl's software and services operations.

By mid-1997, with Amdahl having posted six straight quarterly losses, there was much skepticism about the future viability of the company. Those concerns were laid to rest in September of that year when Fujitsu purchased the 58 percent of Amdahl it did not already own for $878 million. Amdahl was now a wholly owned subsidiary of Fujitsu and could tap into the very deep pockets of the Japanese electronics giant. In the immediate wake of the buyout, David B. Wright was named to succeed Lewis as CEO. Wright had been executive vice-president of the company's hardware and systems support operations, and his background in services was a key factor in his selection as Amdahl continued to increase its emphasis on software, services, and consulting. DMR in particular was growing at the rapid rate of 30 percent per year and its revenues reached $700 million in 1997. Part of this surge came from the accelerating demand for services related to the fixing or replacement of systems affected by the year 2000 computer bug.

In early 1998 Amdahl entered into an alliance with Microsoft Corporation to provide products and services designed to integrate Microsoft's Windows NT and BackOffice products with mainframe systems. The following year the company acquired Sentryl Software, which developed software for automated storage management systems.

In October 2000 Wright resigned as CEO, with Yasushi Tajiri named interim CEO. Just a few weeks later, the company announced that it was exiting from its founding mainframe business. On the hardware side, Amdahl would now be involved only in the server and storage sectors. The company's future, in any event, clearly lay in the world of services and consulting. In December 2000 Amdahl announced that it would eliminate nearly one-fifth of its California workforce in connection with its exit from mainframes. At the same time, Fujitsu turned Amdahl into a holding company for several businesses: Amdahl Software; DMR Consulting; Amdahl IT Services, which focused on information technology infrastructure services for large-scale enterprises; and Fujitsu Technology Solutions, which was the company's hardware arm, selling servers and storage systems. In March 2001 Amdahl Software was relaunched as Fujitsu Software Technology Corporation (Fujitsu Softek), with a mission of providing comprehensive software solutions in various areas of data storage. These moves early in the new millennium continued Amdahl's transformation from mainframe manufacturer to provider of information technology software, services, and consulting.

Amdahl Corporation is an information technology company which specializes in IBM mainframe-compatible computer products. Founded in 1970 by Dr. Gene Amdahl, a former IBM employee, it has been a wholly owned subsidiary of Fujitsu since 1997. The company is located in Sunnyvale, California.

Amdahl was a major supplier of large mainframe computers, and later of UNIX and Open systems software and servers, data storage subsystems, data communications products, application development software, and a variety of educational and consulting services. In the 1970s, when IBM had come to dominate the mainframe industry, Amdahl created plug-compatible machines that could be used with the same hardware and software as offerings from IBM, but were more cost-effective. These machines gave "Big Blue" some of the little competition it had in that very high-margin computer market segment. Proverbially, during this time savvy IBM customers liked to have Amdahl coffee mugs visible in their offices when IBM salespeople came to visit. While winning about 8% of the mainframe business worldwide, Amdahl won a position of market leader in some regions, most notably Charlotte, North Carolina. In the early to mid-1990s, Amdahl won most of the major contracts for mainframes in the Carolinas.

Amdahl Corp. launched its first product, the Amdahl 470/6, in 1975, competing directly against IBM's high-end machines in the then-current System/370 family, but with IBM's announcement of Dynamic Address Translation (DAT), Amdahl announced the 470V/6 and dropped the 470/6. (At IBM, Gene Amdahl had co-designed the groundbreaking 32-bit architecture, 24-bit addressing, System/360 line of computers. Applications written for the System/360 can still run, unmodified, on today's zSeries mainframes four decades later.) At the time of its introduction, the 470V/6 was less expensive but still faster than IBM's comparable offerings. The first two 470V/6 machines were delivered to NASA (Serial Number 00001) and the University of Michigan (Serial Number 00002). For the next quarter century Amdahl and IBM competed aggressively against one another in the high-end server market, with Amdahl grabbing as much as 24% marketshare. Amdahl owed some of its success to antitrust settlements between IBM and the U.S. Department of Justice, which ensured that Amdahl's customers could license IBM's mainframe software under reasonable terms.

Dr Gene Amdahl was committed to expanding the capabilities of the uniprocessor mainframe during the late 1970s and early 1980s. Amdahl engineers, working with Fujitsu circuit designers, developed unique air-cooled chip designs using high speed ECL (emitter-coupled logic) circuit macros packaged in a chip with a heat-dissipating cooling attachment (looked like the heat-dissipating fins on a motorcycle engine) mounted directly to the top of the chip. This patented technology allowed the Amdahl mainframes of this era, unlike IBM systems, to be completely air-cooled, and did not require "plumbing" for chilled water.

In the 470 systems, the chips were mounted in a 6x7 array on multi-layer cards, which were then mounted in vertical columns. The cards had eight connectors that attached the micro-coaxial cables that interconnected the system components. A conventional backplane was not used in the central processing units. The card columns held at least three cards per side. Each column had 3 large fans to move the considerable amount of air needed to cool the chips.

In the 580 systems, the chips were mounted in an 11-by-11 array on multi-layer boards called Multi-Chip Carriers (MCCs), that were positioned in high airflow for cooling. The MCCs were mounted horizontally in a large rectangular frame. The MCCs slid into a complex physical connection system and the processor "side panels" interconnected the system, providing clock propagation delays that maintained race-free synchronous operation at relatively high clock speeds (15–18 ns base clock cycles). This processor box was cooled with high speed fans generating horizontal air flow across the MCCs.

Additional models of Amdahl uniprocessor systems included the 470V/5, /7 and /8 systems. The 470V/8, first shipped in 1980, incorporated high speed 64K cache buffers to improve performance, and the first real hardware based virtualization known as "Multiple Domain Facility").

Amdahl also pioneered a variable speed feature on the V5 and V7 systems that allowed the customer to run the CPUs at a higher performance level when necessary. The customer was charged by the number of hours used. Some at Amdahl thought this feature would anger customers, but it became quite popular as management could now control expenses while still having "afterburner" speed available when necessary.

Always the entrepreneur, Gene Amdahl left the company he founded in 1980, moving on to start a couple of new technology companies.

With Gene Amdahl's departure, and increasing influence from Fujitsu, Amdahl broke into large system multi-processor design in the mid-80's with the 5870 (attached processor) and 5880 (full multiprocessor) models.

Amdahl under the leadership of Tom O'Rourke attempted to enter the IBM Peripherals business in Front End Processors and Storage Products. Resistance by factions within Amdahl which opposed any broadening of the business, sabotaged these businesses. Initial efforts in Peripheral Produces were very successful. Jack Lewis, former CEO of Amdahl was a great supporter of these efforts, however, factions, fighting for limited resources, limited investment in these critical peripheral businesses. Reliance upon a single product, within the complex business of mainframes and their equally valuable peripherals, doomed the company when market forces shifted to Intel based processors.

Market exit

Amdahl Corporation enjoyed perhaps its best sales during IBM's transition to CMOS technology in the early to mid 1990s. At first IBM's new mainframe CMOS processors, the IBM 9672 G3 and G4, could not perform as well as spare-no-expense bipolar technology, giving Amdahl a temporary advantage. However, IBM's CMOS strategy paid off in the long run, allowing IBM's Poughkeepsie factory to produce even faster mainframes at lower cost as the technology matured. By the time IBM introduced its breakthrough 64-bit zSeries 900 in 2000, it was all over for Amdahl's hardware business, which only had 31-bit-addressing Millennium and OmniFlex servers to sell. In late 2000, Fujitsu/Amdahl announced that the company had no plans to invest the estimated US $1 billion (or more) to create an IBM-compatible 64-bit system.

Historically it is unclear whether Fujitsu/Amdahl made the right decision. Despite heavy competition from other server platforms, IBM's zSeries has enjoyed a resurgence due to the widespread adoption of Linux and the escalating transaction volumes (in CICS, IMS, DB2, and other mainframe subsystems) brought about by e-business growth. IBM's zSeries revenues are actually increasing despite declining prices. As of late 2005 IBM is the only manufacturer of production-grade IBM-compatible mainframes. However, Fujitsu announced in late 2005 that EDS would sell its line of "mainframes" outside Japan. Unlike prior models, these Fujitsu systems are not compatible with IBM's and cannot run z/OS, but the announcement has customers wondering if Fujitsu will take the next step in re-entering the (now growing) market. Amdahl also failed in its effort to introduce ObjectStar software (initially known as Huron) during this period and that product later became a successful management buy out(MBO). Objectstar was later on acquired by integration software vendor TIBCO in 2005.

Amdahl customer options

z/OS 1.5 is the last release of IBM's flagship operating system still able to run on 31-bit mainframes, including Amdahl and older IBM systems. IBM effectively ended support for z/OS 1.5 on March 29, 2007.^[1] In May, 2006, IBM announced that the next version of z/VSE, Version 4, would require a 64-bit system, signaling the end to 31-bit support for that operating system. z/TPF, which became available in December, 2005, also requires a 64-bit system. The 31-bit Linux distributions will survive as long as the open source community and distributors have interest. So while there's still some potential life for Amdahl's hardware, the transition to 64-bit systems is essentially complete. Some companies and governments still had Amdahl systems performing useful work into mid-2006, and Fujitsu/Amdahl promised support to those customers with replacement parts and other services through March 31, 2009.

Arguably IBM did not have a suitable replacement model for many Amdahl customers until the May, 2004, introduction of the zSeries 890. The previous zSeries 800 also became an attractive replacement for Amdahl machines by late 2005 as that model's typical used price fell below $100,000 and continued to fall. The System z9 BC model, introduced in May, 2006, increased IBM's attractiveness yet again, and the BC drove z800 and z890 prices down even more. The late 2008 introduction of the IBM System z10 BC yet again made IBM's equipment more enticing. In fact, Fujitsu/Amdahl now sells used IBM mainframes and offers services to migrate customers to the IBM machines. (This migration is straightforward and comparable to upgrading from one IBM model to a newer IBM model.) Other, generally less attractive options include running without support, rewriting applications, or possibly running applications under FLEX-ES. FLEX-ES is a mainframe instruction set emulator that supports ESA/390 and, in some cases, z/Architecture operating systems and software.

The vestiges of Amdahl's ESA/390 emulation project were resurrected under a new name: Platform Solutions Inc. Using capital from Intel, Hewlett-Packard, Microsoft, and other major investors they designed a line of Itanium-based computers and software to emulate z/Architecture machines so that they could run zSeries operating systems, with zSeries channels for attaching real IBM equipment as well as virtual simulators for most hardware to minimize the need for IBM’s peripheral equipment. Its LPARs hosted not only IBM operating systems but 64-bit Intel Itanium Linux, HP-UX, Solaris, and potentially other operating systems.

Platform Solutions started shipping its machines in the first quarter of 2007. This action precipitated a lawsuit from IBM, citing patent infringement and PSI's failure to negotiate a z/Architecture license, and IBM refused to license its operating systems and software on PSI's machines. Platform Solutions countered that by “tying” the sale of its software to the sale of its hardware, IBM was in violation of its prior anti-trust agreement with the U.S. Justice Dept. In July, 2008, IBM acquired PSI, and both companies dropped their lawsuits against each other.^[2] PSI's machines are no longer available.

Fujitsu continues to sell its "GlobalServer" (GS21) mainframe models in the Japanese domestic market. The GS21 machines are essentially ESA/390 (31-bit) instruction set processors largely based on Amdahl-designed technologies but are only compatible with Fujitsu's domestic market operating systems: OSIV/MSP-EX and OSIV/XSP. MSP is most similar to classic IBM MVS/ESA, and XSP is most similar to classic IBM VSE/ESA. Fujitsu GS21 mainframe hardware would most closely correspond to late 1990s IBM G5 or G6 mainframes in terms of their instruction set support. Fujitsu has stated the company has no intention to license or implement Z/Architecture (64-bit). Hitachi continues to operate its domestic Japanese mainframe business in similar fashion.
