Background and origins: World War II–1957

s. A number of these were produced by a team dedicated to the task working in the Washington, D.C., area. With the post-war wind-down of military spending, the Navy grew increasingly worried that this team would break up and scatter into various companies, and it started looking for ways to keep the code-breaking team together. Eventually they found their solution: John Parker, the owner of a Chase Aircraft affiliate named Northwestern Aeronautical Corporation located in

, was about to lose all his contracts due to the ending of the war. The Navy never told Parker exactly what the team did, since it would have taken too long to get top secret clearance. Instead they simply said the team was important, and they would be very happy if he hired them all. Parker was obviously wary, but after several meetings with increasingly high-ranking Naval officers it became apparent that whatever it was, they were serious, and he eventually agreed to give this team a home in his military glider factory. The result was Engineering Research Associates (ERA). Formed in 1946, this contract engineering company worked on a number of seemingly unrelated projects in the early 1950s. Among these was the ERA Atlas, an early military stored program computer, the basis of the Univac 1101, which was followed by the 1102, and then the 36- bit ERA 1103 ( UNIVAC 1103). The Atlas was built for the Navy, which intended to use it in their non-secret code-breaking centers. In the early 1950s a minor political debate broke out in

about the Navy essentially "owning" ERA, and the ensuing debates and legal wrangling left the company drained of both capital and spirit. In 1952, Parker sold ERA to Remington Rand. Although Rand kept the ERA team together and developing new products, it was most interested in ERA's magnetic drum memory systems. Rand soon merged with Sperry Corporation to become Sperry Rand. In the process of merging the companies, the ERA division was folded into Sperry's UNIVAC division. At first this did not cause too many changes at ERA, since the company was used primarily to provide engineering talent to support a variety of projects. However, one major project was moved from UNIVAC to ERA, the UNIVAC II project, which led to lengthy delays and upsets to nearly everyone involved. Since the Sperry "big company" mentality encroached on the decision-making powers of the ERA employees, a number left Sperry to form the Control Data Corp. in Sept 1957,Control Data Corporation was incorporated in Minnesota, July 8, 1957 setting up shop in an old warehouse across the river from Sperry's St. Paul laboratory, in

Early designs and Cray's big plan

CDC started business by selling subsystems, mostly drum memory systems, to other companies. Cray joined the next year, and he immediately built a small

s. The 160A was particularly notable as it was built as a standard office desk, which was unusual packaging for that era. New versions of the basic 1604 architecture were rebuilt into the CDC 3000 series, which sold through the early and mid-1960s. Cray immediately turned to the design of a machine that would be the fastest (or in the terminology of the day, largest) machine in the world, setting the goal at 50 times the speed of the 1604. This required radical changes in design, and as the project "dragged on" — it had gone on for about four years by then — the management got increasingly upset and it demanded greater oversight. Cray in turn demanded (in 1962) to have his own remote lab, saying that otherwise, he would quit. Norris agreed, and Cray and his team moved to Cray's home town, Chippewa Falls, Wisconsin. Not even Bill Norris, the founder and president of CDC, could visit Cray's laboratory without an invitation.


Peripherals business

In the early 1960s, the corporation moved to the Highland Park neighborhood of St. Paul where Norris lived. Through this period, Norris became increasingly worried that CDC had to develop a "critical mass" to compete with IBM. To do this, he started an aggressive program of buying up various companies to round out CDC's peripheral lineup. In general, they tried to offer a product to compete with any of IBM's, but running 10% faster and costing 10% less. This was not always easy to achieve. One of its first peripherals was a tape transport, which led to some internal wrangling as the Peripherals Equipment Division attempted to find a reasonable way to charge other divisions of the company for supplying the devices. If the division simply "gave" them away at cost as part of a system purchase, they would never have a real budget of their own. Instead, a plan was established in which it would share profits with the divisions selling its peripherals, a plan eventually used throughout the company. The tape transport was followed by the ''405 Card Reader'' and the ''415 Card Punch'', followed by a series of

Train printers and band printers in Rochester were developed in a joint venture with NCR and ICL, with CDC holding controlling interest. This joint venture was known as Computer Peripherals, Inc.

Norris was particularly interested in breaking out of the punched card–based workflow, where IBM held a stranglehold. He eventually decided to buy

(OCR) systems. The idea was to bypass the entire punched card stage by having the operators simply type onto normal paper pages with an OCR-friendly typewriter font, and then submit those pages to the computer. Since a typewritten page contains much more information than a punched card (which has essentially one line of text from a page), this would offer savings all around. This seemingly simple task turned out to be much harder than anyone expected, and while CDC became a major player in the early days of OCR systems, OCR has remained a niche product to this day. Rabinow's plant in Rockville, MD was closed in 1976, and CDC left the business. With the continued delays on the OCR project, it became clear that punched cards were not going to go away any time soon, and CDC had to address this as quickly as possible. Although the 405 remained in production, it was an expensive machine to build. So another purchase was made,

This was never very profitable, and in 1965, several managers suggested that the unprofitable centers be closed in a cost-cutting measure. Nevertheless, Norris was so convinced of the idea that he refused to accept this, and ordered an across-the-board "belt tightening" instead.

CDC 6600: defining supercomputing

Meanwhile, at the new Chippewa Falls lab, Seymour Cray, Jim Thornton, and Dean Roush put together a team of 34 engineers, which continued work on the new computer design. One of the ways they hoped to improve the CDC 1604 was to use better transistors, and Cray used the new silicon transistors using the planar process, developed by

The speed of light restriction forced a more compact design with refrigeration designed by Dean Roush. In 1964, the resulting computer was released onto the market as the CDC 6600, out-performing everything on the market by roughly ten times. When it sold over 100 units at $8 million ($ million in dollars) each; it was considered a

line of computers. The engineers were directed to make it 360-compatible, but that compromised its performance. The ACS was canceled in 1969, without ever being produced for customers. Many of the engineers left the company, leading to a brain-drain in IBM's high-performance departments. In the meantime, IBM announced a new System/360 model, the Model 92, which would be just as fast as CDC's 6600. Although this machine did not exist, sales of the 6600 dropped drastically while people waited for the release of the mythical Model 92. Norris did not take this tactic, dubbed as

lawsuit launched against IBM a year later, he eventually won a settlement valued at $80 million. As part of the settlement, he picked up IBM's subsidiary, Service Bureau Corporation (SBC), which ran computer processing for other corporations on its own computers. SBC fitted nicely into CDC's existing service bureau offerings. During the designing of the 6600, CDC had set up ''Project SPIN'' to supply the system with a high speed

SPIN explored all of these approaches, and eventually delivered a 28" diameter fixed disk and a smaller multi-platter 14" removable disk-pack system. Over time, the hard disk business pioneered in SPIN became a major product line.


CDC 7600 and 8600

In the same month it won its lawsuit against IBM, CDC announced its new computer, the CDC 7600 (previously referred to as the 6800 within CDC). This machine's hardware clock speed was almost four times that of the 6600 (36 MHz vs. 10 MHz), with a 27.5 ns clock cycle, and it offered considerably more than four times the total throughput, with much of the speed increase coming from extensive use of pipelining. The 7600 did not sell well because it was introduced during the 1969 downturn in the U.S. national economy. Its complexity had led to poor reliability. The machine was not totally compatible with the 6000-series and required a completely different operating system, which like most new OSs, was primitive. The 7600 project paid for itself, but damaged CDC's reputation. The 7600 memory had a split primary- and secondary-memory which required user management but was more than fast enough to make it the fastest uniprocessor from 1969 to 1976. A few dozen 7600s were the computers of choice at supercomputer centers around the world. Cray then turned to the design of the CDC 8600. This design included four 7600-like processors in a single, smaller case. The smaller size and shorter signal paths allowed the 8600 to run at much higher clock speeds which, together with faster memory, provided most of the performance gains. The 8600, however, belonged to the "old school" in terms of its physical construction, and it used individual components soldered to circuit boards. The design was so compact that cooling the CPU modules proved effectively impossible, and access for maintenance difficult. An abundance of hot-running solder joints ensured that the machines did not work reliably; Cray recognized that a re-design was needed.


The STAR and the Cyber

In addition to the redesign of the 8600, CDC had another project called the CDC STAR-100 under way, led by Cray's former collaborator on the 6600/7600, Jim Thornton. Unlike the 8600's "four computers in one box" solution to the speed problem, the STAR was a new design using a unit that we know today as the
vector processor In computing, a vector processor or array processor is a central processing unit (CPU) that implements an instruction set where its instructions are designed to operate efficiently and effectively on large one-dimensional arrays of data calle ...
. By highly pipelining mathematical instructions with purpose-built instructions and hardware, mathematical processing is dramatically improved in a machine that was otherwise slower than a 7600. Although the particular set of problems it would be best at solving was limited compared to the general-purpose 7600, it was for solving exactly these problems that customers would buy CDC machines. Since these two projects competed for limited funds during the late 1960s, Norris felt that the company could not support simultaneous development of the STAR and a complete redesign of the 8600. Therefore, Cray left CDC to form the

company in 1972. Norris remained, however, a staunch supporter of Cray, and invested money into Cray's new company. In 1974 CDC released the STAR, designated as the Cyber 203. It turned out to have "real world" performance that was considerably worse than expected. STAR's chief designer, Jim Thornton, then left CDC to form the Network Systems Corporation. In 1975, a STAR-100 was placed into service in a Control Data service center which was considered the first supercomputer in a data center. Founder William C. Norris presided at the podium for the press conference announcing the new service. Publicity was a key factor in making the announcement a success by coordinating the event with Guinness; thus, establishing the Star-100 as "The most powerful and fastest computer" which was published in the Guinness Book of World Records. The late Duane Andrews, Public Relations, was responsible for coordinating this event. Andrews successfully attracted many influential editors including the research editor at Business Week who chronicled this publicity release "... as the most exciting public event he attended in 20 years". Sharing the podium were William C. Norris, Boyd Jones V.P. and S. Steve Adkins, Data Center Manager. It was extremely rare for Bill Norris to take the podium being a very private individual. Also, during the lunch at a local country club, Norris signed a huge stack of certificates attesting to the record which were printed by the Star 100 on printer paper produced in our Lincoln, Nebraska plant. The paper included a half-tone photo of the Star 100. The main customers of the STAR-100 data center were oil companies running oil reservoir simulations. Most notably was the simulation controlled from a terminal in Texas which solved oil extraction simulations for oil fields in Kuwait. A front page Wall Street Journal news article resulted in acquiring a new user, Allis-Chalmers, for simulation of a damaged hydroelectric turbine in a Norwegian mountain hydropower plant. A variety of systems based on the basic 6600/7600 architecture were repackaged in different price/performance categories of the

, were using the same basic design techniques as the STAR, but were computing much faster. The Star 100 was able to process vectors up to 64K (65536) elements, versus 64 elements for the Cray-1, but the Star 100 took much longer for initiating the operation so the Cray-1 outperformed with short vectors. Sales of the STAR were weak, but Control Data Corp. produced a successor system, the Cyber 200/205, that gave Cray Research some competition. CDC also embarked on a number of special projects for its clients, who produced an even smaller number of black project computers. The CDC Advanced Flexible Processor (AFP), also known as CYBER PLUS, was one such machine. Another design direction was the "Cyber 80" project, which was aimed at release in 1980. This machine could run old 6600-style programs, and also had a completely new 64-bit architecture. The concept behind Cyber 80 was that current 6000-series users would migrate to these machines with relative ease. The design and debugging of these machines went on past 1980, and the machines were eventually released under other names. CDC was also attempting to diversify its revenue from hardware into services and this included its promotion of the PLATO computer-aided learning system, which ran on Cyber hardware and incorporated many early computer interface innovations including bit-mapped touchscreen terminals.

Meanwhile, several very large Japanese manufacturing firms were entering the market.

Commercial Credit Corporation

In 1968, Commercial Credit Corporation was the target of a hostile takeover by Loews Inc. Loews had acquired nearly 10% of CCC, which it intended to break up on acquisition. To avoid the takeover, CCC forged a deal with CDC lending them the money to purchase control in CCC instead, and "That is how a computer company came to own a fleet of fishing boats in the Chesapeake Bay." By the 1980s, Control Data entered an unstable period, which resulted in the company liquidating many of their assets. In 1986,

chips, which produced much less heat. The effort ended after half-hearted attempts to sell ETA Systems. In 1989, most of the employees of ETA Systems were laid off, and the remaining ones were folded into CDC. Despite having valuable technology, CDC still suffered huge losses in 1985 ($567 million) and 1986 while attempting to reorganize. As a result, in 1987 it sold its PathLab Laboratory Information System to 3M. While CDC was still making computers, it was decided that hardware manufacturing was no longer as profitable as it used to be, and so in 1988 it was decided to leave the industry, bit by bit. The first division to go was Imprimis. After that CDC sold other assets such as VTC (a chip maker that specialized in mass-storage circuitry and was closely linked with MPI), and non-computer-related assets like Ticketron. Finally, in 1992, the computer hardware and service businesses were spun out as Control Data Systems, Inc. (CDS). In 1999, CDS was bought out by
