History of Norsk Data

History of Norsk Data is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand History of Norsk Data rather than just read about it. In short: Norsk Data (ND) was a Norwegian manufacturer of minicomputers which operated between 1967 and 1992. The company was established as A/S Nordata – Norsk Data-Elektronikk on 7 July 1967 and took into use the Norsk Data brand in 1975.

Key takeaways

  • History of Norsk Data belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect History of Norsk Data to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of History of Norsk Data from memory before moving on to harder problems.

Reference excerpt

Norsk Data (ND) was a Norwegian manufacturer of minicomputers which operated between 1967 and 1992. The company was established as A/S Nordata – Norsk Data-Elektronikk on 7 July 1967 and took into use the Norsk Data brand in 1975. The company was founded by Lars Monrad-Krohn, Rolf Skår and Per Bjørge, three computer engineers working at the Norwegian Defence Research Establishment which had just built the minicomputer SAM 2. ND's first contract was the delivery of a Nord-1 computer to Norcontrol. Initially in competition with Kongsberg, ND started delivering computers to Norwegian institutions. By 1972 the company had developed Sintran operating system, the 32-bit Nord-5 and a time sharing system. The international break-through came with the 1973 delivery of computers to CERN and the company soon had half their sales abroad. Two years later the database program SIBAS had been completely ported and made available, and the following year a 150-terminal system connected via X.21/X.25 based XMSG and a flight simulator backbone for the F-16 were delivered. In 1978 Norsk Data both bought Tandberg and launched its office suite Notis, although Tandberg was sold again in 1980. ND became the first foreign-listed Norwegian company in 1981, which also saw the launch of the 32-bit ND-500. Throughout the 1980s ND acquired a series of domestic and foreign hardware and software companies, many loosely oriented at increased hardware sales. At the peak in 1986 and 1987, Norsk Data had 4,500 employees, 2.5 billion Norwegian krone (NOK) in revenue and was Norway's second-largest company by market capitalization—having increased fifty-fold between 1977 and 1985. Despite late attempts to develop Ndix, ND never succeeded at entering the Unix market which started to dominate in the late 1980s. The company's share value halved on 19 October 1987 and never recovered. The company went through a series of reorganizations, but the company never succeeded at making money on open systems and the last area with profits was sales to existing Sintran customers. From 1988 the company was gradually split up; parts were sold to foreign competitors while others were spun off as subsidiaries or sold. By 1993 all equity had been lost and the remaining parts of the company sold off or taken over by the creditors. The main parts of company were bought by Telenor.

Establishment

Norsk Data grew out of the development Simulation for Automatic Machinery 2 (SAM 2), a minicomputer developed at the Norwegian Defence Research Establishment (NDRE). The computer was ordered in 1966 for analysis of satellite data at Tromsø Satellite Station (TSS) and was the third computer built by NDRE. The main developers of the system were Rolf Skår, Per Bjørge, Lars Monrad-Krohn and Yngvar Lundh. SAM 2 was the first in Europe and among the first three in the world which used integrated circuits. The project was risky, as TSS originally had proposed buying an American computer and NDRE would have to buy such a computer if SAM 2 failed. As there was time between SAM 2 was completed and it had to be in Tromsø, the designers took it on a tour to Bergen and Trondheim. While in Bergen the group met an old fellow student, Ivar Aanderaa, who was working as an entrepreneur. He inspired the others of the joys of being self-employed and a discussion went on all night on the 23 April 1967 about starting up a computer-manufacturing company. Based on that they had a technological edge and believed to have good timing, a decision to start a company was made. For the entrepreneurs the main challenge was that their newly created computer was the property of the NDRE, which again had a strategic cooperation with Kongsberg, both government-owned. They expressed interest in the technology and considered themselves putting it into production. The other company which showed interest for the technology was the Horten-based Norcontrol, which was working on a project for ship automation but needed a computer to run the system. To raise capital, Skår took contact with his former college-mate Terje Mikalsen, who was working at Norcontrol. Mikalsen had married into a ship-owning family and was thus able to provide capital the others could not. At this time NDRE was working with Kongsberg for plans to build a computer for a field artillery system. Monrad-Krohn proposed that their company should try to get this contract, but after it was awarded to NDRE, they had increased difficulty finding investors. The company had estimated a need for NOK 600,000. A founding meeting was held on 7 July 1967 with fifteen people present. The largest investor was Mosvold Shipping Group which invested NOK 100,000, while remaining investors put in NOK 94,000. The company was established as A/S Nordata – Norsk Data-Elektronikk. As "Nordata" was already registered by a company in Trondheim, the name was changed to A/S Norsk Data-Elektronikk on 20 July. The name would change again somewhat later in 1977 to the more concise and recognisable Norsk Data, this being more accessible to the company's increasingly international audience.

The company's first offices were located at Ole Deviks vei 10 in Oslo, which was located in the facilities of a fan manufacturer. Operations commenced on 19 September with the three founders, Monrad-Krohn, Skår and Bjørge. They received the same wages as they had at NDRE. None of the entrepreneurs had any education or experience in business and operations started without a budget. The company's culture was inherited from NDRE—technology-oriented with focus on creativity and challenges. The first other employee was Tove Pedersen; she had an interview with the fan company, but had instead met up at ND. Monrad-Krohn did not let her inn on the error and instead carried out an interview and offered her a job, which she accepted.

Worked examples

Example 1 — a first encounter with History of Norsk Data

Start with the simplest possible case. Write down what History of Norsk Data claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to History of Norsk Data before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about History of Norsk Data ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of History of Norsk Data

In research
History of Norsk Data appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses History of Norsk Data in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
History of Norsk Data is common in secondary-school and first-year university syllabi. It links to neighbouring topics History of companies of Norway, History of computer companies, History of computing hardware, so understanding it makes those chapters shorter.
In everyday life
Look for History of Norsk Data outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
