, the largest French computer manufacturer, which had the second highest market share in France, after IBM. Following this partial takeover, known as "Affaire Bull", GE-Bull dropped two Bull computers from its product line.

Responsibility for administering the plan was given to a newly created government agency, Délégation à l'informatique, answering directly to the prime minister.

As part of the program, in December 1966, the Compagnie internationale pour l'informatique (CII) was established as a manufacturer of commercial and scientific computers, initially under licence from Scientific Data Systems. The new company was intended to compete not only in the process control and military market, where its staff was already seasoned, but also in the office computing sector of the French market, where IBM and Bull were dominant at the time. The plan enacted government subsidies for CII between 1967 and 1971, and was reconducted for another four years. A minor side of the plan was devoted to peripherals, while CII's main parent company, Thomson-CSF, received government support to develop its semiconductor plants and R & D.

On the research side, the program also led to the creation of L'Institut de recherche en informatique et en automatique (IRIA) in 1967, which later became INRIA. It was accompanied with a vast educational effort in programming and computer science.

In the late 1960s, CII shipped its new, internally designed mainframes (Iris 50 and Iris 80), and developed a mini-computer, Mitra 15, which became a commercial success in the following decade. The company also produced competitive magnetic peripherals in cooperation with CDC

In 1971, CII began negotiations with Siemens and Philips to form a joint European company, Unidata, which shipped its first computers in 1974. Yet a new President of the Republic was elected then, former Finance minister Giscard d'Estaing, who was a strong opponent of the Plan Calcul; meanwhile, CII's sleeping partner, CGE-Alcatel, woke up to oppose the domination of its archrival Siemens over the European computer industry. Unidata was terminated and CII was absorbed into Honeywell-Bull in 1976.
