In 1970, Karpiński decided to establish his own institution to work on his new idea, a minicomputer of original architecture, for which he sought backing from state officials. Karpiński was given permission to found Microcomputers' Construction Plant (Zakład Budowy Mikrokomputerów) in Warszawa-Włochy in 1970. The basis for the computer's construction was the fruit of the joint-venture agreement between the Polish state (represented by Metronex, a foreign trade office) and British private partners companies Data-Loop and MB Metals. Karpiński, who orchestrated the agreement, was appointed technical director, fully responsible for the engineering aspect of the venture. The parts and finances were to be supplied by the British, but the entire construction and production process was to be done in Poland, something that Karpiński strongly insisted on. MB Metals and Data-Loop were given rights to sell the computer in all countries, except Poland. The companies were also solely responsible for the products promotion and distribution.
