Plurix is a Unix-like operating system developed in Brazil in the early 1980s. ==Overview== Plurix was developed in the Federal University of Rio de Janeiro (UFRJ), at the Electronic Computing Center (NCE). The NCE researchers, after returning from postgraduate courses in the USA, attempted to license the UNIX source code from AT&T in the late 1970s without success. In 1982, due to AT&T refusing to license the code, a development team led by Newton Faller decided to initiate the development of an alternative system, called Plurix ( * *), using as reference UNIX Version 7, the most recent at the time, that they had running on an old Motorola computer system. In 1985, the Plurix system was up and running on the Pegasus 32-X, a shared-memory, multi-processor computer also designed at NCE. Plurix was licensed to some Brazilian companies in 1988. Two other Brazilian universities also developed their own UNIX systems: Universidade Federal de Minas Gerais (UFMG) developed the DCC-IX operating system, and University of São Paulo (USP) developed the REAL operating system in 1987. The NCE/UFRJ also offered technical courses on OS design and implementation to local computer companies, some of which later produced their own proprietary UNIX systems. In fact, these Brazilian companies first created an organization of companies interested in UNIX (called API) and tried to license UNIX from AT&T. Their attempts were frustrated at the end of 1986, when AT&T canceled negotiations with API. Some of these companies, EDISA, COBRA, and SOFTEC, invested in the development of their own systems, EDIX, (SOX ) and ANALIX, respectively. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Plurix」の詳細全文を読む スポンサード リンク
