TROPIX – a multi-user and multitasking Operating System, based on the UNIX philosophy, developed at the Electronic Computing Center of the Federal University of Rio de Janeiro (NCE/UFRJ).

TROPIX was initially designed between 1982 and 1986 (at the time under the name PLURIX) for the PEGASUS computer. This computer was also built at NCE, and was based on the MOTOROLA 68010/20 processors. The system was ported in 1987 to the ICARUS computer, also based on these same processors. In 1994, transport for the INTEL line of processors (386, 486, Pentium) began, and since 1996 TROPIX has been operational on PCs, being used in several computers.

TROPIX has several uses, such as the study/learning/use of an operating system based on the UNIX philosophy, the development of programs (“software”) and the implementation of servers for the INTERNET (this page you are reading is coming from the server WWW from a computer running TROPIX). Furthermore, it is ideal for use in operating systems courses, as it contains primitives for “light” processes (“threads”), shared memory, user-level semaphores, among others.

Distribution of TROPIX is free, according to the GNU public license.

Currently, the development and maintenance of TROPIX is being carried out by Pedro Salenbauch and Oswaldo Vernet.

The continuation of this work is a posthumous tribute to Newton Faller, the great creator of the PEGASUS, PLURIX, TROPIX projects and many others.
