Development began in the late 1980s with early versions available via File Transfer Protocol (ftp) as early as 1993. OAR Corporation managed the RTEMS project in cooperation with a steering committee until the early 2000s when project management evolved into a subset of the core developers managing the project. In 2014, hosting was moved from OAR Corporation to the Open Source Lab at Oregon State University.
