Miray Software has released [scroll down a bit] the first version of its newly developed embedded RTOS, Symobi. “Symobi was introduced in professional circles for the first time on the Systems 2006 exposition. Symobi is a graphical RTOS with a newly designed architecture, according to state-of-the-art technology. It is based on the microkernel system µnOS, which was also developed by Miray Software. Therefore, Symobi has its main characteristics – real-time, stability, portability, and modularity – and expands it with new services. The research team of Prof. Dr. Uwe Baumgarten of the Technical University Munich is also involved in the development.” There are screenshots, as well as a live CD (for x86 and the Pegasos II/ODW).
