RTSI was formed in October of 1993 when Mizar Inc. changed its strategic direction from 68K to DSP. RTSI has focused on OS-9 based projects since that time. As the customer base expanded and needs were met, RTSI modified its facilities to react quickly to customer demands. Our experience with Microware based software dates back to Microware's inception. Today RTSI LLC. is the leading consulting firm in OS-9 and real time related systems solutions.  In February 2013 RTSI LLC, Microsys Gmbh, and Freestation Inc purchase all of the rights to Microware OS-9 From Radisys Corporation.   Since that time we have been updating and adding new feature to OS-9.
