Harmony is a message passing real time operating system designed for robotics and multi-processor systems. A single processor multitasking version called WS-Harmony runs on the AT. It can communicate with MS-DOS. A multiprocessor version that runs on the 680x0 family of processors can be used stand alone, or on a VMEbus based system. One uses Turbo C to program the AT based applications and Microtec C to cross-compile to the 680x0 target. There is also a source level cross debugger to support multiprocessor target debugging from the AT host. WS-Harmony was designed as a tool to teach peaople how to do real time programming on a low cost computer like an AT. It turns out that it is also a good evaluation tool and is very useful for embedded PC or 80286 applications.
