VRTX was a nice little ROM-based real-time kernel, limited but very solid, and unchanged for several years. Then Hunter and Ready came out with a new version (3), changed the interface for all the system calls, and changed the semantics of several of them, for no really pressing reason. Not a good tactic from a company that's big on putting software components in ROM. John Nagle
