Depends on what kind of "real time" you want. If you want hard real time, there isn't (to my knowledge) much in the way of UNIX. There are several UNIX-likes that do hard real time, and I'd suggest you look at Quantum's QNX or something like that. If you want sort real time, then all the vendors who are claiming "increased realtime support" will have some degree of realtime capabilities. DEC's OSF/1 offering has pretty good soft realtime stuff in the next release, based on the currently congealing POSIX standards. mjr. -- It is important to focus on writing software that is "adequate." Having one's software be "good" or even "excellent" is over-rated. If "good" were necessary or even important, DOS would not be the de facto standard operating system. -notebooks of a heretic
