MERT – Multi-Environment Real-Time (MERT), later renamed UNIX Real-Time (UNIX-RT) is a multi-environment real-time operating system for the Digital Equipment PDP-11/45 and 11/70 computers. It is a hybrid time-sharing and real-time operating system developed in the 1970s at Bell Labs for use in embedded minicomputers .
Real-time response to processes is achieved by means of preemptive priority scheduling.
UNIX is a general-purpose, interactive time-sharing operating system for the DEC PDP-11 and Interdata 8/32 computers. Since it became operational in 1971, it has become quite widely used. This paper discusses the strong and weak points of UNIX and some areas where we have expended no effort.
