Lycklama .AB The MINI-UNIX Operating System is basically the UNIX Operating System re-written in C to run on a PDP-11 processor without a segmentation unit. The system supports all of the standard system calls of UNIX with the exception of: ptrace, pipe, prof, getgid and setgid. The entire system resides in 12K words of memory and is written in the C language. An emulation package is included for those machines which do not support the extended instruction set (e.g. mul, div, ash, etc.). The system will support up to 4 users using a simple round-robin time-slice scheduling algorithm. It provides an inexpensive software development system in a UNIX time-sharing environment for those installations with insufficient hardware to support the full standard UNIX Operating System. .AE .CS 8 2 10 0 0 4
