UNIX on a micro-processor

A modified version of the UNIX Operating System has been written to run on the LSI-11 micro-computer with 20K words of primary memory and floppy disks for secondary storage. This configuration permits most of the UNIX user programs to run on the LSI-11 micro-computer. The main programming language used is the structured high-level language, C. A background process as well as foreground processes may be run. A set of subroutines has been written to interface to the file system on the floppy diskettes. Asynchronous read/write routines are also available to the user. The LSI-UNIX system (LSX) has appeal as a stand-alone system for dedicated applications. It also has many potential uses as an intelligent terminal system. The decreasing costs of the hardware components make such a system a potential candidate for a very powerful and inexpensive personal computer system.
