PMOS is a large library of Modula-2 modules, distributed in source form. Its primary purpose is to make it easy to write multitasking programs for real-time and/or embedded applications. However it also contains a number of modules of interest even if you don't want to write multitasking code: screen windows and screen graphics modules, various device drivers, and a variety of utility modules. PMOS is free for non-profit use. As distributed, PMOS is written for use on IBM-PC compatible hardware; but large parts of it are portable. To obtain PMOS, fetch the file pmos21.zip in this directory (don't forget to set binary mode for ftp transfers), and unzip into a disk directory of your choice. If you don't have a suitable unzipper, fetch the program unz50p1.exe from this directory. If you are not running MS-DOS, look for the InfoZip unzipper for your system at one of the popular ftp archive sites. After unzipping, you will find another README file among the unzipped files. Read it for further installation information. If you have trouble fetching from this site, look for pmos21.zip at one of the following places: - Fat City BBS, San Diego (USA); supports anonymous "gopher" type access.
