PC-MOS – an advanced operating system designed to provide Multi-Tasking and Multi-User capability to personal computers. MOS controls requests made on the computer’s hardware resources, including the central processing unit (CPU), random access memory (RAM), disk drives, printers, serial ports, and other peripherals.
Application programs and utilities call upon MOS for communicating directly with the hardware to obtain the desired results. As ‘a middle-manager, MOS must control keystrokes, screen and printer output, disk access, RAM allocations, time checks, priority changes and much more — for multiple programs and users, all at the same time.
PC-MOS is offered in a single-user, multi-tasking version that provides the capability of performing multiple tasks on a single computer. MOS is also available in 5-user, 9-user, and 25-user versions. If you have a single-user version of MOS, you have the capability of upgrading to a 5-user, 9-user, or 25-user system. You may also upgrade from the 5-user to the 9- or 25-user version as your processing demands increase. Any files or programs you are currently running should not be affected as you upgrade.
The project founder is The Software Link (TSL).
The PC-MOS successor is PC-MOS/386.
