A UNIX OPERATING SYSTEM ADAPTED FOR A TECHNICAL PERSONAL-COMPUTER

The HP-UX operating system for HP's Integral Personal Computer provides a number of very significant challenges by eliminating the need for a hard disk and allowing the installed flexible disk to be removed whenever a disk access is not occurring; by eliminating the need for complex system configuration and user administration of the operating system; by simplifying the human interface with the aid of a windowed environment to make the system easier to use; and providing a measure of real-time capability for instrumentation control.
