ABSTRACT
NEXTSTEPTM is an operating system from NeXT™ Computer Inc. It is based on BSD Unix™ running on a Mach kernel. Nearly all interaction is done through a graphical user interface (GUI). The GUI uses a unified PostScript™ imaging model for displaying text and graphics on the screen or on the printer. It runs on several types of hardware ranging from industry standard PCs to high end workstations from HP. Versions for other hardware are being announced regularly. A version called OPENSTEP™ is planned for use on Sun™ workstations running Solaris™. It is distributed in two parts: NEXTSTEP User and NEXTSTEP Developer.
