OpenStep is an operating system based on the Mach micro-kernel architecture. System services, including a version of BSD UNIX, sit on top of the microkernel and the Workspace Manager (the GUI) runs in front of all of it. A diagramatic abstraction of NextStep on black hardware looks like this: OpenStep is a multi-tasking, multi-threading, multi-user OS and uses Display PostScript for drawing to screen. The last rev was 4.2. Previous revs were known as NextStep. OpenStep was released for Intel, Motorola 68K, HP and Sun SPARC hardware.
