On February 4, 1997, Apple acquired NeXT and began development of the Rhapsody operating system. Rhapsody Main page: Software:Rhapsody (operating system) Later on, the developer tools and frameworks were released, as OpenStep, as a development platform that would run on other operating systems. NeXTSTEP originally ran on Motorola's 68k processors, but was later ported to Intel's x86, Hewlett-Packard's PA-RISC and Sun Microsystems' SPARC processors. NeXT also included object-oriented programming tools based on the Objective-C language that they had acquired from Stepstone and a collection of Frameworks (or Kits) that were intended to speed software development. NeXTSTEP also introduced a new windowing system based on Display PostScript that intended to achieve better WYSIWYG systems by using the same language to draw content on monitors that drew content on printers. NeXTSTEP used a hybrid kernel that combined the Mach 2.5 kernel developed at Carnegie Mellon University with subsystems from 4.3BSD. Development NeXTSTEP Main page: Software:NeXTSTEP
