MacWorks Plus was a complete implementation (port) of the Macintosh Plus 128K ROM on the Apple Lisa and Macintosh XL computer systems,  a contract developer named Chuck Lukaszewski, who was responsible for versions up through 1.1(h), which supported up to which graphical user interface-based operating system for Macintosh computers, and was shipped with various Macintosh computers until it was succeeded by System 7 in 1991?
MacWorks Plus MacWorks Plus was a complete implementation (port) of the Macintosh Plus 128K ROM on the Apple Lisa and Macintosh XL computer systems, and introduced in August 1988. It was developed for Sun Remarketing of Cache Valley, Utah, under license from Apple Inc., by a contract developer named Chuck Lukaszewski, who was responsible for versions up through 1.1(h), which supported up to Macintosh System 6.0.3. Dafax Processing Corp. with the assistance of Query Engineering, Inc. then further developed the environment to MacWorks Plus II, which continued Macintosh system support up to System 6.0.8 with the "Basic" version, and introduced a "Pro" version to extend support to the maximum possible for any 68000 processor: System 7.5.5. Prior to MacWorks Plus, the maximum system supported by its predecessor MacWorks XL was System 3.2.
Development of Windows 95 The initial design and planning of Windows 95 can be traced back to around March 1992, just after the release of Windows 3.1. At this time, "Windows for Workgroups 3.1" and Windows NT 3.1 were still in development and Microsoft's plan for the future was focused on Cairo. Cairo would be Microsoft's next-generation operating system based on Windows NT and featuring a new user interface and an object-based file system, but it was not planned to be shipped before 1994 (Cairo would eventually partially ship in July 1996 in the form of Windows NT 4.0, but without the object-based file system, which would later evolve into WinFS).
