SWEDIN WEBER STATE UNIVERSITY DAVIS ABSTRACT In 2006, IBM ended their support of OS/2, closing the book on an ambitious effort to create a modern operating system for the personal computer. IBM and Microsoft released the OS/2 operating system in December 1987 to replace the primitive DOS with a more sophisticated, preemptive multitasking operating system for personal computers. This article argues that OS/2 failed because of the U.S.-Japan Semiconductor Trade Agreement of 1986, subsequent accusations of DRAM chip dumping by the United States, and the resulting tariffs on Japanese memory chips, led to a memory chip shortage that drove up memory prices.

  • Accessing Windows Applications from Unix and Vice Versa

This implies that even if eventually migrating to another environment, one still has to deal with coexistence among environments in the interim. In many com- panies it would make good business sense not to migrate legacy systems at all. Instead, it may be better to develop new systems in the desired en- vironment and phase out the legacy applications. The data created by the legacy applications is important and one must ensure that data can be ac- cessed from a new environment. Coexistence considerations are very im- portant in this case.

  • MICROSOFT WINDOWS Early Versions Main Articles: Windows 1.0
    MICROSOFT WINDOWS Early versions Main articles: Windows 1.0, Windows 2.0, and Windows 2.1x Windows 1.0, the first version, released in 1985 The history of Windows dates back to September 1981, when Chase Bishop, a computer scientist, designed the first model of an electronic device and project "Interface Manager" was started. It was announced in November 1983 (after the Apple Lisa, but before the Macintosh) under the name "Windows", but Windows 1.0 was not released until November 1985.[5] Windows 1.0 achieved little popularity and was to compete with Apple's own operating system. Windows 1.0 is not a complete operating system; rather, it extends MS-DOS. The shell of Windows 1.0 is a program known as the MS- DOS Executive. Components included Calculator, Calendar, Cardfile, Clipboard viewer, Clock, Control Panel, Notepad, Paint, Reversi, Terminal and Write. Windows 1.0 does not allow overlapping windows. Instead all windows are tiled. Only modal dialog boxes may appear over other windows. Windows 2.0 was released in December 1987 and was more popular than its predecessor. It features several improvements to the user interface and memory management.[citation needed] Windows 2.03 changed the OS from tiled windows to overlapping windows. The result of this change led to Apple Computer filing a suit against Microsoft alleging infringement on Apple's copyrights.[6][7] Windows 2.0 also introduced more sophisticated keyboard shortcuts and could make use of expanded memory. Windows 2.1 was released in two different versions: Windows/286 and Windows/386. Windows/386 uses the virtual 8086 mode of Intel 80386 to multitask several DOS programs and the paged memory model to emulate expanded memory using available extended memory.

  • Comparing the SAS System Under OS/2 and Microsoft Windows Which
    comparing the SAS System under OS/2 and Microsoft Windows Which is right for you? Mark W. Cates SAS Institute Inc. Abstract As we enter into the 1990s, two operating systems are available to enhance productivity forcEersonalcomput­ ers and provide a future platform for PC software users. The two environments, OS/2 • version 1.3 and Microsoft Windows ® 3.0 provide fundamentally the same user interface and similar features, but the underly­ ing operating systems are radically different. Today, corporations large and small are deciding which operat­ ing system should be used in their organizations and for which applications. The platform for more powerful and mission critical applications is clearly OS/2. However, with the introduction and overwhelming accep­ tance of Windows 3.0, supporting DOS compatibility, a graphical user interface compatible with Presentation Manager, and access to extended and virtual memory, a large memory alternative to OS/2 is available. This paper discusses these two environments with respect to the SAS System. The paper presents the advantages and disadvantages of the operating systems, configuration issues, and future directions, with respect to the SAS System. Issues that are particularly important to the SAS System are described in detail. Finally, the implications of the new 32 bit OS/2 version 2.0 are presented. (In this paper, Microsoft Windows 3.0 will be referred to as an operating system. Actual~, Microsoft Windows is a layered operating environment that runs on top of the operating system PC DOS •. For purposes of this paper, the distinction between operating environment and operating system is not important.) SAS release status for OS/2 and Windows Version 6.06 of the SAS System has been in production for OS/2 1.2 and 1.3 Standard and Extended Edition, as well as Microsoft's OEM versions since November 1990.
