Merge (software)
Merge is a software system which allows a user to run DOS/ Windows 3.1 on SCO UNIX, in an 8086 virtual machine. History Merge was originally developed to run DOS under UNIX System V Release 2 on an AT&T 6300 Plus personal computer. Development of the virtual machine began in late 1984, and AT&T announced the availability of the machine on 9 October 1985, referring to the bundled Merge software as Simultask. (The PC 6300 Plus shipped with MS-DOS in 1985 though, because its Unix System V distribution was not ready until the end of March 1986.) Merge was developed by engineers at Locus Computing Corporation, with collaboration from AT&T hardware and software engineers, particularly on aspects of the system that were specific to the 6300 Plus (in contrast to a standard IBM PC/AT). The AT&T 6300 Plus contained an Intel 80286 processor, which did not include the support for 8086 virtual machines ( virtual 8086 mode) found in the 80386 and later processors in the x86 fami ...

Locus Computing Corporation
Locus Computing Corporation was formed in 1982 by Gerald J. Popek, Charles S. Kline and Gregory I. Thiel to commercialize the technologies developed for the LOCUS (operating system), LOCUS distributed computing, distributed operating system at UCLA. Locus was notable for commercializing single-system image software and producing the Merge (software), Merge package which allowed the use of DOS and Windows 3.1 software on Unix systems. Locus was acquired by Platinum Technology Inc in 1995. Products AIX for IBM PS/2 and System/370 Locus was commissioned by IBM to produce a version of the AIX UNIX based operating system for the PS/2 and System/370 ranges. The single-system image capabilities of LOCUS (operating system), LOCUS were incorporated under the name of AIX TCF (transparent computing facility). OSF/1 AD for the Intel Paragon Locus was commissioned by Intel to produce a multiprocessor version of OSF/1 for the Intel Paragon a massively parallel NoRMA (No Remote Memory Access ...

Non-maskable Interrupt
In computing, a non-maskable interrupt (NMI) is a hardware interrupt that standard interrupt-masking techniques in the system cannot ignore. It typically occurs to signal attention for non-recoverable hardware errors. Some NMIs may be masked, but only by using proprietary methods specific to the particular NMI. With regard to SPARC, the non-maskable interrupt (NMI), despite having the highest priority among interrupts, can be prevented from occurring through the use of an interrupt mask. An NMI is often used when response time is critical or when an interrupt should never be disabled during normal system operation. Such uses include reporting non-recoverable hardware errors, system debugging and profiling, and handling of special cases like system resets. Modern computer architectures typically use NMIs to handle non-recoverable errors which need immediate attention. Therefore, such interrupts should not be masked in the normal operation of the system. These errors include non-r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microsoft Windows
Windows is a Product lining, product line of Proprietary software, proprietary graphical user interface, graphical operating systems developed and marketed by Microsoft.

Windows Interface Source Environment
Windows Interface Source Environment (or WISE) was a licensing program from Microsoft which allowed developers to recompile and run Windows-based applications on UNIX and Macintosh platforms. WISE SDKs were based on an emulation of the Windows API which could run on Unix and Macintosh platforms. History WISE was issued in 1994. WISE software development kits were not directly provided by Microsoft. Instead, Microsoft established partnerships with several software providers (which needed to have access to Windows internals source code), which in turn sold WISE SDKs to end-users. A few software providers provided WISE SDKs or emulators, mainly: * Mainsoft developed a product called Mainwin, which provided an implementation of MFC on Unix platforms. * Bristol Technology Inc. developed Wind/U, which ran on top of Motif. * Insignia Solutions provided an emulator called '' Softwindows.'' * Locus Computing Corporation provided an emulator called '' Merge.''

DR DOS 6
DR-DOS is a disk operating system for IBM PC compatibles, originally developed by Gary A. Kildall's Digital Research, Inc. and derived from Concurrent PC DOS 6.0, which was an advanced successor of CP/M-86. Upon its introduction in 1988, it was the first DOS that attempted to be compatible with IBM PC DOS and MS-DOS. Its first release was version 3.31, named so that it would match MS-DOS's then-current version. DR DOS 5.0 was released in 1990 as the first to be sold in retail; it was critically acclaimed and led to DR DOS becoming the main rival to Microsoft's MS-DOS, who quickly responded with its own MS-DOS 5.0 but releasing over a year later. It introduced a graphical user interface layer called ViewMAX. DR DOS 6.0 was released in 1991; then with Novell's acquisition of Digital Research, the following version was named Novell DOS 7.0 in 1994. After another sale, to Caldera, updated versions were released partly open-source under the Caldera moniker, and briefly as Ope ...

UnixWare 1
UnixWare is a Unix operating system. It was originally released by Univel, a jointly owned venture of AT&T's Unix System Laboratories (USL) and Novell. It was then taken over by Novell. Via Santa Cruz Operation (SCO), it went on to Caldera Systems, Caldera International, and The SCO Group before it was sold to UnXis (now Xinuos). After the acquisition of SCO by Caldera, the name was briefly changed to Open UNIX before being reverted to the original name in the next release. Binary distributions of UnixWare are available for x86 architecture computers. UnixWare is primarily marketed and deployed as a server operating system. History Univel (1991–1993) After the SVR4 effort to merge SunOS and System V, AT&T's Unix System Laboratories (USL) formed the Univel partnership with Novell to develop a desktop version of Unix for i386 and i486 machines, codenamed "Destiny".

Univel
Univel, Inc. was a joint venture of Novell and AT&T's Unix System Laboratories (USL) that was formed in December 1991 to develop and market the Destiny desktop Unix operating system, which was released in 1992 as UnixWare 1.0. Univel existed only briefly in the period between AT&T initially divesting parts of USL in 1991, and its eventual outright purchase by Novell, which completed in June 1993, thereby acquiring rights to the Unix operating system. Novell merged USL and Univel into their new Unix Systems Group (USG). Beginning Novell was the leader in network operating system software, with its product NetWare, while Unix System Laboratories was an AT&T majority-owned entity responsible for the development and maintenance of one of the main branches of the Unix operating system, the UNIX System V Release 4 source code product. The idea to combine forces originated during 1991, with USL chief Roel Pieper believing that the advent of 32-bit applications and workgroup com ...
