111. IRMX: Intel Real time Multitasking eXecutive (OS, Intel), This provides a migration path for real-time applications to move to modern Windows technology. iRMX for Windows uses the same virtual machine technology as our INtime software so real-time and non-real-time applications run in separate virtual machines on a single computer, for cost-effective, reliable control that is easy to develop and maintain.

112. Intel 8080 was an early microprocessor designed and manufactured by Intel . The 8-bit CPU was released in April 1974 running at 2 MHz (at up to 500,000 instructions per second ), and is generally considered to be the first truly usable microprocessor CPU design. It was implemented using non-saturated enhancement-load NMOS , demanding extra voltages.

113. IBM stands for International Business Machines

114. IBSYS was the tape based operating system that IBM supplied with its IBM 7090 and IBM 7094 computers. IBSYS itself was really a basic monitor program, that read control card images placed between the decks of program and data cards of individual jobs. An IBSYS control card began with a "$" in column 1, immediately followed by a Control Name that selected the various IBSYS utility programs needed to set up and run the job.

115. BOS/360 (Basic Operating System/360) was an early IBM operating system . It came in 2 versions, 4K BOS and 8K BOS. The latter evolved into DOS/360 which some suggest was really version 6 of BOS. BOS in turn was preceded by BPS, Basic Programming Support. The first 360s to be shipped were the models 30 and 40.BOS was the first disk based operating system and was released in early 1965.Thus BOS was the only disk based operating system available at launch for a machine that was marketed as disk based.

116. TOS/360 (Tape Operating System/360) was an IBM operating system for the System/360 , used in the early days around 1965 to support the IBM 360 model 30 and similar platforms. TOS was a predecessor to IBM's DOS/360 . TOS died out quickly as disks such as the IBM 2311 and IBM 2314 became common with the System/360, whereas they had been an expensive luxury on the IBM 7090 .

117. Dis k Operating System/360 , also DOS/360 , or simply DOS , was an operating system for IBM mainframes . It was announced by IBM on the last day of 1964, and it was first delivered in June 1966.

118. DOS/360 was a single-job system, i.e. it did not support multitasking (although a version with limited multitasking, requiring 32 kB of memory, was later released). It used three memory partitions, but had little protection against programs overwriting other partitions. The three partitions were not specialised, but frequently one was used for spooling punched cards to disk, one for batch job execution, and one for spooling from disk to printers. Despite its limitations,DOS/360 became the most widely used operating system for processors with less than 256 KB of memory,

119. z/VSE (Virtual Storage Extended) is an operating system for IBM mainframe computers, the latest one in the DOS/360 lineage , which originated in 1965. It is less common than prominent z/OS and is mostly used on smaller machines. Primary z/VSE development occurs in IBM's Böblingen labs in Germany. VSE originally supported 24-bit addressing. As the underlying hardware evolved, VSE acquired support for 31-bit addressing. IBM released z/VSE Version 4 in 2007. z/VSE Version 4 requires 64-bit z/Architecture hardware and supports 64-bit real mode addressing.

120. A Real-Time Operating System ( RTOS) is a multitasking operating system intended for real-time applications. Such applications include embedded systems (programmable thermostats, household appliance controllers), industrial robots , spacecraft, industrial control (see SCADA ), and scientific research equipment. An RTOS will typically use specialized scheduling algorithms in order to provide the real-time developer with the tools necessary to produce deterministic behavior in the final system.

121. Operating System/Virtual Storage 1 , or OS/VS1 , was an IBM mainframe computer operating system designed to be run on IBM System/370 hardware. It was the successor to the System/360 's operating system MFT (Multiprogramming with a Fixed number of Tasks), a variant of OS/360 . OS/VS1, in comparison to its predecessor, was supporting virtual memory (then called virtual storage )

122. OS/VS2 was initially just OS/MVT plus virtual memory and VSAM. But in 1974 IBM released what it described as OS/VS2 release 2 but which was really a new operating system that was upwards-compatible with OS/VS2 release

123. MUSIC/SP (Multi-User System for Interactive Computing / System Product; originally "McGill University System for Interactive Computing") was developed at McGill University in the late 1960s from an IBM system called RAX (Remote Access).

124. OS/390 is an IBM operating system for the System/390 IBM mainframe computers .OS/390 was introduced in late 1995 in an effort, led by the late Randy Stelman, to simplify the packaging and ordering for the key, entitled elements needed to complete a fully functional MVS operating system package.

125. z/OS is a 64-bit operating system for mainframe computers , created by IBM . It is the successor to OS/390 , which in turn followed MVS and combined a number of formerly separate, related products. z/OS offers the attributes of modern operating systems but also retains much of the functionality originating in the 1960s and each subsequent decade that is still found in daily use.

126. CP/CMS was a time-sharing operating system of the late 60s and early 70s, known for its excellent performance and advanced features.

127. CMS , the Cambridge Monitor System and also Console Monitor System – but renamed Conversational Monitor System

128. three distinct versions: CP-40 /CMS, an important "one-off" research system that established the CP/CMS virtual machine architecture CP-67 /CMS, a reimplementation of CP-40/CMS for the IBM System/360-67 , and the primary focus of this article CP-370 /CMS, a reimplementation of CP-67/CMS for the System/370 – never released as such, but instead becoming the foundation of IBM's VM/370 operating system (announced in 1972 and still in use)

129. In addition to its role as the ancestor of the VM family, CP/CMS played an important role in the development of operating system theory, in the design of IBM's System/370 and later product lines, in the creation of the time-sharing industry, and in the creation of a self-supporting user community that anticipated today's free software movement

130. z/VM is the current version in IBM's VM family of virtual machine operating systems . z/VM was first released in October 2000 and remains in active use and development as of 2008.

131. The IBM System/34 was a minicomputer marketed by IBM from 1978 to 1983. It was a multi-user, multi-tasking successor to the single-user System/32 . Most notably, it included two very different processors, one based on System/32 and the second based on older System/3 .

132. The IBM System/36 was a minicomputer marketed by IBM from 1983 to 2000. It was a multi-user, multi-tasking successor to the System/34 .

133. OS/400 is IBM's operating system for its AS/400 and AS/400e line of business computers. Because OS/400 is closely attuned to the AS/400 hardware design and generally comes as part of the basic package, there is no alternative operating system to compete with it.

134. i5/OS is the name IBM has given to its newest release of OS/400 V5R3. i5/OS runs on IBM's i5 servers, which are based on IBM's Power5 microprocessors.

135. AIX ( Advanced Interactive eXecutive ) is the name given to a series of proprietary operating systems sold by IBM for several of its computer system platforms, based on UNIX System V with 4.3BSD -compatible command and programming interface extensions.

136. IBM PC DOS is a DOS operating system for the IBM Personal Computer , sold throughout the 1980s and 2000s. Official product name of "PC DOS" are as below: IBM Personal Computer Disk Operation System 1.0 (short-name: PC DOS 1.0) IBM Personal Computer Disk Operation System 2.0 (short-name:PC DOS 2.0) IBM Personal Computer Disk Operation System 3.0 (short-name:PC DOS 3.0) IBM DOS 4.0 (IBM changed product name) IBM DOS 5.0 IBM PC DOS 6.1 (IBM changed product name again. "PC DOS" is not short-name.) IBM PC DOS 6.3 IBM PC DOS 7 IBM PC DOS 2000 (IBM's last version)

137. OS/2 Warp=>In October 1994 IBM released OS/2 Warp, the most popular version of OS/2 and arguably one of the coolest operating systems ever (Warp Connect even said so on the box - "The totally cool way to run and network your computer" so it must be true). It was so good that some people use it even today - not me though, or at least not seriously. Its underpinnings weren't all that different from OS/2 version 2.11 but it was a great leap forward in terms of usability.

138. eComStation is a PC operating system based on OS/2 , published by Serenity Systems , USA. It includes several additions and accompanying software.

139. DPCX ( D istributed P rocessing C ontrol e X ecutive) was an operating system for the IBM 8100 . IBM hoped it would help their installed base of IBM 3790 customers migrate to the 8100 and the DPPX operating system. It was mainly deployed to support a word processing system, DOSF which was derived from the earlier IBM 3730 word processing system.

140. Like DPPX, it was written in the PL/S -like PL/DS language. The applications, including much of DOSF, however, were written an interpreted language that was "compiled" using the System/370 assembler macro facility. Distributed Processing Programming Executive was an operating system introduced by IBM, pre-installed on selected computer models in the 1980s.

141. K42 is an open-source research operating system for cache-coherent 64-bit multiprocessor systems. It was developed primarily at IBM Thomas J. Watson Research Center in collaboration with University of Toronto and University of New Mexico . The main focus of this OS is to address performance and scalability issues of system software on large-scale, shared memory ,

142. The IBM Series/1 Event Driven Language (EDL) was a computer language created for the Series/1 Event Driven Executive (EDX) operating system. The output was machine code for IBM Series/3 or Series/7, and interpreted on Series/1 by an emulator.

143. Although the Series/1 was grossly underpowered by today's standards, a robust multiuser operating environment (RPS) was available along with several additional high level languages for the RPS OS.

144. ICL I nternational Computers Ltd was a large British computer hardware , computer software and computer services company that operated from 1968 until 2002, when it was renamed Fujitsu Services Limited after its parent company, Fujitsu .

145. International Computers and Tabulators or ICT was formed in 1959 by a merger of the British Tabulating Machine Company (BTM) and Powers-Samas . In 1963 it also added the business computer divisions of Ferranti .

146. GEORGE was the name given to a series of operating systems released by International Computers and Tabulators (ICT) in the 1960s, for the ICT 1900 series of computers.

147. VME ( Virtual Machine Environment ) is a mainframe operating system developed by the UK company International Computers Limited (ICL).
