* Attached Support Processor, one of the two early IBM System / 360 programs that replaces the native SPOOL facilities of OS / 360 ; the other was Houston Automatic Spooling Priority ( HASP ).

Originally released for the IBM 6150 RISC workstation, AIX now supports or has supported a wide variety of hardware platforms, including the IBM RS / 6000 series and later IBM POWER and PowerPC-based systems, IBM System i, System / 370 mainframes, PS / 2 personal computers, and the Apple Network Server.

AIX Version 1, introduced in 1986 for the IBM 6150 RT workstation, was based on UNIX System V Releases 1 and 2.

Among other variants, IBM later produced AIX Version 3 ( also known as AIX / 6000 ), based on System V Release 3, for their IBM POWER-based RS / 6000 platform.

Since 1990, AIX has served as the primary operating system for the RS / 6000 series ( later renamed IBM eServer pSeries, then IBM System p, and now IBM Power Systems ).

In 2003, the SCO Group alleged that ( among other infractions ) IBM had misappropriated licensed source code from UNIX System V Release 4 for incorporation into AIX ; SCO subsequently withdrew IBM's license to develop and distribute AIX.

The original AIX ( sometimes called AIX / RT ) was developed for the IBM 6150 RT workstation by IBM in conjunction with Interactive Systems Corporation, who had previously ported UNIX System III to the IBM PC for IBM as PC / IX.

AIX / 370 was released in 1990 with functional equivalence to System V Release 2 and 4. 3BSD as well as IBM enhancements.

* Auxiliary Storage Pool, a group of disk drives in the IBM i ( aka OS / 400 ) operating system

The AIX family of operating systems debuted in 1986, became the standard operating system for the RS / 6000 series on its launch in 1990, and is still actively developed by IBM.

In the late 1990s, under Project Monterey, IBM and the Santa Cruz Operation planned to integrate AIX and UnixWare into a single 32-bit / 64-bit multiplatform UNIX with particular emphasis on running on Intel IA-64 ( Itanium ) architecture CPUs.

* 1964 – IBM announces the System / 360.

During the early 1960s, while also active in ASCII standardization, IBM simultaneously introduced in its product line of System / 360 the 8-bit Extended Binary Coded Decimal Interchange Code ( EBCDIC ), an expansion of their 6-bit binary-coded decimal ( BCDIC ) representation used in earlier card punches.

Gene Amdahl's seminal 1964 article on IBM System / 360 used 1K to mean 1024.

The effort was sufficiently complete that during the summer of 1973 the Unix kernel for the PDP-11 was rewritten in C. During the 1972 – 73 period there was a need to port to Honeywell 635 and IBM 360 / 370 machines, so Mike Lesk wrote the " portable I / O package " which would become the C " standard I / O " routines.

TWA canceled the project in 1970, acquiring one IBM System / 360 Model 75, two IBM System / 360 model 65s, and IBM's PARS software for its reservations system.

In 1964 IBM introduced its System / 360 computer architecture which was used in a series of computers that could run the same programs with different speed and performance.

The System / 360 architecture was so popular that it dominated the mainframe computer market for decades and left a legacy that is still continued by similar modern computers like the IBM zSeries.

One notable late CPU design that uses clock gating is that of the IBM PowerPC-based Xbox 360.

The original System / 360 models of IBM mainframe had read-only control store, but later System / 360, System / 370 and successor models loaded part or all of their microprograms from floppy disks or other DASD into a writable control store consisting of ultra-high speed random-access read-write memory.

* The DOS / 360 initial / simple operating system for the IBM System / 360 family of mainframe computers ( it later became DOS / VSE, and was eventually just called VSE ).

EBCDIC () was devised in 1963 and 1964 by IBM and was announced with the release of the IBM System / 360 line of mainframe computers.

While IBM was a chief proponent of the ASCII standardization committee, they did not have time to prepare ASCII peripherals ( such as card punch machines ) to ship with its System / 360 computers, so the company settled on EBCDIC.

* FORTRAN H, a Fortran implementation for the IBM System / 360 and System / 370 mainframes

" Brooks responded " The most important single decision I ever made was to change the IBM 360 series from a 6-bit byte to an 8-bit byte, thereby enabling the use of lowercase letters.

Current mainframes in IBM's line of business computers are developments of the basic design of the IBM System / 360.

As software became more complex and important, the cost of supporting it on so many different designs became burdensome, and this was one of the factors which led IBM to develop System / 360 and its operating systems.

The second generation ( transistor-based ) products were a mainstay of IBM's business and IBM continued to make them for several years after the introduction of the System / 360.

In 1988, IBM announced AIX / 370, also developed by Locus Computing.

SunSoft, HP, IBM and USL announced CDE in June 1993 as a joint development within the Common Open Software Environment ( COSE ) initiative.

Compaq PortableIn November 1982 Compaq announced their first product, the Compaq Portable, a portable IBM PC compatible personal computer.

It was later ported to the IBM PC and released when the PC was announced in 1981.

In June 2011, IBM announced that it had successfully used graphene-based FETs in an integrated circuit.

In 1983, Microsoft announced the development of Windows, a graphical user interface ( GUI ) for its own operating system ( MS-DOS ), which had shipped for IBM PC and compatible computers since 1981.

* IBM announced in January 2009 that it was opening its first U. S. programming center in the former MSU Federal Credit Union headquarters in East Lansing for application software for governments, universities, etc.

The IBM System / 360 ( S / 360 ) was a mainframe computer system family announced by IBM on April 7, 1964, and delivered between 1965 and 1978.

IBM initially announced a series of six computers and forty common peripherals.

The S / 360-67, announced in August 1965, was the first production IBM system to offer dynamic address translation hardware to support time-sharing.

Before the 67, IBM had announced models 64 and 66, DAT versions of the 60 and 62, but they were almost immediately replaced by the 67 at the same time that the 60 and 62 were replaced by the 65.

IBM announced the delivery of the next release of TPF, dubbed z / TPF V1. 1, in September 2005.

But on the eve of Signature's release, IBM announced a strategic decision to withdraw completely from the desktop software market, shocking XyQuest and leaving Signature in limbo.

As the Tandy 1000 line outlasted the PCjr by many years ( and in fact did not make it to market until shortly before IBM announced the discontinuation of the PCjr ) these graphics and sound standards became known as " Tandy-compatible " or ( for the graphics ) " TGA " ( standing for Tandy Graphics Adapter ) and many software packages of the era listed their support for Tandy standard hardware on the package.

* As an example of the impact of deep-ultraviolet excimer laser photolithography, in continuing the advances in semiconductor chip fabrication, IBM researchers announced in early 2006 that they had developed a technique to print circuitry only 29. 9 nm wide using 193 nm ArF excimer laser lithography.

In April 2008, IBM announced its integration with the System p platform.

The IBM System i, then known as the AS / 400, was the continuation of the System / 38 database machine architecture ( announced by IBM in October 1978 and delivered in August 1979 ).

In April 2008, IBM announced a rebranding of the System p and its unification with the System i platform.

Other metal gates have made a comeback with the advent of high-k dielectric materials in the CMOS process, as announced by IBM and Intel for the 45 nanometre node and beyond.
