* 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.

" Mac " McLoughlin ( another long time IBM executive ) led the company's field sales organization after starting up the Western U. S. Area of Operations.

Major U. S. companies operating in the country include ACS, CMS Energy, Coca Cola, S. C. Johnson, Ralston Purina, Star-Kist, A. H. Robins, Sterling, Pfizer, IBM, 3M, Motorola, Stewart & Stevenson, PriceWaterhouseCoopers, and National Cash Register ( NCR ).

IBM punched card Accounting Machines at the U. S. Social Security Administration in 1936.

In computing, the KOMPILER was one of the first language compilation and runtime systems for International Business Machines ' IBM 701, the fastest commercial U. S. computer available in 1955.

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

The S / 360 ( excepting the 360 / 20 ) was replaced by the compatible System / 370 range in 1970 and 360 / 20 users were targeted to move to the IBM System / 3.

The U. S. Federal Aviation Administration operated the IBM 9020, a special cluster of modified System / 360s for air traffic control, from 1970 until the 1990s.

* IBM v. Papermaster ( No. 08-9078, 2008 U. S. Dist ): Mark Papermaster moving from IBM to Apple computer in 2008.

During this same period, IBM became more deeply involved in the war effort for the U. S., focusing on producing large quantities of data processing equipment for the military and experimenting with analog computers.

Watson, Sr. also developed the " 1 % doctrine " for war profits which mandated that IBM receive no more than 1 % profit from the sales of military equipment to U. S. Government.

He left IBM to attend graduate school at UCLA where he earned his M. S.

In October 1986, the IBM S / 38 announced " checksum ".

IBM also developed, but never officially released, TSS / 360, a time-sharing system for the S / 360 Model 67.

Several operating systems for the IBM S / 360 and S / 370 architectures were developed by third parties, including the Michigan Terminal System ( MTS ) and MUSIC / SP.

MAD ( Michigan Algorithm Decoder ) is a programming language and compiler for the IBM 704 and later the IBM 709, IBM 7090, IBM 7040, UNIVAC 1107, UNIVAC 1108, Philco 210-211, and eventually the IBM S / 370 mainframe computers.
