* IBM Floating Point Architecture

Floating point became a focus for the America Project, and IBM was able to use new algorithms developed in the early 1980s that could support 64-bit double-precision multiplies and divides in a single cycle.

The hamlet is now partly a wooded, unpopulated area between IBM and the Clinton Point Quarry owned by Tilcon, Inc., and part of land that rests on a Spackenkill residential community known informally as Crown Heights.

His works are in the White House, the National Gallery of Art, the U. S. Supreme Court, the Pentagon, Walter Reed Hospital, the U. S. Military Academy at West Point, the U. S. Naval Academy, the Eisenhower Museum in Abilene, Kansas, the Legion of Honor Gallery in Paris ; the American Embassy in London, IBM corporate headquarters, Cornell University, Columbia University, Harvard University, the Harry Truman Library and others.

Backplanes have grown in complexity from the simple Industry Standard Architecture ( ISA ) ( used in the original IBM PC ) or S-100 style where all the connectors were connected to a common bus.

This technical leadership and the rivalry with IBM was emphasized when the Systempro server was launched in late 1989-this was a true server product with standard support for a second CPU and RAID, but also the first product to feature the EISA bus, designed in reaction to IBM's MCA ( MicroChannel Architecture ).

* Character Data Representation Architecture ( CDRA ) from IBM Contains IBM's official information on codepages and charsets.

The Extended Industry Standard Architecture ( in practice almost always shortened to EISA and frequently pronounced " eee-suh ") is a bus standard for IBM PC compatible computers.

IBM Mainframes: Architecture and Design, 2nd ed.

Industry Standard Architecture ( ISA ) is a computer bus standard for IBM PC compatible computers introduced with the IBM Personal Computer to support its Intel 8088 microprocessor's 8-bit external data bus and extended to 16 bits for the IBM Personal Computer / AT's Intel 80286 processor.

) In late 2000 IBM introduced 64-bit z / Architecture, acquired numerous software companies such as Cognos and introduced those software products to the mainframe.

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.

To be eligible for sub-capacity licensing, a z / OS customer must be running in 64-bit mode ( which requires z / Architecture hardware ), must have completely eliminated OS / 390 from the system, and must e-mail IBM monthly sub-capacity reports.

While the PAD function defined by X. 28 and X. 29 specifically supported asynchronous character terminals, PAD equivalents were developed to support a wide range of proprietary intelligent communications devices, such as those for IBM System Network Architecture ( SNA ).

The IBM AT compatible bus was later named the Industry Standard Architecture bus by manufacturers of compatible computers.

Apple was the dominant purchaser of PowerPC chips from IBM and Freescale Semiconductor and even though they abandoned the platform, further development of AltiVec is continued in several Power Architecture designs from Freescale and IBM.

In the original IBM PC, there was only one Intel 8237 DMA controller capable of providing four DMA channels ( numbered 0-3 ), as part of the so-called Industry Standard Architecture, or ISA.

However, recognising the benefits of vector processing IBM developed Virtual Vector Architecture for use in supercomputers coupling several scalar processors to act as a vector processor.

In February 1990, the first computers from IBM to incorporate the POWER Architecture (" Performance Optimized With Enhanced RISC ") were called the " RISC System / 6000 " or RS / 6000.

IBM introduced the Industry Standard Architecture ( ISA ) bus, with the IBM PC in 1981 ; it was then called the PC bus.

DIGITAL published its first DNA specification at about the same time that IBM announced its Systems Network Architecture ( SNA ).

IBM maintains that their license was irrevocable, and continued to sell and support the product until the litigation was adjudicated.

" The IBM COMTRAN language invented by Bob Bemer was also drawn upon, but the FACT language specification from Honeywell was not distributed to committee members until late in the process and had relatively little impact.

Apparently his work remained largely unknown to engineers in the UK and US until much later, although at least IBM was aware of it as it financed his post-war startup company in 1946 in return for an option on Zuse's patents.

It was employed for the IBM PC / AT, introduced in 1984, and then widely used in most PC / AT compatible computers until the early 1990s.

New Model M keyboards continued to be manufactured for IBM by Lexmark until 1996, when Unicomp purchased the keyboard technology.

Although IBM began indicating shortly after the release of Warp 4 that OS / 2 would eventually be withdrawn, the company did not end support until December 31, 2006.

The IBM System / 360 ( announced in 1964 but not delivered until 1966 ) was designed as a common machine architecture for both groups of users, superseding all existing IBM architectures.

It used a traditional typebar mechanism, not the " golfball " IBM Selectric typewriter mechanism, which was not introduced until the next year.

The term did not become widely known and used, however, until the early 1980s, essentially synonymous with the introduction of the IBM PC and numerous related hardware and software products to the consumer market.

He worked for IBM in the United States and the UK from 1955 until 1970.

Application level compatibility ( with some restrictions ) for System / 360 software is maintained until present day with the IBM zSeries computers.

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.

Virtual memory was not available in most IBM mainframes until the System / 370 series.

LLNL is home to many unique facilities and a number of the most powerful computer systems in the world, according to the TOP500 list, including Blue Gene / L, the world's fastest computer from 2004 until Los Alamos National Laboratory's IBM Roadrunner supercomputer surpassed it in 2008.

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.

The state of affairs continued until the 1960s when IBM, already a leading hardware vendor, stopped work on existing systems and put all their effort into developing the System / 360 series of machines, all of which used the same instruction and input / output architecture.

" The upgrade, required to run OS / VS1 or OS / VS2, was not cost effective for most customers by the time IBM could actually deliver and install it, so many customers were stuck with these machines running MVT until their lease ended.

The Justice Department accused IBM of doing this intentionally because the System / 360 Model 91 was not released until three years later.

The resulting architecture was used in various roles in IBM until the 1980s.

* Hardware support for floating-point operations: optional on the original IBM PC ; remained on a separate chip for Intel systems until the 80486DX processor.

Microsoft did not grant IBM OEM rights for Windows 95 until 15 minutes prior to the release of Windows 95, August 24, 1995.

One ( STR, instruction code binary 101 ) was not implemented until the IBM 709.

The project was left in limbo until April 1996 when the product was officially killed, shortly after IBM purchased Lotus.
