When Compaq introduced the first PC based on Intel's new 80386 microprocessor, the Compaq Deskpro 386, in 1986, it marked the first CPU change to the PC platform that was not initiated by IBM.

When the IBM PC was introduced, IBM sold its operating system as an unbundled ( but necessary ) option.

When the PC was introduced in 1981, it was designated as the IBM 5150, putting it in the " 5100 " series, though its architecture was not directly descended from the IBM 5100.

When one of these keys is pressed, it will cause its control unit, historically, an 3174 or IBM 3274 but later the mainframe integrated communications adapter, to generate an I / O interrupt and present a special code identifying which key was pressed.

When IBM later expanded the S / 370 address space in S / 370-XA, several reasons are cited for the choice of 31 bits:

When IBM announced its Professional Workstation computer in 1986, they noted the lack of third-party programs written for it at the time, signaling those developers to start preparing.

When IBM used the 80286 in their IBM Personal Computer AT, they solved this problem by including a software-settable gate to enable or disable ( force to zero ) the A20 address line, between the A20 pin on the 80286 and the system bus ; this is known as Gate-A20 ( the A20 gate ), and it is still implemented in PC chipsets to this day.

When Microsoft entered an agreement with IBM to develop OS / 2, it lost interest in promoting Xenix.

When the IBM Personal Computer was being developed, DR was asked to supply a version of CP / M written for the Intel 8086 microprocessor as the standard operating system for the PC, which used the code-compatible Intel 8088 chip.

When the IBM PC arrived in late 1981, it came with PC-DOS, which was developed from 86-DOS, which Microsoft acquired for this purpose.

When the LOAD button on the IBM 1402 Card Read-Punch was pressed, a card was read into memory locations 001-080, a word mark was set in location 001, the word marks in locations 002-080 were cleared, and execution started with the instruction at location 001.

When IBM released its first relational database product, they wanted to have a commercial-quality sublanguage as well, so it overhauled SEQUEL and renamed the basically new language ( System Query Language ) SQL to differentiate it from SEQUEL.

When Informix Corporation acquired Illustra and made their database engine an object-SQL DBMS by introducing their Universal Server, both Oracle and IBM followed suit by changing their database engines to be capable of object-relational extensions.

When IBM contacted other companies to obtain components for the IBM PC, the as-yet unreleased CP / M-86 was its first choice for an operating system because CP / M had the most applications at the time.

When the German astronaut team was merged into a European Space Agency, he did not transfer, but resigned to work at IBM Germany.

When Digital Research founder Gary Kildall examined PC DOS and found that it duplicated CP / M's programming interface, he wanted to sue IBM, which at the time claimed that PC DOS was its own product.

When IBM implemented the parallel interface on the IBM PC, they used the DB25F connector at the PC-end of the interface, creating the now familiar parallel cable with a DB25M at one end and a 36 pin micro ribbon connector at the other.

: When IBM bought Sequent, ... it lacked the size and resources to compete with Sun and Hewlett-Packard Co. in the Unix server market ....

When Littlepage was introduced, if the General behaved as usual, the newcomer faced a staccato salvo of queries: origin??

The monochrome combinations still existing in the 1950s are standardized by the International Telecommunication Union ( ITU ) as capital letters A through N. When color television was introduced, the hue and saturation information was added to the monochrome signals in a way that black & white televisions ignore.

When an APAF-1 gene trap is introduced into cells, many morphological changes occur, such as spina bifida, the persistence of interdigital webs, and open brain.

When twenty-one was introduced in the United States, gambling houses offered bonus payouts to stimulate players ' interest.

When Saint Paul returned to Jerusalem after his conversion, Barnabas took him and introduced him to the apostles ( 9: 27 ).

When benzodiazepines were first introduced, they were enthusiastically adopted for treating all forms of epilepsy.

When Data General introduced the Data General Nova, a company called Digidyne wanted to use its RDOS operating system on its own hardware clone.

When introduced into the human body, curium accumulates in the bones, lungs and liver, where it promotes cancer.

When this was introduced in July 1947, it led to a currency crisis and convertibility had to be suspended after just five weeks.

When the Shang were overthrown by the Zhou, a new political, religious and philosophical concept was introduced called the " Mandate of Heaven ".

When a user with a low bitrate codec talks to a user with another codec, additional distortion is introduced by each transcoding.

When he published his memoirs he introduced the term caldera into the geological vocabulary.

When DEC introduced the PDP-1, they also mentioned larger machines at 24, 30 and 36-bits, based on the same design.

When the Flip Chip packaging allowed the PDP-6 to be re-implemented at a much lower cost, DEC took the opportunity to carry out a similar evolution of their 36-bit design and introduced the PDP-10 in 1968.

When hammerless designs started to become common, the O / U design was introduced, and most modern sporting doubles are O / U designs.

When in the 17th century Gustav II Adolf introduced dragoons into the Swedish Army, he provided them with a sabre, an axe and a matchlock musket, utilizing them as " labourers on horseback ".

When he broadcast on Welsh BBC, early in his career, he was introduced using this pronunciation.

" When he first introduced this concept as a diagnostic entity in the fourth German edition of his Lehrbuch der Psychiatrie in 1893, it was placed among the degenerative disorders alongside, but separate from, catatonia and dementia paranoides.

When using many effects, unwanted noise and hum can be introduced into the sound.

When the 4GL was first introduced, a disparate mix of hardware and operating systems mandated custom application development support that was specific to the system in order to ensure sales.

When Babrius set down fables from the Aesopica in verse for a Hellenistic Prince " Alexander ," he expressly stated at the head of Book II that this type of " myth " that Aesop had introduced to the " sons of the Hellenes " had been an invention of " Syrians " from the time of " Ninos " ( personifying Nineveh to Greeks ) and Belos (" ruler ").
