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 introduced its System / 360 family of computers in the mid-1960s, it did not provide a solution for this limitation and within IBM there were conflicting views about the importance of and need to support time-sharing.

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

When fully implemented, CAIR will reduce SO < sub > 2 </ sub > emissions in 28 eastern states and the District of Columbia by over 70 percent and NOx emissions by over 60 percent from 2003 levels.

When the processors and their interconnect are all implemented on a single silicon chip, the technology is known as a multi-core microprocessor.

When General Kolingba became president in 1981, he implemented an ethnicity-based recruitment policy for the administration.

When these revolutionary changes to the Church were implemented, it spawned a counter-revolutionary movement, particularly amongst women.

When properly implemented, as in the Columbia University Kermit Software collection, Columbia University's Kermit group claim performance is equal to or better than other protocols such as ZMODEM, YMODEM, and XMODEM, especially on poor connections.

When this compiler was ported to the VAX platform, a common backend for Mary and CHILL was implemented.

When the concept of assured destruction is applied in the doctrine of law, it is often criticized by proponents of the restorative justice and transformative justice approaches, who point out that assured destruction doctrines are rarely implemented with rigor or integrity of due process.

When implemented as impact printers, they can be the least expensive to operate per page.

When implemented with relays and other electromechanical devices, the various rules " execute " simultaneously and immediately.

When implemented in a programmable logic controller, the rules are typically executed sequentially by software, in a continuous loop ( scan ).

When implemented appropriately, it can help people change their cognitive processes, which may then correspond with changes in their feelings and behaviours.

When the new Duke Victor Amadeus I was forced to accept a French occupation of Pinerolo ( Peace of Cherasco, 26 April 1631, and associated secret agreements, implemented 1632 ), there was widespread dissatisfaction in Piedmont, and Thomas, with his brother Maurice, went to join the Spanish, at which Victor Amadeus confiscated their revenues.

When Richard of Staughton became prior, he obtained permission from the bishop to form a boys ' school ; however it is thought he died of the Black Death before the project could be implemented.

When Kyrgyzstan became independent following the Soviet Union's collapse in 1991, there was a popular idea among some Kyrgyz people to make transition to the Latin alphabet ( taking in mind a version closer to the Turkish alphabet, not the original alphabet of 1928 – 1940 ), but the plan was never implemented.

: When implemented, enables the transfer of data, and notification of data changes.

When implemented it allows the object to draw drag-and-drop effects, and to specify when the object is dropped, or the drag-and-drop operation is cancelled.

When implemented it allows the target to specify if a dropped object will be accepted, and what happens to an object after it is dropped.

When the first local government acts were implemented in Sweden in 1863 Dorotea parish was made a rural municipality.

When EPS was first implemented, the only machines widely using PostScript were Apple Macintoshes.

When implemented using a cardioid-patterned microphone, it emphasizes low-frequency sounds in the voice due to a cardioid microphone's proximity effect and can give a more relaxed feel because the performer isn't working so hard.

When first implemented, the rule change did not apply to companies with one or two letter symbols, but subsequently any stock was able to move from the NYSE to the Nasdaq without changing its symbol.

When the buffer consumption rate exceeds some critical value ( roughly: the rate where all of the buffer may be expected to be consumed before the end of the project, resulting in late completion ), then those alternative plans need to be implemented.

* When less than 20 percent of children have symptoms, mass treatment is not implemented.
