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 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 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.
