IBM maintained full compatibility with the past, so that programs developed in the sixties can still run under z / VSE ( if developed for DOS / 360 ) or z / OS ( if developed for MFT or MVT ) with no change.

" 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.

In computing, Time Sharing Option ( TSO ) is an interactive time-sharing environment for IBM mainframe operating systems, including OS / 360 MVT, OS / VS2 ( SVS ), MVS, OS / 390, and z / OS.

The name " Time Sharing Option " derives from the fact that, when it was originally introduced in 1971, IBM considered time-sharing an " optional feature ," as compared to standard batch processing, and hence offered TSO as an option for OS / 360 MVT.

Initially released on IBM mainframe systems using DOS / 360, OS / MFT or OS / MVT, ADABAS is now available on a range of other systems including OpenVMS, Unix ( including Linux and Linux on zSeries ), and Microsoft Windows servers.

It was originally developed in SNOBOL at Bell Labs in 1972 by Marc J. Rochkind for an IBM System / 370 computer running OS / 360 MVT.

In the book PC 97 Hardware Design Guide, Microsoft deprecated support for the RS-232 compatible serial port of the original IBM PC design.

The IBM 1710 was a process control system that IBM introduced in March 1961.

Completely rewritten from the ground up, DOS 2. 0 added subdirectories and hard disk support for the new IBM XT, which debuted in March 1983.

The 1720 led to the IBM 1710 Process Control systems that IBM introduced in March 1961 ; these were cheaper and less elaborate than the 1720.

With the overall home-computer market in decline — even while IBM could not meet the demand for its new PC AT business microcomputer — and likely unable to make a sufficient profit when the PCjr was sufficiently discounted to increase sales, the company discontinued it in March 1985 and, reportedly with more than 100, 000 leftover PCjrs, sold them at a large discount to its employees.

In March 1999, several thousand IBM Aptivas shipped with the CIH virus, just one month before the virus would trigger.
