WHY PS/2?
IBM’s first family of Personal Computers of 1981 to 1988, allowed for non-IBM vendors to “clone” the IBM technology to produce their own lines of PCs which were essentially IBM compatible. This helped grow the early PC market, but IBM lost sales to lower prices clones during this time period.
IBM believed that to help it recapture some of the PC market, a proprietary technology was needed. IBM developed "Micro Channel Architecture" (MCA), and incorporated it into most of their new PS/2 machines. MCA was a proprietary BUS technology that could not be legally cloned. In some respects, it was more advanced than the existing IBM “ISA” BUS.
The PS/2 family was designed to promote the MCA BUS and get it into the marketplace on a wide scale. The plan also included supplying IBM's OS/2 operating system for the new machines as well as other software products. This plan resulted in many corporate sales, however, it was not successful in helping IBM recapture a large share of the PC market.

There were numerous models of the PS/2 line as well as numerous form factors. The Model 70 was introduced in 1989. Higher end machines were also available, such as the PS/2 model 90 XP 486, introduced in 1990.

Depending on its configuration, the PS/2 Model 70 386 originally sold for over $7,000 (or over $15,000 in 2021 dollars), making it very pricey for home PC users.

The PS/2 line was discontinued in the mid 1990's.

In 2005, IBM sold its personal computer business to Lenovo, but retained a partial ownership in that company.
