IBM PS/2 Note

The Personal System/2 or PS/2 was IBM's third generation of personal computers released in 1987. The PS/2 line was created by IBM in an attempt to recapture control of the PC market by introducing an advanced yet proprietary architecture. IBM's considerable market presence plus the reliability of the PS/2 ensured that the systems would sell in relatively large numbers, especially to large businesses. However the other major manufacturers balked at IBM's licensing terms to develop and sell compatible hardware, particularly as the demanded royalties were on a per machine basis. Also the evolving Wintel architecture was seeing a period of dramatic reductions in price, and so these developments prevented the PS/2 from returning control of the PC market to IBM.

The N33 was IBM's first notebook-format computer from year 1991, Model 8533, 386SX)

It was originally a machine developed by IBM Japan for domestic markets. After the arch-rival Compaq brought the E-Lite 386 laptop series IBM was forced to bring out a counter-product.
