In Japan, it was introduced in 1983 and promoted as "Multistation 5550" because it had three roles in one machine: a PC, a word processing machine which was traditionally marketed as a machine different from a PC in Japan, and an IBM-host attached terminal. GeneralThe IBM PC that had been marketed by IBM since 1981, using Intel 8088, was not powerful enough to process the far eastern languages of Japanese, Korean and Chinese. Nor was the resolution of IBM PC's display high enough to show the complex characters of these languages. The IBM 5550 was first introduced in Japan in March 1983,[1] using Intel 8086 microprocessor and was called "Multistation 5550" because it had three roles in one machine: a PC, a word processing machine which was traditionally marketed in Japan as a machine different from a PC, and an online terminal. After the Japanese 5550 models, Korean, Traditional Chinese and Simplified Chinese models were also introduced. IBM 5550 initially used its own architecture, but, later since 1987, was changed to use IBM Personal System/2's Micro Channel Architecture, being renamed as Personal System/55. In Japan, Kiyoshi Atsumi, a film actor, was used to promote the 5550. IBM later introduced IBM JX for home users in Japan, Australia and New Zealand, and DOS/V for both business and home users in Japan. FeaturesIBM 5550's features are:

ReceptionBYTE in 1983 speculated that "we may soon see a similar machine here in America". Describing the 5550 as "a true workstation", the magazine envisioned the computer as filling the "considerable gulf above the PC", and a rival to the IBM System/36 minicomputer. It praised the 5550's "unprecedented" combination of kanji support with high-end word-processing capability, and reported that in Japan an ecosystem of vendors providing products for the computer was forming. The magazine concluded that "if the American PC is any precedent, the market should soon be filled with 5550 software".[2]See also
