IBM 5550 is a personal computer series that IBM marketed in Japan, Korea, Taiwan and China in the 1980s and 1990s, for business use customers. In Japan, it was introduced in 1983 and promoted as "Multistation 5550 (マルチステーション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.
