High Quality Content by WIKIPEDIA articles! Wang 2200, appeared in May 1973, was Wang Laboratories` first minicomputer that could perform data processing in a common computer language. Unlike some other desktop computers, such as the HP 9830, it had a cathode ray tube (CRT) in a cabinet that also included an integrated computer controlled cassette tape storage unit and keyboard. Microcoded to run interpretive BASIC, about 65,000 systems were shipped in its lifetime and it found wide use in small and medium-size businesses worldwide. The 2200 evolved into a desktop computer and larger system to support up to 16 workstations and utilized commercial disk technologies that appeared in the late 1970s and early 1980s. The disk subsystems could be attached to up to 15 computers giving a theoretical upper limit of 240 workstations in a single cluster.
