The IBM 9370 systems were "baby mainframe" midrange computers,〔(October 8, 1986 NY Times article ) stating "to revive its offerings in the midrange computer market"〕 released 1986 at the very low end of, and compatible with System/370. ==Summary== The announcement〔(IBM 9370 INFORMATION SYSTEM OVERVIEW )〕 described the IBM 9370 as "super-mini computer" for commercial and engineering/scientific use—compact, rack-mounted, designed for an office environment, not needing a data center to be used. At the time of announcement the systems were positioned between the IBM System/36 / IBM System/38 and the IBM 4300 series in performance.〔Network World article Dec.22, 1986 p.28〕 Intended to be sold in large amounts as departmental machines ("VAX killers"),〔(Chicago Tribune article )〕 the 9370 initially suffered from lack of software and the failure of IBM to market it properly. Nevertheless, the systems were popular at least with users actually ''needing'' System/370 compatibility while not wanting to accept the expense of a larger system (like e.g. smaller software houses) or with users (like some large IBM customers) preferring hierarchically structured distributed processing solutions rigidly managed by central communication controllers like IBM 37xx. By 1990 the 9370 line had around 6,300 installed systems and generated over 2 billion dollars in sales for IBM.〔 While becoming part of the Enterprise Systems Architecture in 1988 ("ES/9370" like "ES/4300" and "ES/3090"), the 9370s weren't XA systems. In 1990 IBM announced the "ES/9000" series; the rack-mounted models 120-170 with 31-bit ''Enterprise Systems Architecture'' (ESA) and ESCON were the suggested upgrades for ES/9370 users. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「IBM 9370」の詳細全文を読む スポンサード リンク
