The IBM 1130 Computing System, introduced in 1965, was IBM's least expensive computer at that time. It was aimed at price-sensitive, computing-intensive technical markets like education and engineering, succeeding the IBM 1620 in that market segment. The 1130 was also used as an intelligent front-end for attaching an IBM 2250 Graphics Display Unit, or as remote job entry (RJE) workstation, connected to a System/360 mainframe. ==Description== The total production run of the 1130 has been estimated at 10,000.〔 〕 The 1130 holds a place in computing history because it (and its non-IBM clones) gave many people their first direct interaction with a computer. Its price-performance ratio was good and it notably included inexpensive, removable disk storage, with reliable, easy-to-use software that supported several high-level languages. The low price (from around $32,000 or $41,000 with disk drive) and well-balanced feature set enabled interactive "open shop" program development. The IBM 1130 used the same electronics packaging, called Solid Logic Technology (SLT), used in System/360. It had a 16-bit binary architecture, as did later minicomputers like the PDP-11 and Data General Nova. The address space was 15 bits, limiting the 1130 to words () of memory. The 1130 used magnetic-core memory, which the processor addressed on word boundaries, using direct, indirect, and indexed addressing modes. 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 1130」の詳細全文を読む スポンサード リンク
