The IBM 8000 series was a proposed transistor-based successor to the IBM 7000 series. Important engineers on the project included Fred Brooks and Gerry Blaauw. The project plan for the 8000 series was presented by Fred Brooks in January, 1961. Despite some technical successes, the project became a political football, amid IBM's search for a unified product line. The project was canceled in 1961 by Bob Evans, supplanted by the very successful System/360 series. The 8000 project may have seen the first use of the term "architecture" in relation to computers. ==Problems== Pugh cites a number of reasons for the cancellation of the 8000 line.〔 * Because more integrated technology was not yet available the system was to have been built using ''discrete transistor'' (SMS) components. * The proposed systems would have been incompatible with IBM's existing successful 1400 series systems. * The proposed instruction set was too complex. * The systems offered inadequate floating point performance, bolstered only by add-on processors. 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 8000」の詳細全文を読む スポンサード リンク
