| dbo:abstract |
270x is a generic name for a family of IBM non-programmable communications controllers used with System/360 and System/370 computers. The family consisted of the following devices: * IBM 2701 Data Adapter Unit * IBM 2702 Transmission Control * IBM 2703 Transmission Control The 2701 and 2702 were announced simultaneously with System/360 in 1964, the 2703 was announced a year later. The 270x series was superseded by the IBM 3704 and 3705 communications controllers in 1972. (en) IBM 270x（IBMにぃななまるエックス、英語: IBM 270x）はIBMが1964年に発表したSystem/360の中で、遠隔地の端末機をモデム・通信回線を通して接続するための周辺機器で、IBM 2701/2702と翌年に発表したIBM 2703があった。IBM 270xは後に、IBM 370x通信制御装置（IBM 3704/3705 Communications Controller）に置き換えられていった。 (ja) |
