The IBM 2922 Programmable Terminal was a Remote Job Entry (RJE) terminal introduced by IBM in 1972. The 2922 communicated using Binary Synchronous Communications (Bisync). The 2922 and associated peripherals were RPQs, that is special-order equipment not on the standard price list. The system was a repackaging of an IBM System/360 Model 20 and peripherals for use as a dedicated terminal. ==Standard components== The 2922-1 Terminal Control Unit (RPQ 810563) employed the same instruction set architecture as the Model 20. It incorporated 8,192 bytes of 3.6 μs magnetic-core memory. The control unit also containd the Binary Synchronous Communications Adapter (BSCA) integrated into the Terminal Control Unit that supported a single line at speeds up to 7200 bits per second (bps). The 2922-2 Terminal Printer (RPQ 810564) was a repackaged 1403 printer. The printer used a print chain and provided a page width of 132 characters using fanfold paper. The controls and indicators for the printer were located on the front panel of the Terminal Control Unit, except for a duplicate ''start'' key on the rear of the printer. The 2922-3 Terminal Card Reader (RPQ 810565) was a repackaged 2501, an optical punched card reader for 80-column cards with a rated speed of 500 cards per minute. The controls and indicators for the card reader were located on the front panel of the Terminal Control Unit. 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 2922」の詳細全文を読む スポンサード リンク
