CER ((セルビア語:Цифарски Електронски Рачунар) – ''Digital Electronic Computer'') model 22 was a transistor based computer developed by Mihajlo Pupin Institute (Serbia) in 1967-1968. It was originally intended for banking applications and was used for data processing and management planning in banks, trade and utility companies in Belgrade. Three CER-22 computers were purchased by Beobanka, Jugopetrol and BVK–Belgrade companies. (For more detailles see: Ref.# 1, #2, #3, and #4). The principal designers and chiefs of the project teams were: *Dušan Hristović, Svetomir Ojdanić, Veselin Potić, Radivoje Ilić et al. for Beobanka; *Dr Sc. Miroslav Jocković, Branimir Leposavic, Michael Savikin, Ljubivoje Marković et al., for Jugopetrol co.; *Vladislav Paunović, Miloš Marjanović, Petar Vrbavac, Dragiša Tinković et al. for BVK-Belgrade. ==Technical characteristics of the CER-22== * Technology: IC (MSI), transistor and diode logic circuits (See also: Ref. #2, #5, #6). * Printed circuits boards with the ribbon connectors; * CPU performance: the 16-cycle instructions (10 microseconds); * Magnetic core memory: 32 KB capacity (memory cycle time of 2 microseconds); * Disk storage CDC-854 (max 8 disk units); * Card reader and puncher: 300 cards/min and 150 cards/min; * Paper tape reader and puncher, type "Facit": 1000 characters/s and 150 characters/s; * Parallel Line Printer, type DP MZ-4: 128 characters/line, 600 lines/min. 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「CER-22」の詳細全文を読む スポンサード リンク
