CER (Serbian: Цифарски Електронски Рачунар – Digital Electronic Computer) model 22 was a transistor based computer developed by Mihajlo Pupin Institute (Serbia) in 1967. 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.

The principal designers and chiefs of the project teams were:

• Dušan Hristović, Svetomir Ojdanić, Ljubivoje Marković, Veselin Potić, Radivoje Ilić et al. for Beobanka;
• Dr Sc.Miroslav Jocković, Michael Savikin,Vladan Pavlović, Veselin Potić, Branimir Leposavić 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;
• Printed circuits boards with the ribbon connectors;
• CPU performance: the 16-cycle instructions (10 microseconds);
• Magnetic core memory: 32 KB capacity (cycle time of 2 microseconds);
• Disk storage CDC-854 (max 8 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.
