  CER (Serbian: Цифарски Електронски Рачунар – Digital Electronic Computer) model 22 is 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 details 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.
