# CER Computer

CER (Serbo-Croatian Latin: Cifarski Elektronski Računar, lit. 'Digital Electronic Computer') was a series of early computers (based on vacuum tubes and transistors) developed by Mihajlo Pupin Institute in Yugoslavia in the 1960s and 1970s.
Models:
* CER-10 - 1960, based on vacuum tubes, transistors, electronic relays, and magnetic core memory. First Yugoslav digital computer (developed in "Vinca"-Institute) in (SFRY).
* CER-2 - 1963, a prototype model
* CER-20 - 1964, CER-30 - 1966, - the prototypes of the "electronic bookkeeping machine" for EI Niš and RIZ Zagreb;.
* CER-200 - 1966, series of 18 "electronic bookkeeping computers".
* CER-202-1968; CER-203 - 1972
* CER-22 - 1967, based on transistors, MSI circuits, magnetic core memory, punched cards and magnetic disks. Serie of 3 electronic systems, used for on-line banking operations and data processing applications;
* CER-12 - 1971, "electronic computer for business data processing", based on VLSI technology, wire wrapping boards, magnetic disks and magnetic tapes;
* CER-11 - 1966, based on transistors, core memory, Teletype printer etc. Mobile military computer (used in the JNA (Yugoslav People's Army);
* CER-101 Kosmos - 1973, based on VLSI circuits, core memory, magnetic drum, paper tapes, Teletype printers; Mobile computer in special military vehicles (used in the JNA's V.T. Institute);
* CER-111 - 1975, Mobile military computer, based on VLSI technology, Hard disk drive; Used in JNA until 1989.
