TIM-600 was an important PC computer system in the TIM series of microcomputers from Mihajlo Pupin Institute-Belgrade, developed from 1987 to 1988.[1][2][3] It was based on the Intel microprocessor types 80386 and 80387. It has word-length of 32 bits, basic cycle time of 20 MHz and operating system Unix V.3.[4][3] The TIM-600 computer system was presented at the Munich International Computer Exhibition in September 1988.
TIM-600 architecture was based on three system buses (32, 16 and 8 bits respectively). The CPU performs 5,000,000 simple operations per second. Primary memory RAM had a maximum capacity of 8 x 2 MB. There were a maximum of eight TIM terminals or other equipment units connected by RS-232C. Centronics types interface was used for the line printers. Also, there were possibilities for the connections of two hard disks as well as the magnetic cassettes and diskettes.
The TIM-600 computer system was used for business data processing in many offices in Serbia, for example in public, health, and scientific organizations; for process automation in industrial production; in road traffic control; in some banks; for military and government services, etc.
