IBM System 360/195 Computer
The IBM System/360 (S/360) is a family of mainframe computer systems that was announced by IBM in April 1964, and delivered between 1965 and 1978. It was the first family of computers designed to cover both commercial and scientific applications and a complete range of applications from small to large. The design distinguished between architecture and implementation, allowing IBM to release a suite of compatible designs at different prices.
The slowest System/360 model announced in 1964, the Model 30, could perform up to 34,500 instructions per second, with memory from 8 to 64 KB. High-performance models came later. The 1967 IBM System/360 Model 91 could execute up to 16.6 million instructions per second. The larger 360 models could have up to 8 MB of main memory, though that much memory was unusual; a large installation might have as little as 256 KB of main storage, but 512 KB, 768 KB or 1024 KB was more common. Up to 8 megabytes of slower (8 microsecond) Large Capacity Storage (LCS) was also available for some models.
The IBM 360/195 computer was introduced in 1971. It comprised six parts: operating console, two modules of ferrite core, two high-speed buffers, power supply, logic board, and sample co-axial wiring
An IBM 360/195 at the University of California, Santa Barbara was one of the first computers to be connected to the ARPANET, the first computer network which used packet switching to share information between disparate computers. In 1969 the fledgling network consisted of just four nodes, all on the West Coast of the United States. An IBM 360/195 was used at University College London to connect the UK's Rutherford High-Energy Laboratory to the expanding ARPANET in 1973. This example, seen behind glass, was donated to the Science Museum by the Meteorological Office at Bracknell in 1983.
