Lançamento do IBM System/360

       Lançamento do IBM System/360  

The IBM System/360 (S/360) is a mainframe computer system family announced by IBM on April 7, 1964. It was the first family of computers designed to cover the full range of applications, from small to large, both commercial and scientific.

The design made a clear distinction between architecture and implementation, allowing IBM to release a suite of compatible designs at different price points. All but the highest-end systems used microcode to implement the instruction set, which featured 8-bit byte addressing and binary, decimal and floating-point calculations. 


The System/360 models announced in 1964 ranged in speed from 0.034 MIPS to 50 times that speed, with 8 kB and up to of 8 MB main memory, though the latter was unusual. A large system might have 256 KB of main storage. The 360s were extremely successful in the market, allowing customers to purchase a smaller system with the knowledge they would always be able to migrate upward if their needs grew. 

The design is considered by many to be one of the most successful computers in history, influencing computer design for years to come. The chief architect of the S/360 was Gene Amdahl, and the project was managed by Fred Brooks, under Chairman Thomas J. Watson Jr.


"In the most important product announcement in company history to date, IBM introduces the IBM System/360, a new concept in computers which creates a family of small to large computers incorporating IBM-designed Solid Logic Technology (SLT) microeletronics and uses the same programming instructions. 
The concept of a compatible family of computers transforms the industry. "
