IBM Introduces the System/360 Family of Computers

On April 7, 1964 IBM announced the System/360 family of compatible machines.  All IBM System/360 products ran the same operating system—OS/360. Previously products developed by different divisions of IBM were incompatible.

IBM System/360 products were the first IBM computers capable of both commercial and scientific applications that were offered at what was then considered a “reasonable price.” Their architecture incorporated microprogramming.
