With the advent of the latest generation of IBM mainframes – the z16 – Big Blue is furthering one of the most successful technology systems the IT world has known. Here are a few key moments in the history of the Big Iron:
In 1964 IBM began what many would consider the first true series of mainframes, the IBM 360. At the time IBM said its central processors included 19 combinations of graduated speed and memory capacity. The system also included more than 40 types of peripheral equipment for entering, storing, and retrieving information. Built-in communications capability made the System/360 available to remote terminals, regardless of distance.
