System/360 Model 91 in the late 1960s. We're seeing industry pundits from all quarters take the time to congratulate or castigate IBM for being able to sell variations of the System/360 for 50 years.

The System/360 and its successor System/370 continued to sell well into the 1970s, as punch cards were slowly replaced by IBM 3270 terminals, known as green screens.

Before the advent of the mainframe, IBM developed the 350 RAMAC. Built in 1956, it used a stack of fifty 24-inch disks as memory, which held about 4.4MB of data—just enough to store two pictures.

IBM made a big bet in when it released the System/360 family of mainframes in 1964. They're not exactly IBM's biggest hit today, but they did help computing move forward, toward interoperability.

You can check it out in the video below. The internals were based somewhat on the IBM System/360’s technology. Interestingly, it used a touch-sensitive keypad instead of a traditional keyboard.

It was developed at IBM Hursley in the UK and used magnetic core memory. It used BCD for numerical display instead of hexadecimal or octal, with floating point numbers as a basic type.

Fifty years ago on April 7, IBM announced the computer that the task force had designed, the System/360. The system eventually became a huge success for the company — and a good thing too.
