Gerstner, Jr. began his remarkable career at IBM as Lacking vision and clinging to their mainframe mentality, they missed out on the first once again, just like in its earlier halcyon days of the 1960s and 1970s.

It was the first family of computers designed to cover the complete range of applications, from small to large, both commercial and scientific. IBM's current mainframe operating systems, z/OS, z/VM, z/VSE, and z/TPF, are backward compatible successors to operating systems introduced in the 1960s, although of course they have been improved in many ways. Both IBM-supplied operating systems and those supplied by others are discussed here if notably used on IBM mainframes.

It was the second generation after the 709 vacuum tube mainframe computers. The 7090 was six times faster than the 709 thanks to the use of more than 50,000 transistors and magnetic core storage, but it took up considerably less floor space and required less power and air conditioning.

The power of compatibility was demonstrated in the fall of 1960, when IBM introduced the more powerful 1410 to replace the 1401. Software and peripheral equipment for the 1401 worked with the
IBM's iconic mainframe turns 50: In its history the IBM mainframe has been hailed and vilified. It has been born, reborn (many times) and pronounced dead. And yet the Big Iron remains a key computing resource for many large companies and will do so for many years. Here we take a look at the mainframe’s long history, from its use with the US space program to its prominence inside large

Qui-binary arithmetic: how a 1960s IBM mainframe does math The IBM 1401 computer uses an unusual technique called qui-binary arithmetic to perform arithmetic. In the early 1960s, the IBM 1401 was the most popular computer, used by many businesses for the low monthly price of $2500. Gene Amdahl. In 1960, IBM’s Gene Amdahl was named manager of architecture for their new System/360 family of mainframe computers. Amdahl’s challenge was to design a family of computers that would support a range of speeds and peripherals yet run the same software. 2020-01-09
