Hercules is a computer emulator allowing software written for IBM mainframe computers (System/370, System/390, and zSeries/System z) and for plug compatible mainframes (such as Amdahl machines) to run on other types of computer hardware, notably on low-cost personal computers. Development started in 1999 by Roger Bowler, a mainframe systems ...
The typical ordering process of modern IBM Z mainframe looks like a buying of service [50] or looks like a leasing; [51] the mainframe is a program/hardware complex with rent for a system workload, and (in the most cases) additional system capabilities can be unlocked after additional payment.
The primary operating systems in use on current IBM mainframes include z/OS (which followed MVS/ESA and OS/390 in the OS/360 lineage), z/VM (which followed VM/ESA and VM/XA SP in the CP-40 lineage), z/VSE (which is in the DOS/360 lineage), z/TPF (a successor of Transaction Processing Facility in the Airlines Control Program lineage), and Linux ...
[6] [7] In February 2005, IBM announced z/VSE as successor to VSE/ESA 2.7, which was named to reflect the new System z branding for IBM's mainframe product line. [8] [9] In June 2021, 21st Century Software Inc announced that it had licensed the z/VSE source code from IBM with the intention of developing new versions of the operating system. [10]
An IBM System Z10 mainframe computer on which z/OS can run. z/OS is a 64-bit operating system for IBM z/Architecture mainframes, introduced by IBM in October 2000. [2] It derives from and is the successor to OS/390, which in turn was preceded by a string of MVS versions.
Many of the early users of PCs were mainframe programmers or users, who were accustomed to and liked the ISPF panel system. This led several companies to create partial clones of ISPF that run on DOS, OS/2, Windows or Unix PC systems. In 1984 IBM introduced the EZ-VU dialog manager for DOS PCs, [13] [14] and later OS/2.

The project was announced on August 17, 2015, and was driven by IBM, a major supplier of mainframe hardware, as well as 16 other founding members, that included SUSE, CA Technologies, BMC Software, Compuware as well as clients and partners such as RSM Partner, Vicom Infinity, L3C LLP and ADP, and academic institutions such as Marist College and ...
