2. Hercules (emulator) - Wikipedia

   en.wikipedia.org/wiki/Hercules_(emulator)

   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 ...

3. PC-based IBM mainframe-compatible systems - Wikipedia

   en.wikipedia.org/wiki/PC-based_IBM_mainframe...

   Since the rise of the personal computer in the 1980s, IBM and other vendors have created PC-based IBM mainframe-compatible systems which are compatible with the larger IBM mainframe computers. For a period of time PC-based mainframe-compatible systems had a lower price and did not require as much electricity or floor space.

4. VM (operating system) - Wikipedia

   en.wikipedia.org/wiki/VM_(operating_system)

   When IBM introduced the P/370 and P/390 processor cards, a PC could now run full VM systems, including VM/370, VM/SP, VM/XA, and VM/ESA (these cards were fully compatible with S/370 and S/390 mainframes, and could run any S/370 operating system from the 31-bit era, e.g., MVS/ESA, VSE/ESA).

5. MVS - Wikipedia

   en.wikipedia.org/wiki/MVS

   When IBM introduced its 64-bit z/Architecture mainframes in the year 2000, IBM also introduced the 64-bit z/OS operating system, the direct successor to OS/390 and MVS. Fujitsu and Hitachi opted not to license IBM's z/Architecture for their quasi-MVS operating systems and hardware systems, and so MSP and VOS3, while still nominally supported by ...

6. OS/390 - Wikipedia

   en.wikipedia.org/wiki/OS/390

   IBM Communications Server – Provides Virtual Telecommunications Access Method (VTAM) and TCP/IP communications protocols An additional benefit of the OS/390 packaging concept was to improve reliability, availability and serviceability (RAS) for the operating system, as the number of different combinations of elements that a customer could ...

7. ISPF - Wikipedia

   en.wikipedia.org/wiki/ISPF

   In computing, Interactive System Productivity Facility (ISPF) [1] is a software product for many historic IBM mainframe operating systems and currently the z/OS and z/VM operating systems that run on IBM mainframes.

8. z/OS - Wikipedia

   en.wikipedia.org/wiki/Z/OS

   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.

9. IBM Basic assembly language and successors - Wikipedia

   en.wikipedia.org/wiki/IBM_Basic_assembly...

   The application program interfaces of IBM's mainframe operating systems is defined as a set of assembly language "macro" instructions, that typically invoke Supervisor Call (SVC) [e.g., on z/OS] or Diagnose (DIAG) [on, e.g., z/VM] instructions to invoke operating system routines. It is possible to use operating system services from programs ...
