The ibm system 370 (s 370) is a model range of ibm mainframe computers announced on june 30, 1970 as the successors to the system 360 family. the series mostly maintains backward compatibility with the s 360, allowing an easy migration path for customers; this, plus improved performance, were the dominant themes of the product announcement. in september 1990, the system 370 line was replaced. This paper discusses the design considerations for the architectural extensions that distinguish system 370 from system 360. it comments on some experiences with the original objectives for system 360 and on the efforts to achieve them, and it describes the reasons and objectives for extending the architecture. The architecture of ibm’s system 360 370 series of compatible processors is one of the most durable artifacts the computer age. through two major revisions of the product line and 23 years of technological change, it has remained a viable and versatile interface between machine and user. david gifford and alfred spector. Abstract the architecture of ibm's system 360 370 series of compatible processors is one of the most durable artifacts of the computer age. through two major revisions of the product line and 23 years of technological change, it has remained a viable and versatile interface between machine and user. System 370 extended architecture (370 xa). the interpretive execution facility serves the special purpose of improving the efficiency with which a specialized component of a control program can oversee the execution of programs in a virtual machine environ ment.

Ibm's 360 and early 370 systems describes the creation of this remarkable system and the developments it spawned, including its successor, system 370. This publication is intended primarily for use by s 370 assembler language application programmers. it contains basic machine information summarized from the system 370 principles of operation (ga22 7000) about system 370 models 115 through 195; the 3031, 3032, 3033, 3081, 3083, and 3084 processor. The basic idea behind the ibm system 360 was a family of computers that shared the same architecture but had different organization. for example, each of the computers in the family had 16 general purpose 32–bit registers, numbered 0 through 15. these were logical constructs. the organization of the different models called for registers to be.

Hercules is an open source software implementation of the mainframe system 370 and esa 390 architectures, in addition to the new 64 bit z architecture. hercules runs under linux, windows (98, nt, 2000, and xp), solaris, freebsd, and mac os x (10.3 and later). hercules is osi certified open source software licensed under the terms of the q public licence. Today, the strategic ibm mainframe environment is delivered via the ibm enterprise systems architecture 3701 this architecture is the latest in a series of steps that began in the mid 1960's with the introduction of the ibm system 360 architecture. there is little reason to believe that esa 370 is the final step in this evolution. The ibm system 360 architecture is the model independent architecture for the entire s 360 line of mainframe computers, including but not limited to the instruction set architecture.the elements of the architecture are documented in the ibm system 360 principles of operation and the ibm system 360 i o interface channel to control unit original equipment manufacturers' information manuals.

Over the years, as mvs 370 gained more functions and was asked to handle more complex applications, even access to 16 megabytes of virtual storage fell short of user needs. with the release of the system 370 xa architecture in 1983, ibm extended the addressability of the architecture to 31 bits. The ibm system 360 (s 360) is a family of mainframe computer systems that was announced by ibm on april 7, 1964, and delivered between 1965 and 1978. it was the first family of computers designed to cover the complete range of applications, from small to large, both commercial and scientific. Release 4 is based on ibm system 370 extended architecture (370 xa) and completely replaces release 3. it supports system 370 xa processors, 3990 storage controllers, and 3380 direct access storage devices (dasd). reliability is increased through simplification of 370 xa input output (xa i o) initiation. tightly coupled supports. It means that your pc can emulate an ibm mainframe processor. the mainframe can range from a system 360 to a z10 running in "s 370" mode, "esa 390" mode, or "z architecture" mode. hercules executes s 370, esa 390, and z architecture instructions and channel programs. it emulates mainframe i o devices by using pc devices.
