The IBM Personal Computer, commonly known as the IBM PC, spanned multiple models in its first generation (including the PCjr, the Portable PC, the XT, the AT, the Convertible, and the /370 systems, among others), from 1981 to 1987. It eventually gave way to many splintering product lines after IBM introduced the Personal System/2 in April 1987.
Control Program Facility (CPF) is the operating system of the IBM System/38. [3] CPF represented an independendent line of development at IBM Rochester, and was unrelated to the earlier and more widely used System Support Program operating system. CPF evolved into the OS/400 operating system, which was originally known as XPF (Extended CPF). [1]
In 1980 IBM changed its name to System Productivity Facility [6] and offered a version [7] for CMS under VM/SP. [ 8 ] In 1982 IBM changed the name to Interactive System Productivity Facility, [ 9 ] split off some facilities into Interactive System Productivity Facility/Program Development Facility (ISPF/PDF) and offered a version for VSE/AF .
IBM System/3 BASIC was an interpreter for the BASIC programming language for the IBM System/34 midrange computer. [1]System/34 BASIC was first offered in 1978, and as such, contained many of the trappings that a BASIC program would have encountered in the time period of the TRS-80, or many other offerings of the 1970s and early 1980s.

Screen Design Aid (SDA) is a utility for the IBM System/34 and System/36 midrange computers. Programmers can use SDA to create menus, display formats, or WSU skeleton programs. The System/38, and IBM i platforms also have a utility Screen Design Aid, but its syntax and functionality are different.
Using SSP, the operator can create, delete, and manage S/34-36 objects such as libraries, data files, menus, procedures, source members, and security files. SSP contains modules such as DFU, SEU, SDA, and WSU that permit operators to build libraries and files, enter information into those files, produce simple reports, and maintain a menu structure that simplifies access to the information.
The IBM System/360 Model 20 is the smallest member of the IBM System/360 family announced in November 1964. The Model 20 supports only a subset of the System/360 instruction set, with binary numbers limited to 16 bits and no floating point arithmetic . [ 1 ]
Non-IBM SNA software allowed systems other than IBM's to communicate with IBM's mainframes and AS/400 midrange computers using the SNA protocols. Some Unix system vendors, such as Sun Microsystems with its SunLink SNA product line, including PU2.1 Server, [ 31 ] and Hewlett-Packard / Hewlett Packard Enterprise , with their SNAplus2 product ...
