The System/38 [2] [3] is a discontinued minicomputer and midrange computer manufactured and sold by IBM.The system was announced in 1978. [4] The System/38 has 48-bit addressing, which was unique for the time, and a novel integrated database system.
The original IBM Personal Computer, with monitor and keyboard. 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.
Products, services, and subsidiaries have been offered from International Business Machines (IBM) Corporation and its predecessor corporations since the 1890s. [1] This list comprises those offerings and is eclectic; it includes, for example, the AN/FSQ-7, which was not a product in the sense of offered for sale, but was a product in the sense of manufactured—produced by the labor of IBM.
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]
System/32 (introduced in 1975) [5] was a 16-bit single-user system also known as the IBM 5320. System/34 (1977) was intended to be a successor to both the 3 and the 32. System/38 (1979) was the first midrange system to have an integrated relational database management system (DBMS). The S/38 had 48-bit addressing, and ran the CPF operating system.
The XPF also contains the System/36 Environment and System/38 Environment, which provide backwards compatibility APIs and utilities for applications and data migrated from SSP and CPF systems. [42] The XPF is IBM's internal name for this layer, and as the name suggests, began as an evolution of the System/38 Control Program Facility. [1]

The IBM System/38 operating system, which introduced many advanced concepts, lives on with IBM's AS/400. Great efforts were made by IBM to enable programs originally written for the IBM System/34 and System/36 to be moved to the AS/400. After being rebranded multiple times, the AS/400 platform was replaced by IBM Power Systems running IBM i.
