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.
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.

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.

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 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.
