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. CPF evolved into the OS/400 operating system, which was originally known as XPF (Extended CPF). [1]
The dedicated hardware platform was replaced in 2008 by the IBM Power Systems platform running the IBM i operating system. Besides System/38 and the AS/400, which inherited much of the FS architecture, bits and pieces of Future Systems technology were incorporated in the following parts of IBM's product line:
It was originally released in 1988 as OS/400, as the sole operating system of the IBM AS/400 line of systems. It was renamed to i5/OS in 2004, before being renamed a second time to IBM i in 2008. [8] [9] It is an evolution of the System/38 CPF operating system, [5] with compatibility layers for System/36 SSP and AIX applications. [5]
The IBM AS/400 (Application System/400) is a family of midrange computers from IBM announced in June 1988 and released in August 1988. It was the successor to the System/36 and System/38 platforms, and ran the OS/400 operating system.

Release 9 was issued in 1981. In 1983, IBM repackaged SSP on a new computer called the IBM System/36, which was not object-code compatible with the S/34. In 1994, IBM repackaged SSP on an updated model of the S/36 called the Advanced/36. The A/36 was an IBM AS/400 which had the SSP implemented as a "virtual machine". Major releases of SSP ...
