AS/400

(Application System/400) The first generation and original name of IBM's System i midrange business computers, which merged into the Power Systems brand. Introduced in 1988, the AS/400 successors are IBM's only non-mainframe, business computer family that uses IBM hardware. The other non-mainframe business series is IBM's System x, which uses x86-based servers. See Power Systems and System x.

Designed to Consolidate
The unique feature of the AS/400 was its OS/400 software environment, which included an integrated relational database. Also a feature of the earlier System/38, System/38 applications ran intact on the AS/400, but System/36 programs had to be recompiled.

The AS/400 served in a variety of networking configurations: as a host or intermediate node to other AS/400s, as a remote system to mainframe-controlled networks and as a network server to PCs.

POWER Based
In 1994, IBM introduced the AS/400 Advanced System/36, a PowerPC-based version of the AS/400 that natively ran the System/36 SSP operating system and its applications. Starting that year, IBM's POWER CPUs were used in AS/400 models. See POWER, System/36 and System/38.

An Early AS/400

The AS/400 has been used in businesses of all sizes, and thousands of applications have been written for it. (Image courtesy of International Business Machines Corporation. Unauthorized use not permitted.)

(computer)

AS/400 - An IBM minicomputer for small business and departmental users, released in 1988 and still in production in October 1998.

Features include a menu-driven interface, multi-user support, terminals that are (in the grand IBM tradition) incompatible with anything else including the IBM 3270 series, and an extensive library-based operating system.

The machine survives because its API layer allows the operating system and application programs to take advantage of advances in hardware without recompilation and which means that a complete system that costs $9000 runs the exact same operating system and software as a $2 million system. There is a 64-bit RISC processor operating system implementation.

Programming languages include RPG, assembly language, C, COBOL, SQL, BASIC, and REXX. Several CASE tools are available: Synon, AS/SET, Lansa.
