Applications

The AS/400 platform was designed for enterprise business applications spanning inventory management, payroll processing, accounting, and general business data operations. It operates as a midrange computer capable of handling mid-scale business requirements and supports compatible IBM systems including the iSeries, System/36, and System/38 environments. This system dates from the era when IBM dominated midrange business computing (1980s–1990s); the AS/400 line became the foundation for modern IBM Power Systems and remains a recognized standard in legacy enterprise environments. The integrated tape drive provided native backup capability essential for mission-critical business data protection. While superseded by modern server architectures, the AS/400 remains valued in operational legacy systems, data archaeology, and historical IT preservation applications.
