    • For Older IBM AS400 Models

    IBM AS/400 Compatible Adapter Cards (Older Models)

    Enhance connectivity, networking, storage, and I/O capabilities on your older IBM AS/400 servers with compatible PCI and PCI-X adapter cards at Data Tech Computer. We offer a selection of legacy enterprise-grade adapters (Ethernet, Fibre Channel, SCSI, RAID, and more) optimized for classic AS/400 models including 9406-170, 9406-270, 9406-500, 9406-600, 9406-620, 9406-720, 9406-730, 9406-740, 9406-800, 9406-810, 9406-820, and similar early PowerPC-based systems. These adapters provide reliable performance and compatibility to support legacy OS/400 workloads (V4R5–V5R4), basic ERP, financials, distribution, databases, and business applications still running in production on these classic AS/400 platforms.

    Key Benefits for Older AS/400 Adapter Cards

    • PCI and PCI-X support – up to 1 Gb Ethernet, 2 Gb Fibre Channel, Ultra320 SCSI
    • Solid networking and storage connectivity for early LAN, SAN, internal/external disk, and tape
    • Full IBM feature code compatibility (e.g., 5700/5701, 6227/5758, 5736/5738 equivalents)
    • ECC and enterprise reliability for mission-critical legacy environments
    • 60-day warranty on all older AS/400 adapter cards
    • Ideal for maintaining or refreshing classic AS/400 systems with additional ports, networking upgrades, SAN connectivity, or storage expansion before migration
