Applications
The IBM 72H3496 was a standard solution for connecting IBM personal computers and workstations to Token Ring local area networks (LANs), which were prevalent in IBM-centric enterprise environments throughout the 1980s and 1990s. Token Ring networks offered deterministic performance and were favored in mission-critical corporate settings before Ethernet became dominant. This card was used in offices, data centers, and industrial control environments where reliable, predictable network access was essential. Token Ring technology is largely superseded today, but this hardware remains valuable for legacy system maintenance, museum collections, and retro computing enthusiasts seeking to restore original IBM systems to working network-connected condition.
