Applications
Token Ring was IBM's primary local area network technology from the mid-1980s through the 1990s, used extensively in corporate environments running IBM mainframes, AS/400 systems, PS/2 workstations, and PC/AT-compatible machines. Unlike Ethernet's CSMA/CD approach, Token Ring used a deterministic token-passing protocol on a logical ring topology, which gave it predictable performance under load — a key reason it was favored in banking, manufacturing, and enterprise data centers of that era. The Madge Smart series was among the most widely deployed Token Ring adapter families, known for strong driver support across DOS, OS/2, Windows, and NetWare environments. Today these cards are sought by administrators maintaining legacy IBM network infrastructure and by collectors preserving vintage corporate computing environments from the late 1980s and 1990s. The dual RJ-45/DB-9 bracket makes this card flexible for either shielded or unshielded Token Ring cabling plants.
This Madge Smart 16/4 AT Ringnode Token Ring Network Card (P/N 152-048-06) has been inspected and is in good used condition. It was pulled from a working environment where it was in active use. The PCB shows typical light handling wear; the bracket, RJ-45 port, and DB-9 connector all appear intact and undamaged. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
