Applications
Token Ring was IBM's primary LAN technology through the late 1980s and into the mid-1990s, running at 4 Mbps and later 16 Mbps over shielded or unshielded twisted-pair cabling. The Madge Blue+ 16/4 was a widely deployed ISA Token Ring adapter, used in IBM-compatible PCs connected to corporate Token Ring networks running IBM mainframe, AS/400, and LAN Server environments. Madge Networks was one of the leading independent Token Ring NIC vendors of that era, with cards like the Blue+ series supporting both the RJ45 (UTP) and DB9 (STP/IBM Type 1) cabling infrastructures common at the time. These ISA Token Ring cards are now primarily sought by organizations maintaining legacy IBM network infrastructure, vintage computing enthusiasts, and those restoring or preserving 1990s-era enterprise systems. The ISA bus interface means this card requires a system with an ISA slot, typical of PCs from the early-to-mid 1990s — an era when ISA was beginning to give way to PCI as the dominant expansion bus standard.
This Madge Blue+ 16/4 ISA Token Ring Network Card (P/N 152-320-01) has been inspected and is in good used condition. It was pulled from a working environment where it was previously in use. The card shows normal surface wear consistent with prior installation. The RJ45 and DB9 bracket ports are present and intact. The PCB is clean with no visible damage, broken traces, or missing components. 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.
