Applications

Token Ring network adapters were standard connectivity components in IBM PC/AT and compatible systems through the 1990s, primarily in corporate and institutional networks. The TC9145 connects ISA-bus computers to Token Ring LANs, supporting both 4 Mbps and 16 Mbps ring speeds via onboard configuration. Historically used in office workstations, servers, and industrial control systems requiring Token Ring connectivity.

Condition: Used
This Thomas-Conrad TC9145 16-Bit ISA Token Ring Network Card has been inspected and is in good used condition. The PCB is clean with no visible damage, broken traces, or missing components. The bracket is intact with both the DB9 and RJ-45 ports present and undamaged. The two LED indicators on the bracket are intact. The onboard DIP switches and media jumper are all present. Normal light handling wear is visible consistent with prior installation and removal from a system. 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.
