Applications
Token Ring was IBM's LAN technology introduced in the mid-1980s, used extensively in corporate and government environments running IBM mainframe and midrange systems. The 39F8486 was designed for IBM PCs, PC/XTs, and compatible machines with 8-bit ISA slots, allowing them to participate in Token Ring networks alongside IBM AS/400, System/36, and mainframe infrastructure. Token Ring NICs of this type are sought today for maintaining legacy IBM network environments, vintage computing restorations, and compatibility testing with period-accurate hardware.
This IBM 39F8486 ISA 8-Bit Token Ring Network Interface Card is a used surplus pull. It has been visually inspected and shows normal wear consistent with previous use. The PCB appears clean with no obvious physical damage visible in the photos. The DB9 connector and ISA edge fingers look intact. This card has not been bench-tested or powered at our facility, so it is sold in as-inspected condition. 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.
