The 3Com 00500421D0D5 is a 16-bit ISA Ethernet network interface card from the Etherlink III product line, designed for legacy desktop and server systems. This twisted-pair adapter supports standard 10Base-T connectivity over RJ-45 connectors and delivers throughput typical of 10 Mbps Ethernet interfaces. The ISA form factor makes it compatible with computers featuring Industry Standard Architecture slots, common in systems from the 1980s and 1990s. This card is suited for network connectivity in older industrial control systems, point-of-sale terminals, and retro computing environments where 10 Mbps performance meets application requirements. The refurbished unit has been tested and is guaranteed fully functional and available via quote.
