03-0020-010 - 3Com Etherlink III 16-Bit Network Adapter

Product Description

The 3Com Etherlink III 16-Bit Network Adapter (03-0020-010) is a network interface card (NIC) designed to provide Ethernet connectivity for personal computers equipped with a 16-bit ISA (Industry Standard Architecture) bus. This adapter was a popular choice during the era when ISA was the prevalent expansion slot technology in PCs, enabling users to connect their computers to local area networks (LANs) for resource sharing and communication. As part of the well-regarded Etherlink III series, this card typically offered reliable 10 Mbps Ethernet performance, adhering to the 10BASE-T standard for twisted-pair cabling, which uses the common RJ-45 connector. Some variants might have also included support for other Ethernet media types, such as coaxial cable via a BNC connector or an AUI port for external transceivers, although the 'TP' designation often implies a focus on twisted-pair. The 16-bit interface allowed for a higher data throughput compared to older 8-bit cards, making it a significant improvement for network performance at the time. 3Com's Etherlink III adapters were known for their ease of installation, often featuring plug-and-play capabilities that reduced the need for manual configuration through jumpers or DIP switches. This simplified the process for users and system administrators. While ISA bus technology is now obsolete, the 03-0020-010 remains a functional component for maintaining or upgrading legacy computer systems that require basic Ethernet networking capabilities.
