Description
Tiara 41-00278-0000 Rev A PWA Lancard/E 15-00254-1 8-Bit ISA Ethernet NIC Card
The Tiara Lancard/E is an 8-bit ISA Ethernet network interface card designed to connect IBM-compatible PCs to a local area network. Identified by part number 41-00278-0000 Rev A (PCB assembly number 15-00254-1), this card provides two physical connection options: a BNC coaxial connector for 10BASE2 (thin coax / cheapernet) networks and a DB15 AUI port for connecting to an external transceiver. The card was manufactured in the USA by Tiara, as printed on the PCB silkscreen.

Applications
8-bit ISA Ethernet cards like the Tiara Lancard/E were essential networking components for IBM PC/XT and AT-class computers, as well as 286, 386, and early 486 systems equipped with ISA bus slots. During the late 1980s and early 1990s, these cards were used to connect desktop PCs to 10 Mbps Ethernet networks in offices, universities, and small businesses. The dual BNC and AUI connectors gave the card flexibility: BNC allowed direct connection to thin coaxial (10BASE2) network segments, while the AUI port supported external transceivers for other media types such as thick coax or fiber. Today, these cards are sought after by vintage computing enthusiasts, retrocomputing hobbyists, and operators of legacy systems that still require period-correct 8-bit ISA networking hardware.
This Tiara 41-00278-0000 Rev A PWA Lancard/E 8-bit ISA Ethernet NIC has been inspected and appears to be in good condition. The PCB is clean with no visible damage, broken traces, or missing components. The bracket shows normal light wear consistent with prior installation, and the BNC and DB15 AUI connectors are intact. The card was not bench-tested at our facility but was pulled from a working environment. Please view our photo set and contact us if you have any questions.
