Encore ESL-835-TB 32-bit PCI Ethernet Network Card BNC RJ-45 RTL8029AS

Encore ESL-835-TB 32-bit PCI Ethernet Network Card BNC RJ-45 RTL8029AS

The Encore ESL-835-TB is a 32-bit PCI local bus Ethernet adapter supporting both 10Base-T (RJ-45) and 10Base-2 (BNC coax) network connections on a single card. It is built around the Realtek RTL8029AS controller — one of the most widely used 10 Mbps NE2000-compatible chipsets of its era — and fits any standard 32-bit PCI slot.

Applications

The ESL-835-TB was designed for desktop PCs from the late 1990s and early 2000s with 32-bit PCI slots, at a time when both twisted-pair (10Base-T) and coaxial (10Base-2 / thinnet) Ethernet cabling were still in active use in offices and labs. The dual-port design let a single card serve either network type without requiring a separate adapter. The Realtek RTL8029AS chipset was NE2000-compatible, making it broadly supported under MS-DOS, Windows 95/98/ME/NT/2000, Linux, and other operating systems of that generation. Today these cards are primarily sought by vintage PC enthusiasts, retro LAN party builders, and administrators maintaining legacy systems that require thinnet coax connectivity — particularly in industrial, educational, or government environments where older BNC-wired networks remain in service.
