Description
Kingston KNE30BT EtheRx PCI Network Card 10Base-T 10Base-2 BNC RJ-45 10 Mbps
The Kingston KNE30BT EtheRx is a PCI Ethernet network adapter that supports both 10Base-T (RJ-45) and 10Base-2 (BNC/coax) connections simultaneously, making it a versatile card for legacy 10 Mbps Ethernet environments. It is built around the Realtek RTL8029AS controller, a widely used NE2000-compatible chip. The card fits a standard full-height PCI slot and presents both connectors on its rear bracket.

Applications
The KNE30BT was designed for desktop PCs of the mid-to-late 1990s, the era when 10 Mbps Ethernet was the standard for small office and home networks. The dual-connector design — RJ-45 for twisted-pair structured cabling and BNC for thinnet coaxial bus segments — made it especially useful in mixed environments where both wiring types were present. The Realtek RTL8029AS chipset was near-universally supported by operating systems of the period, including Windows 95/98/NT, DOS, and early Linux, and drivers remain available for legacy system restoration today. Cards like the KNE30BT are still sought after for vintage PC builds, retro LAN parties, and maintaining older industrial or embedded systems that use 10Base-2 coax segments — a topology that had largely disappeared from modern networks by the early 2000s.
This Kingston KNE30BT EtheRx PCI Network Adapter Card has been inspected and appears to be in good used condition. The PCB is clean with no visible damage, and both the BNC and RJ-45 connectors on the bracket look intact. There is light handling wear consistent with prior use. The card has not been powered up or tested at our facility, but it came out of a working environment where it was previously in service. Please review our photos and contact us with any questions.
