Applications
The Xircom RBEM56G-100 was designed for laptop and notebook computers equipped with a 32-bit CardBus slot, giving mobile users both wired Ethernet network access and a dial-up modem connection without carrying two separate cards. This type of combo CardBus adapter was widely used in the late 1990s and early 2000s — the era when corporate laptops commonly lacked built-in Ethernet and dial-up was still a necessary backup to broadband. The card was popular in business environments where users needed to connect to a LAN at the office and dial into remote access servers or hotel/home phone lines while traveling. Today, the RBEM56G-100 remains useful for maintaining or servicing legacy laptops from the Windows 98, 2000, and XP era that still have a CardBus slot but no integrated network interface, as well as for hobbyists and vintage computing enthusiasts working with machines of that generation.
This Xircom RBEM56G-100 RealPort CardBus Ethernet 10/100 + 56K Modem combo card has been inspected and is in good used condition. It was pulled from a working environment where it was in active use. The card body and red dongle/port replicator show light surface wear consistent with normal laptop use — no cracks, breaks, or damaged connectors observed. The CardBus edge connector contacts appear clean and intact. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
