CyQ've ELA-110E LAN card by Sai-Cube - 16-bit PC card (Type II) compatible - 10BASE-T/100BASE-TX shared interface - 10Mbps/100Mbps auto-detection and full-duplex support - Hot-swap and auto-sleep mode features I purchased this used over 15 years ago, compatible with the NEC PC-9800 series, and have kept it in storage since. I have confirmed its operation with Debian-based Linux just before listing it. The box has considerable damage due to aging. Please purchase only if you understand the above. Immediate purchase is welcome. Thank you for looking.
