The model 3C589D-TP identifies this EtherLink III variant, a portable NIC designed to slide into a notebook’s PC Card slot and operate in the PCMCIA card format common to 1990s-era laptops. As a Twisted Pair (TP) edition, it supports 10BASE-T connectivity, typically using an RJ-45-style connector on the card for standard Ethernet patch cabling. In practice, it enabled notebook users to join local networks with compatible drivers and operating systems of the era, reflecting 3Com’s long-running EtherLink III family of PC Cards that bridged laptops to wired LANs without requiring an external desktop NIC. This description highlights the card’s core identity: a portable, late-1990s Ethernet NIC built for PCMCIA slots, offering 10 Mbps network access on copper twisted-pair networks through 3Com’s EtherLink III line.\u003c\/p\u003e\u003c\/div\u003e","brand":"3COM","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51656668152110,"sku":null,"price":33.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_502e6585-69cd-4cd6-aaff-540872e24641.jpg?v=1769462567","url":"https:\/\/plgautomation.com\/products\/3com-3c589d-tp-ethernet-local-area-network-pc-card","provider":"PLG Automation ","version":"1.0","type":"link"}
