New opened box 3Com EtherLink 10/100 Mbps PCI NIC. Around when this was new, tried it in an Apple Macintosh tower. There were no drivers for the original Mac OS series, but (at least back then) there were for Windows, Linux, Solaris, maybe others. Put everything back in the box and put it in the computer closet. It’s time to clean out that closet.
Amazon has a couple of this model listed at $41. But this is Craigslist and you’re a more savvy shopper, so let’s try $10 or best offer.
