New, boxed Farallon EtherMac 10Mb Combo PCI EtherNet Card (10base2 and 10baseT) for Macintosh computers with a PCI slot. Includes sealed PCI card, new UTP ethernet cable, BNC T-piece, driver software on floppy disk, and documentation. The box is open and tatty.
This card requires Open Transport to be recognised which is installed as standard on Mac OS 7.6 and later. If you are running System 7.5.3 or 7.5.5 and are using Classic Networking, you will need to switch to Open Transport.
Note that thin ethernet networks require termination with a 50ohm BNC terminator at each end of the chain (unless the last node is an Apple AAUI transceiver which self terminates).
