Some models of the Macintosh PowerBook come with a card installed in the
PCI expansion slot. The preinstalled cards provide either modem and
Ethernet connections or only an Ethernet connection. Other models of the
PowerBook 3400 do not have an expansion card installed.
You can easily determine whether your computer has an expansion slot card
installed. Open the cover on the computer’s back panel. If a card is installed,
you’ll see a modular telephone-style connector (a socket) and a label that
shows the Ethernet icon or a combined Ethernet and modem icon.
