About expansion cards
Expansion cards are printed circuit boards that can be installed in your
computer to give it special features, such as enhanced video capabilities,
networking and communications, and additional processing power. Slots that
will fit three different kinds of expansion cards are available within your
Macintosh:
m a PCI (peripheral component interconnect) slot for most 6.88-inch cards
m a communication slot for an internal modem, fax, or Ethernet card
m a video-in slot for a video input card that brings signals into the computer
from a videocassette recorder (VCR), laser disc player, video camera, or
similar device
