networking and communications, and additional processing power. Your
Macintosh has three slots available for the following kinds of expansion
cards:
m an LC-PDS (processor-direct) slot for most cards
m a communications slot for an internal modem or Ethernet card
m a video-in slot for a card that brings signals into the computer from a
videocassette recorder (VCR), laserdisc player, video camera, or similar
device
You can also install a TV tuner card that allows you to watch TV on your
