Using a Zoomed Video PC Card
The lower PC Card slot in your Macintosh PowerBook has circuitry for handling
video signals, called “Zoomed Video.” Some independent manufacturers offer PC
Cards to which you can provide a video signal or connect a video camera. The
Zoomed Video PC Card is a Type II card; it can only be used in the lower slot
(because the special circuitry needed for video signals is located in that slot).
With a Zoomed Video card in the lower PC Card slot, the PowerBook can
display video on the computer’s screen or on an external monitor. Video
signals are sent directly to the video controller, so that the computer can
display full-motion video while performing other tasks at the same time.
If you purchase a Zoomed Video PC Card, be sure that it has software that
works with your PowerBook.
Using a PC Card modem
When you are using a PC Card modem, make sure you do the following:
1 Install the communications software you want to use, as well as any software that came
with your modem.
See the documentation that came with your modem and your communications
software for instructions on setting up a PC Card modem for each application.
Check to see if PC Card modem files for your software were included. You
can get other modem files from the manufacturer of your modem or your
communications software.
2 Insert the PC Card modem.
When a PC Card modem is inserted, an icon like the one pictured below
appears on the desktop:
