Your Macintosh PowerBook has two PC Card slots: an upper slot and a lower slot. You can insert a card into either slot, or you can use both slots simultaneously.
There are three types of PC Cards. The different types refer to the thickness of the card. A Type I card is 3.3 millimeters (mm) thick, a Type II card is
5 mm thick, and a Type III card is 10.5 mm thick. Make sure you check the documentation that came with your PC Card to verify that it is compatible with your Macintosh PowerBook.
WARNING Make sure you only use cards that are designated by the PC Card manufacturer as compatible with your Macintosh PowerBook. If you use an incompatible card, you may damage the card or your PowerBook. If you are not sure whether a PC Card is compatible with your PowerBook, contact the PC Card manufacturer.
You can place a Type I or Type II card in either the upper or lower slot. You can place a Type III card only in the lower slot. When a Type III card is in the lower slot, you cannot use the upper slot. You may find it useful to get in the habit of always using the lower slot to make sure the card you are using is properly inserted.
A special type of PC Card supports “zoom video,” a method of showing full- motion video images in a window on the computer’s screen. Your PowerBook is designed to use a zoom video card, but this type of card must be placed in the lower PC Card slot.
