Figure 4-1 and Figure 4-2 show front and back views of the expansion bay module for a PowerBook G3 Series 1999 computer. The module is similar in shape to an expansion module for the older PowerBook G3 Series computers, but it is thinner and different in many important details.

IMPORTANT
Expansion modules for earlier PowerBook models will not work in a new PowerBook G3 series computer.
To allow room for a 5.25-inch disk, the expansion module has a wing extending toward the back of the computer. The expansion bay has a hinged door that covers the extension part of the opening when a smaller device is installed.
The expansion module has a notch on the side for the latching mechanism. The notch is on the left side of the module, which faces the front of the computer when the module is installed.
