Connecting a mouse or other ADB device
Your computer has one Apple Desktop Bus (ADB) port, to which you can
connect low-power input devices (such as a mouse). The ADB port has this
icon: √. Connect ADB devices only when your PowerBook is off or in sleep.
Make sure that any such devices you connect are designed for portable
computers. Standard ADB devices may drain your battery very quickly, even
if the power adapter is plugged in. Low-power devices are marked with this
icon:
Á. You can attach up to three devices in a chain to the ADB port. See
the instructions that came with your ADB device or devices for information
about their power consumption, and make sure that the total power drawn by
all devices you’re connecting does not exceed 200 mA.

Sound input devices
Your computer has a built-in microphone centered just below the display. The
microphone is controlled by the program you use to record sounds. (Sound
recording is described in the chapter on sound in the
Macintosh Reference
book.)
