Apple 2300 Series Laptop User Manual


 
IMPORTANT
You cannot use the PowerBook Duo Dock, an earlier model of
dock, with your Macintosh PowerBook Duo 2300 series computer unless it
has the Top Cover Upgrade installed. (The upgraded top cover has a door
covering the opening at the front of the dock.) The upgrade is available from
an Apple-authorized dealer.
You can also use your Macintosh PowerBook with the Duo Dock II or a
Duo Dock (with the Top Cover Upgrade). These docks are earlier models
that have somewhat different features from the Duo Dock Plus.
The Duo Dock Plus comes with many built-in features; several optional
features are also available. These features include
m an internal 1.4 MB floppy disk drive
m an optional internal SCSI hard disk drive (any available capacity that meets
Apple’s specifications; up to 1 inch high)
m standard ports including SCSI (with an HDI-30 connector), monitor,
printer, modem, Apple Desktop Bus (ADB), sound input, sound output,
and EtherTalk
m a separate mouse and keyboard
m slots for two NuBus cards for additional video, Token Ring, or other
capabilities. When using the Macintosh PowerBook Duo 2300 in any Duo
Dock model, the NuBus cards installed cannot consume more than 15
watts of power. Check the documentation that came with your cards to
determine their power consumption. (Note that if you use two NuBus cards
in your Duo Dock Plus, the bottom of your PowerBook may feel warm
when you eject it from the dock. This is normal and will not harm your
PowerBook.)
m built-in video support for a wide variety of monitors
m 1 MB VRAM for 16-bit color on 16" or smaller color monitors, 8-bit
grayscale on the Apple 15" portrait monitor and the Macintosh Two-Page
Display, and 8-bit color on 17" or larger color monitors
m an automatic insert/eject feature to ensure reliable docking
m a key-operated lock to prevent theft of the docked PowerBook
m a slot door that protects the interior of your Duo Dock Plus when your
PowerBook is not docked
