Apple 280C Laptop User Manual


 
The drawing below shows one of many possible PowerBook Duo systems.
The Duo Dock and Duo Dock II come 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, and sound
output. On the Duo Dock II or upgraded Duo Dock, an EtherTalk port is
also provided.
m a separate mouse and keyboard
m slots for two NuBus cards for Ethernet, Token Ring, additional video, or
other capabilities. (Note that if you use two NuBus cards in your Duo Dock
or Duo Dock II and you dock a PowerBook Duo 280 or 280c, the bottom
of your PowerBook Duo may feel warm when you eject it from the dock.
This is normal and will not harm your PowerBook Duo.)
m a math coprocessor (FPU) on the Duo Dock II or upgraded Duo Dock (a
socket for an optional math coprocessor is provided on the Duo Dock) if
you are using the dock with a PowerBook Duo 230
