System Overview 1-19
PC Adapter Device
Some desktop and minitower systems come with a PC Adapter Device. The PC
adapter provides twin PC card slots, which support two Type I/II cards, or one
Type I/II card and one Type III card. The adapter supports ISA Plug and Play,
and allows cards of mixed voltage to be used in the same system. PC cards can
provide the system with memory, storage, fax/modem capabilities, video
capabilities, or a serial port interface. The PC adapter driver enables full diskette
drive or hard disk emulation on flash cards compatible with all compression and
PC-utilities software.
The adapter is comprised of a “SwapBox” housed in a 5 1/4-inch accessible bay,
a PC ISA adapter card, and a dual cable that connects them on the PC
adapter bus.
PC adapter device specifications are given in Section 10, “Specifications.”
Tape Backup Unit
Some desktop and minitower systems come with a tape backup unit. The tape
backup unit is a high-capacity, high-performance data storage device that can
compress and write data to and read and uncompress data from tape. The unit
also comes with backup software used to tailor the backup process so that some
or all of the files on the system can be backed up to a tape cartridge. Files
backed up to a tape backup unit are compressed to conserve space and to speed
up the backup process.
The tape backup unit installs in a 5 1/4-inch accessible bay. The installed tape
backup unit is connected to an IDE cable that connects to the riser board. The
PCI/IDE channel and the master/slave configuration of the unit depend on the
specific configuration of the system.
PCI/IDE connector locations on the riser board are given in
Section 5, “Riser Board.” Tape backup unit specifications are given in
Section 10, “Specifications.”
Zip Drive
Some desktop and minitower systems come with a Zip drive. The Zip drive is a
high-capacity, high-performance data storage device that writes data on and
reads data from Zip disks. A Zip disk is flexible media contained in a durable
plastic cartridge. The Zip drive supports removable Zip disks with a formatted
capacity of 100 MB. The Zip drive can be used to back up work, archive old
files, and transport work between computers.
The Zip drive is installed in a 5 1/4-inch accessible bay. The installed Zip drive
is connected to an IDE cable that connects to the riser board. The PCI/IDE
channel, and the master/slave configuration of the drive depend on the specific
configuration of the system.
PCI/IDE connector locations are given in Section 5, “Riser Board.” Zip drive
specifications are given in Section 10, “Specifications.”
