 TOPIC -----------------------------------------------------------

 This article describes the Apple IIGS personal computer model with 1MB of
 RAM and ROM version 03.

 DISCUSSION ------------------------------------------------------

 OVERVIEW
 --------
 The Apple IIGS combines the best of the previous Apple II computers:
 built-in accessory ports for easy addition of peripherals, as well as
 versatile expansion slots for system customization.  The Apple IIGS also
 provides an easy-to-use interface similar to that of the Macintosh personal
 computer. It also offers powerful features such as high-resolution color
 graphics, 15-voice sound capability, and the advanced 65C816
 microprocessor.

 The Apple IIGS features GS/OS, an operating system developed exclusively
 to take advantage of the computer's hardware features.  GS/OS offers
 high-performance capabilities such as rapid disk access and program
 launching, while increasing the system's ease of use.

 SYSTEM SOFTWARE
 ---------------
 The Apple IIGS Personal computer features Version 5.0.4 of Apple IIGS
 System Software, including the following:

 * GS/OS Operating System.  Exclusively created for the Apple IIGS
  personal computer, GS/OS dramatically increases the speed of both disk
  access and program launching.  It also includes File System Translators
  (FSTs)  that allow applications to directly access files created using
  other file systems, such as the ISO/High Sierra file system used by
  CD-ROM devices.

 * Finder.  The Apple IIGS Finder has been revised extensively to take
  full advantage of the GS/OS operation system.  In addition to providing
  support for disk partitions and other new features, the Apple IIGS
  Finder is easier to use, faster, and more informative than the
  earlier version.   The Finder also supports the AppleShare File Server,
  allowing you to share program files and data with other AppleShare
  users.

 * Advanced Disk Utility.  With its graphics-based interface, the
  Advanced Disk Utility makes it easy to initialize, name, erase,
  and partition hard disks, as well as to work with both 5.25- and
  3.5-inch floppy disks.

 * Installer.  This program allows you to update your startup disks with
  the latest system software.  It also lets you add special system files
  to customize startup disks for use with your particular system
  configuration.
