|This is the fifth and most powerful model in the Apple II series featuring true 16-bit architecture, increased processing speed, direct access to megabytes of RAM, wavetable music synthesizer, graphical user interface, and mouse! Wow these are great specs back to '86 while Atari had the St series already in teh shelves and Commodore had the newly (though too expensive) incredible Amiga 1000 ready to go on the market!
The Apple IIGS was the first computer produced by Apple to use a color graphical user interface (the ST computers run TOS on monochrome modes) and also was also the first personal computer to come with a built-in "wavetable" sample-based synthesizer chip, utilizing technology from Ensoniq. Well unfortunatelly as said above, the Amiga 1000 was about to launch.
The IIGS sports a 65C816 16-bit microprocessor running at 2.8 MHz, which was capable enough for its time though a decision that had a critical effect on the Apple IIgs' success with its main competitors, the Atari ST and Amiga.
Note that the IIGS series included enhanced graphics and sound (comared to the Mac series), which led to its GS name. Its graphics were the best of the Apple II series, with new Super High Resolution video modes. These included a 640x200-pixel mode with 2-bit color and a 320x200-pixel mode with 4-bit color, both of which could select 4 or 16 colors (respectively) from a palette of 4,096 colors. It is also capable to display up to 256 colors on-screen!
The most impressive though feature of this systems, is its sound capabilities. The Ensoniq ES5503 DOC wavetable sound chip allowed for 32 separate channels of sound, though most software paired them into 16 stereo voices!
Like the Apple IIe before it, the IIGS was highly expandable. The expansion slots could be used for a variety of purposes, greatly increasing the computer's capabilities. SCSI host adaptors could be used to connect external SCSI devices such as hard drives and CD-ROM drives. Other mass storage devices such as adaptors supporting more recent internal 2.5-inch IDE hard drives could also be used. Another common class of Apple IIGS expansion cards was accelerator cards
