It emulates its predecessors via a custom chip called the Mega II and uses the then-new WDC 65C816 16-bit microprocessor. The Apple IIGS made significant improvements over the Apple IIe and Apple IIc. 7.5 Third firmware release ("ROM version 3") 1 MB of RAM.7.3 Second firmware release ("ROM version 01").7.2 Video Graphics Controller (VGC) replacement.7.1 Original firmware release ("ROM version 00").3.1 Limited Edition ("Woz"-signed case).Apple ceased IIGS production in December 1992.

It is the first personal computer with a wavetable synthesis chip, using technology from Ensoniq. It is the first computer from Apple with a color graphical user interface (color was introduced on the Macintosh II six months later) and Apple Desktop Bus interface for keyboards, mice, and other input devices. The microcomputer is a radical departure from any previous Apple II, with a 16-bit 65C816 microprocessor, direct access to megabytes of random-access memory (RAM), and mouse. The "GS" in the name stands for "Graphics and Sound," referring to its enhanced multimedia hardware, especially its state-of-the-art audio. While featuring the Macintosh look and feel, and resolution and color similar to the Amiga and Atari ST, it remains compatible with earlier Apple II models.
