The ultimate Apple II machine. Was a true godsend in its time, the IIgs had an Ensoniq synthesizer chip that gave it amazing sound abilities for a 1986 computer, and an RGB monitor for displaying clear colors. (Previous Apple II machines used composite video which sucked). The Apple IIgs was also the first Apple ever to use the Apple Desktop Bus. At its heart was a WDC 65c816 processor, which can address up to 16MB of RAM natively (though the GS could only be upgraded to 8 max)
