OS: ProDOS 16, System 1.x to System 6.x
Development status: Open
Platform size: 1
This post-Mac machine expanded significantly upon its 8-bit processor by using a 16-bit processor that allowed utilization of more system memory and faster program execution. A new graphics chip and an impressive sound synthesizer further differentiated the IIgs from its 8-bit cousins.
As a member of the Apple II family, the IIgs’s WDC 65816 processor contained an emulation mode that could execute programs written for the original Apple II’s 6502 processor at roughly twice the speed, thus carrying on the vast legacy of Apple II software products.
