Apple GS/OS


The Apple GS/OS is a disk operating system developed by Apple in 1988 especially for the Apple IIGS computer. The GS/OS has been publicly released on 16 September 1988 and was developed until version 4.02 released on 6 May 1993.

Apple GS/OS is a second operating system after Apple ProDOS 16, but first written entirely to support the 16-bit architecture used in Apple IIGS. The big change from the previous versions of ProDOS is that GS/OS contains many features of the Macintosh System. In practice, GS/OS has a Finder, loadable fonts, and plug-in device drivers like modems or printers.

Today Apple GS/OS is 33 years old!
