GS/OS is really for the Apple //GS to imitate the Macintosh. The Apple //GS was of the Apple // series but had better graphics and sound than the classic Apple // line. The Apple //GS tried to compete with the Commodore Amiga 1000 and Atari ST series, while still running classic Apple // programs. It had a 3.5" floppy drive and these GS/OS disks would install on the //GS hard drive.
