For sale is a set of System (GS/OS) 6.0.1 disks for the Apple IIgs. System 6.0.1 was the last GS/OS release for the Apple IIgs. All six disks necessary to install the OS on a hard drive are included. This software is freely available from Apple's website - the listing price is for the disks, labels, and my time to create the disks for you.
-System 6.0.1 requires 1MB but may need as much as 2MB, and more is recommended if you plan on running applications.
-System 6.0.1 is best run from a hard drive.
If you're looking for a single GS/OS boot disk you might want to try System 5.0.2 or 5.0.4 (5.0.4 requires 1MB of memory, 5.0.2 will run on as little as 512k), which you can find by looking at my other listings.
I use only NEW DS/DD (800k) disks that are tested good and will come with a nice compute printed label.
