This ISO file has been compressed with bzip2, a free and open-source compression utility. Mac OS X and Linux already have the unzip utilities built in. You can download a free unzipper for Windows at http://gnuwin32.sourceforge.net/packages/bzip2.htm

INSTRUCTIONS: First unzip the file using bunzip2. Next, BURN THE ISO TO A CD. Mounting the ISO on your machine is pointless. First of all, if you are in Windows or Linux, it won't even mount because it is an ISO of a Mac-formatted CD. If you are in OS X, it won't do any good to mount it because the installer only runs in OS 9. You have to use the image to burn a CD, and then use the CD to boot your vintage Mac, and then install the software.
