Hello, I have 9.1 and 9.2.1 but they will not install on this particular machine. After doing some research at the Apple site I found that some computers come with an OS disc that is particular to that model. This appears to be one of them. I also own every OS X released to date. I have not tried any of the earlier incarnation, only Panther. To load any of the earlier systems would require an "erase and install" I believe. I installed Panther twice and both times "it" requested the OS 9 disc. For the most part I did the recommended installation, I did leave out the Asian Fonts and a few other minor things that I always do. When I try to load applications that require OS 9 to run I am told that it (OS 9) cannot be found. There are a few "Classic" files on the HD but they appear to be the "links" between the two OS's. There is not a folder on the HD titled "Applications (Mac OS 9)" which is all the others I have installed 10.3. It sounds like I need the OS 9 disc that came with the early Ti-Books or I'll have mail it off to the closest dealer.
