Don, YES! If you go to "download.com" (without the quotations) and search the system software section (Drivers & OS Updates - click on System Updates) for the upgrade files, you can download version 9.1 and use it to upgrade your current OS version so that it will be compatible with the software you want to install. If I remember correctly from your earlier post, you do have at least version 9.0 installed. From that version, you can do the upgrades to later versions of OS 9, all the way to 9.2.2 if you want. I recommend doing the upgrade up to 9.2.2 as I think it is more stable than the earlier OS 9 versions. When I first installed OS-X in my G4, it was a simple install from the system CDs to put both OS-9 and OS-X on the hard drive. I never had to wipe anything when I did the upgrades to later versions, so I don't know why your friend is telling you to wipe OS-X first. It sounds like he is a PC user. From my experiences, simply download the upgrade and run it from the expanded file that you will find where you normally put your downloaded files. It will install right over the original OS version and give you some added functionalities and improvements. You could also consider upgrading your OS-X to version 10.3.2 but I suggest at least a DSL connection for that or you will be downloading for a while. Good luck, Ron
