So the Quadra's were more popular...that is good, because my Centris 610 has a damaged internal Superdrive, and possibly even the hard drive. I don't want to have to keep reinstalling the OS to make it work. Actually, my first goal, before I start replacing the damaged parts, is to save all the files on its hard drive. Obviously, to do that, I'll need a working Superdrive. I'm going to try and see if an external Zip drive will work, but somehow I doubt it. Anyway, thanks everyone. Based on what you all have said, there is new hope that my '610 can be fixed after all. I'll let you know how everything goes.
