Early G3's (including your iMac) had a number of severe incompatibilites with OS X. One of the biggest was that you couldn't install OS X on one of these early G3's if it had a hard drive bigger than 8GB (something that you probably want if you are running OS X) without partitioning your hard drive so that the first partition was less than 8GB and OS X was put on that partition. Unless you do this, when you go to install OS X on one of these early G3 Macs, the choice of that drive to install on will be greyed out. http://docs.info.apple.com/article.html?artnum=106235 The technical reasons for the 8 GB requirement are interesting: http://www.macintouch.com/mosxreader10.2pt33.html There were other problems with early G3's running OS X also. Things like lack of support for built-in graphics processing, poor DVD compatibility, PCI cards not working, SCSI not working, and other drivers not working. There was a big class action lawsuit against Apple for this, and Apple settled. Since then Apple doesn't list the early G3's as being compatible with the most recent versions of OS X. http://forums.macrumors.com/archive/index.php/t-44573.html http://www.macintouch.com/mosxreader10.2pt33.html > And, yes I know it will be very slow but it will do what the > shelter knows.
