Just curious. I would like to upgrade the OS on my niece's old G3 (233 MHz) from the OS 8.6 she's still running. I have it installed on my old 400 MHz G3 Powerbook and I don't think those systems are that different. I'm not too worried about performance since they are not doing enything too demanding. At some point I will help them upgrade to a newer system but that's not an option right now. Thanks in advance for your input.
