I have an old iMac g3 w/ a 266 MHz PowerPC processor, 160MB of RAM, and a 6GB Harddrive. It is running OS X 10.2.8. I need to get rid of it, but I want to make sure it is cleared of all my data first. Maintaining functionality would be nice so that I can try to sell it. My problem is that I don't have the original install disks. So...how can I can wipe the memory from my iMac and restore it to a usable condition w/o the install disks. Your help is appreciated.
