I recently got an iMac G3 from a friend because he claims it doesn't work. When you turn it on you are greeted with a blinking finder and then question mark. He gave me the iMac OS 8.6 which brings the mac out of the cannot find finder and brings the mac to its desktop, but almost nothing works. I was wondering how I do a clean instal deleting everything that was once on it and just leaving what it came with originally. I do not have a usb keyboard so I am not able to press any keys. Thanks in advanced.
