I was at a thrift store and saw a original iMac for $50. They let me test to see if it still worked and it it came on and booted into Mac OS 9.2.2 so being a Apple fanboy I purchased it on the spot. However, I'm having some problems. The computer seems to be locked down pretty secure, I noticed that it was once used in a school and that is perhaps why. I was wanting to update it to OS X 10.0 but any attempts are futile. Is there any utility disc I could burn that would let me just wipe the entire hard drive? Or something like that? Any help is appreciated, thanks!
