Hi MR. Long time no see. Just bought a fantastic condition deep-blue 500 MHz G3 DV iMac yesterday for £15. Steal! The original hard drive was knackered so I've replaced it with an 80gb 5400RPM one which should be more than adequate. I'm aiming to get OS X on it. My 350 MHz G3 runs is well, so this should scream. Unfortunately, OS9.0 and OS9.1 disks in the optical drive still produce a flashing folder icon. I need to boot OS9.0 in order to flash the iMac's firmware before I can stick OS X on it, but it just won't boot at all. I'm thinking it could possibly be a knackered optical drive, but before I go to the trouble of finding a workaround, I wondered if anybody here might have some ideas. Many thanks, Alex.
