From what I see, my iMac cannot currently read. The only problem is I can't find Cheetah anywhere, and if I find it online to download, it's either a. The person at Apple said it needs to be upgraded to 10.0 (Cheetah) before I can keep upgrading apparently. I've been trying to upgrade it, and just can't get it to work at all. The iMac is curently running Mac OS 9.2.2 and runs perfectly. I recently picked up an iMac G3 (light blue color) at a little store for just $10.00 - I gave Apple a call and apparently the iMac has enough RAM and all that fancy stuff for a couple of upgrades based on their calculations.
