I have an seemingly ancient flat panel iMac that I'd like to install more memory on. It currently has two 256 mhz installed in it. I'd like to bring it up to the 1g max. Its only used for internet surfing but it can't handle youtube and I'm hoping to ratify that. Trouble is that I've never cracked her open myself and have no clue how to go about doing this. Anyone know of a good online guide??
