Grace is right, Reggie - the iMac itself will support 1GB of RAM, but the people who set it up installed only 763k

This is a work computer for a national/international development organization. There are tons of amazing photos and many documents going back years.

So...I will check with Utilities to see the kind of RAM the iMac has, as they have a few old Macs in the basement...which just might have some RAM worth taking!

Thanks for all your thoughts, folks!
