Once a year I get to ask you Macintosh people a question. Sorry I'm so late! My in-laws are using a very, very old old iMac and I think it's running system 7. I'm not looking at it right now, sorry about that, too. I'm going over tomorrow to hook up their DSL modem. What do I need to do to install the requisite software, which requires at least v9 but preferably OSX? If I buy them a mini, can I use the iMac as a monitor?
