This is the first mac I've been working on and I feel like I'm in the twilight zone of stupid computing. I'm trying to upgrade this Apple Performa 630CD's CPU and can't find a single upgrade PDS card. Mac users I've talked to about this seem to have no respect for older models and just say to get another computer. And all I can do is think "did I ask about another computer?". I'm beginning to lose my respect for Mac users as I am ridiculed, mocked or ignored more and more by them. All I want to know is how to upgrade my Mac Performa 630cd.
