As the new school year starts you may be thinking about what you can do to give your old computer new life, or how to enhance a computer you are handing down to your kids. A recent Tech Tip column in The New York Times covers just that topic and discusses how adding RAM (Random Access Memory) or a new hard drive can revamp an old machine. A simple but useful one-stop shop for Macintosh users looking to upgrade can be found on Other World Computing’s My Upgrades page. There, you can enter the computer’s model number and it will generate a list that shows you all the components of the computer that can be upgraded. You can even buy the parts right there.
