Thank you Craig. Know about the firmware update first - which of course was done years ago. But I always double check those things before I move forward. I also know people who run OSX on computers less than 500MHz but everyting is so slow on them. Depends on what you are doing. Things take a long time to load, but run pretty well once up. Things being Safari, Office, and NeoOffice. These are donated machines at a school. Some have only 192K and 3GB disks (memory makes a bigger difference than CPU speed, of course. Craig
