Hello Eric and all! I have the same problem. I like my G3 very much but I have a rather large paperweight in my office...a Mac Quadra 660AV. Looked on the Sonnet sight and did find several products but am unclear as to what they will really do to the machine. Has anyone out there actually upgraded their old Mac? I guess I could look into donating it to a school, but at 33 MHz, it won't run a lot of fancy programs. It won't even run my 3 year old's Blue's Clues game. Ideas? Taina
