I was installing these chips in a G4 Sawtooth macintosh computer and the chips did not work. I had kernel panics that eventually left the operating system unusable. The hard drive had to be reformatted and the OS re-installed. A great headache and PITA. I need to return these memory modules, how would I do that.best regards,vilppu

I've heard it said that this is Kerouac's greatest novel. I still say that honor is held by On the Road, but this book is just as good. And it is his most spiritual novel. Kerouac combines his talent at writing with his philosophy of life and what you have is a powerful tool to enlightenment. This book should be read on at least two levels, as a work of great literature and as a theological tool. I can't recommend it enough.

The adaptor that comes with the Apple Powerbook did not last as long as it should have! Then to charge that expensive cost for replacement...Shame on them! I accidentally dropped and bent the first adaptor that I bought from you and replaced it and still have enough left over to buy another if needed!!! WHY? Apple?
