Funny that this subject should recur. It was just in last December that
it last came to a halt, when Don North (North@Apple.com) wrote in
article 5875 in this group that you are *always* mixing speeds when
adding any RAM to any Mac and that as long as the minimum speed requirement
for that particular machine type is satisfied, the speed simply does not 
matter. TN 176 of Apple has got it wrong, he said as well. If you have
lost track of that article, please ask me to mail it to you.
