I just received and installed a 512 Meg Ram chip from Crucial, after the good recs on these lists, in my new 17" PB. This was the easiest to install Powerbook Ram I have ever installed... It just fit perfectly. The last three sims I bought from Ramseeker, ?, did not fit well and I had to force them. One I had to return and the replaced it. The half moon holes were miss-placed by 1/4 diameter or so. So, for now, I also recommend Crucial. --- Trees are being sucked dry of life in South Florida by a tiny insect. <http://www.lobatelacscale.com>
