Would a 1.33GHZ or 1.5GHZ Logic Board Work?

I'm curious to know if either or possibly both a 1.33GHZ 2nd gen 2004 or a 1.5GHZ 3rd gen 2005 logic board would work in a 1.25GZH 1st gen 2003 aluminum G4 Powerbook??

Okeydok....Thanks lemerise....I'm now considering swapping the 1.25GHZ LB in my 15.2" screen G4 Powerbook with the faster processor of a 1.33 or 1.5GHZ board. I just wanted to make sure of the compatability....Cheers


You're not going to get a significant performance increase though. Unless for some reason you're in love with your 6-year-old computer, you might want to consider investing the money in a MacBook.


This is more of a hobby project for me really which is also designed to further develop my somewhat limited computer repair skills. The powerbook was originally given to me with a damaged lcd screen which I successfully replaced but I've since discovered that the logic board was also damaged, so I purchased another board off Ebay only to find it suffered from lower ram slot failure, which I've in fact received a partial refund for. Therefore I'm going to purchase another LB from another Ebay source (unfortunately they didn't have anymore 1.25GHZ boards in stock) so I thought I might just as well see if I could indeed put one of the above mentioned LB's in it, which I can get from this seller for a reasonable price. Altogether the cost of this entire project is going to amount to somewhere between $200-$250. In the end my main goal is to try and make this Powerbook work as well as it did when it was brand spankin' new....Or maybe even a "little" better....;-)....Just for the fun and knowledge of it....:-)


Sounds good, and have fun! I only mentioned the above because a lot of people think they are going to get a 50% performance increase from this kind of upgrade, in which case I try to let them know that it's probably not going to be the case. :-)


Thanks rdklinc....I appreciate your input.
