I have a 180 MHz part I got from a Power Computing PowerBase (CPU card) that I plan on swapping in the future. I havnt so far as the pitch between the pins is sooo damn small.... >Of course, that's neatly ignoring that I don't have anywhere near the >soldering skill required for that level of work...

Maybe. Not sure. Read off the chip part# and compare with the one on the 5300. >Peace, >Drew Mad Dog -- PowerBooks is sponsored by <http://lowendmac.com/> and...
