To an iBook fan, that's an iconic unit, the last, best clamshell iBook. (I would be happy to have one, just to play with it sometimes.) For speed, it needs maximum RAM, which is probably the 320MB (64 + 256) you have (though search for info, it may be that after some firmware upgrade you could have 64 + 512??). The harddrive is rather small, and since the system bus is only 66MHz it's never going to be very fast. There used to be plenty of reports of people happily running 10.3.9 on that kind of iBook, but 10.4 is probably too much of a strain for it. You can get a 10.3.9 install down to about 2GB disk space used. Good luck! On Wed, 11 Feb 2009, Josh wrote: . . . > with. I got a 466 SE with 320MB RAM and the standard 10GB HD.
