Clemens a number of folks, specifically Jake Luck, have done it on the 2400, but it's really....really slow. The RAM requirement seemed to be the biggest constraint, even with 112MB. There's a bit of info in the archives, though we never did a write-up on the 2400 site summarizing the issues, unfortunately.

I have recently purchased a 96meg RAM chip which will arrive in about a week. My question is...How much faster is OSX with 112meg than with 80meg? Has anyone experienced both? uh...a whole lot slower than a TiBook or new iBook, with 128/256/512/1GB available at much lower cost. Yeah, I know, I am being *way* too practical! =) *********************** Jake's OS X posting: http://www.mail-archive.com/duolist@lists.themacintoshguy.com/ msg13551.html On Mar 27, 2004, at 3:48 AM, Clemens P.B.
