I have two 256 MB SDRAM SO-DIMM 144-pin chips that are free to whomever wants them. They came with my 800 MHz TiBook, but taken out when I upped it to 1 GB. I just tested them on my roomie's old G3 iBook, and they work just fine. I have a 12" PowerBook and can't foresee having to downgrade at any point. So, yeah, if you want 'em, get in touch with me. I'll even throw in shipping via U.S. Priority Mail. Cheers.
