I got one of these Macs from ebay for my young kids to use for internet access (nick jr, disney, that kind of stuff). It only came with 256mb or ram so it desparately needs an upgrade. PC100/133 ram is getting so expensive its almost not worth buying it anymore. But I just came across this, seemed like a great deal if it works. http://cgi.ebay.com/NEW-512MB-PC133...ryZ14913QQssPageNameZWDVWQQrdZ1QQcmdZViewItem edit - guess I could have read the description a little better. Says "will not work in Apple machines." Why is that?
