Another very viable Linux distro for little machines
is Puppy Linux. An
80M-90M download, it is full-featured and fast. If
you decide to download
it, also download BurnCDCC from the link on the Puppy
site. You will need
it to burn a CD of the iso. The iso comes as a zip
file, so if you need a
zip utility to open it, get 7-ZIP which is quite good
and free. Good luck.
