Do you have old computer lying around in your store. Want to give life to it. Have you heard of puppy Linux?

RAM : 128 MB physical RAM for releases since version 1.0.2 or failing that a Linux swap file and/or swap partition is required for all included applications to run; 64 MB for releases previous to 1.0.2
