Saving the zombie in south carolina

So, yeah. with the acquisition of the 4x4, my old computer ('512 megs of fail') has been redesignated 'zombie'. i'm not sure what to do with it. i don't want to throw it away and doom it to a landfill (the only thing wrong with it is that the OS is screwed up), but it's been replaced. i could sell it (i'd get 200$ max), or i could trade it off...
Maybe i could install Linux or FreeDOS.

Also, tomorrow i'm headed out to South Carolina to see my sister graduate from her Basic Traning in the national guard at Ft. Jackson. After a field trip at school. Awesome.
