You can isnstall linux on a mac. I haven't tried it yet, though I might soon, since I now have 3 older macs that were given to me, and putting linux on one should prove interesting. There was a site (I can't remember it off the top of my head) that had versions of linux for macs already created and ready to go, but any version of linux built for the 68000 series of processors should work at least for the older macs. You might want to do a search on yahoo or something to see what you can find.
