You can use Debian/m68k 2.1 [slink], and help develop future versions (like potato; Debian releases have names based on the names of characters in Pixar's film "Toy Story"). Debian is available via FTP at ftp://ftp.debian.org/debian/; installation guides are available for Amigas, Ataris and Macs. Debian is also available on CD-ROMs from several vendors including Linux Systems Labs, Steve McIntyre and Chris Lawrence.

You can also use and help improve Jes Sørensen's unofficial Red Hat port, available at ftp://sunsite.auc.dk/projects/680x0/redhat/. Ron Flory has written an installation guide for this port; you can get it at http://www.feist.com/~rjflory/linux/rh/index.html. Red Hat Software is distributing this unofficial port (along with unofficial Red Hat ports for PowerPC, UltraSPARC and MIPS) as part of its Linux Rough Cuts package; you can also obtain it from Holger Lubitz, Chris Lawrence and Schatztruhe.

Eagle Linux was a distribution available for the Amiga, based on the Debian 2.0 project. You can read more about it at Eagle's web site. It has been discontinued, but you may still be able to obtain it from dealers.

Whiteline's Linux/68k is a distribution available for Ataris, also based on the Debian 2.0 project. Learn more about it (in German) at Whiteline's site.
