Hi Kézia Debian should run on your T3. The lastest Debian release, Jessie, doesn't have sparc support but oldstable, Wheezy, does. Follow the wheezy installation manual: https://www.debian.org/releases/wheezy/sparc/ You can netboot or install from cd/dvd. You can get an iso from here: http://cdimage.debian.org/mirror/cdimage/archive/7.8.0/sparc/ If you have any questions you can ask here on the list or in the OFTC/#debian-sparc irc channel. -David Mattli
