I should try again to research this myself ... But since a few of you seem to know something about linux on macs and I haven't found much in the past regarding my particular hardware when I have looked ... I have an old PowerMac 7500 upgraded to a maxpowr G3 300MHz cpu (originally with a 601 100MHz chip). This is a PCI powermac. Do you know if I can get linux to run on this machine? The thing's been powered off for almost 2 years ... but, one of my longstanding todo items is getting it going as a linux box to have as a backup for web/mail/irc/etc and possibly basic recording duty in case I totally hose my main audiobox someday. Any pointers or experiences with this or similar hardware? Thanks, Eric Rz.
