Hi callis1, welcome to the Linux Mint forums
Thanks for joining the forums! As for your question about ideas for distros to run on your PowerPC, DistroWatch to the rescue! Here is their list, with summary, of the distros supporting PowerPC: http://distrowatch.com/search.php?architecture=powerpc
. I'd probably go with Debian (http://www.debian.org/ports/powerpc/
), but Yellow Dog Linux (http://www.yellowdoglinux.com/
) also looks nice.
Be sure also to check out the Community
website (tutorials, hardware and software reviews, ideas). You can also chat in real-time with other Linux Mint users. In the Mint Menu, in the Internet section, start the application Quassel IRC. After a short set up, you will get connected to #linuxmint-chat for general chat and #linuxmint-help for support with other Linux Mint users.
Have fun with Linux Mint.
