for a mac
 

I've got an old macintosh performa 6200 (like 7 years old or something)
it is power pc, but as i am not a mac user (i can't even figure out how to open the damn thing) i don't know much else about it, but i think it's got a 2 gig hard drive.

other than yellow dog, what distros can i run on this thing, and which yellow dog would be best, i can't find anything older than 2.0

thanks

Mandrake PPC?

LWN's ppc distro page may have what you need.
