well i went and bought a powerpc 3400c for a hundred bucks today. i still don't know poop about the mac or it's operating systems but i have a working machine. thanks to Rov and some other kool mac'ers i got some good links. anyone have a link to an upgrade site for my new unit. i will say this unit has just about everything in good working order. the battery works. it has a nice carry case. and a zip drive. i would like a cdrw and some more ram. would os9 or x run on it. has a 2 gig drive i believe. im just now figuring out how to access system info. any ideas on how to enter bios? thanks you all
