i would hook local talk cable up to both, then, use a boot cd boot the one you want the stuff copied to, use drive set up and wipe the drive, then, chooser click the other machine and just drag and drop, it may take a while, let it go over night. i just do a drag and drop with my vintage mac's all the time. then wala you will have 2 HD Booting machines with the same contents.

*edit* i'm not sure i wonder if you could use a ethernet cable… should work… might have to set some manual IP's not sure if the wallstreet has a auto switching port that will cross over… if not then you would need a cross over cable. would speed the copy up immensely

but i like like local talk, slow but very reliable and it just works!
