Ok, i'm getting an old iMac g3 today and i don't have a router. My cable modem has 2 outputs, one eithernet and usb 2. When i get it home and set up can i network with my windoze machine with out a router? My pc will be on the usb and i'll hookup the mac to eithernet. Both output ports work at the same time. thanks for all the help!!
