This is not actually my question, I'm just posting it for a colleague of mine. Here is what he asked at work: "My home computer is a Power Mac 5200 or so. It is over ten years old and running well, but it has no internet capabilities. I would like to communicate with my iBook G4 to copy files, back up my old hard drive, etc.. I bought a card of some sort from Bob Overkamp that allowed me to connect to my last school computer, which I think was a G3 running OS 9, via an ethernet cable. I have had no success with my G4, which is running OS X. I have tried turning on file sharing on both computers but can't get a connection. The G4 does not show up on the Power Mac's Chooser, and the Power Mac does not show up on the G4's Connect to Server. Any ideas? Thanks." Just thought I'd throw this out there, see if anybody can help.
