Trying to network G3 to Performa 6400 via AppleTalk. Performa does not display in the Chooser. Have turned on AppleTalk both machines, LocalTalk adaptor plugged into G3 printer port, 2 phone cables from there to: Performa 6400 (adaptor there has terminator and 9-pin plugged into printer port) and other to Laser printer and again terminated. File sharing is on and both computers have owner name, password and computer name. Am I missing something?
