You can _picture_ it, but would you _do_ it? I hope not. While the ostensible addressing limit of a LocalTalk net is 254 devices, the bandwidth maxes out at about 50 (presuming PhoneNET - it usually dies quicker on Apple hardware). So, you could have a Star Controller with 10 1-machine ports, 1 branch each, and 1 port with 35 machines distributed across four branches, and one port with a bridge or gateway to get you the rest of your net. You really shouldn't try to cram more than about 50 devices onto your LocalTalk net. I assume you're not going to try to support more than one net per Star Controller. More typical is an even distribution of machines across ports, with things like gateways given their very own port. Another helpful hint from blackey douglas, tech support, farallon computing. -- josefk@well.sf.ca.us {apple,hoptoad,hplabs}!well!josefk Dissemination: the upside of entropy
