I dunno how you would go about making such a cable, but the connections are the same. I think Doug needs to add a few additional options to NET: to support more than two amigas, setting UNIT=2 will not work (it only checks 0, non-0 from what I understand) Three amigas will probably work but likely 4 will be unreliable... one would need to make a circuit board with real open collector drivers (use the same spec as IEEE-488 for line loading). -Matt >-- > -Bill Seymour ...tektronix!reed!percival!agora!billsey >============================================================================= >Bejed, Inc.
