    Yes, exactly.  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).
