Abstract
In a computer system, one or more ISA connector sockets is replaced by a connector structure which carries both ISA signals and local bus signals. The connector structure is arranged such that a standard ISA accessory card may be inserted, in which case only ISA signals are coupled to or from the card. "Local bus" accessory cards may also be designed for insertion into such a connector, and these cards may connect to one or more signal lines of the local bus either additionally or instead of connections made to the ISA bus. By physical or other means, ISA accessory cards are prevented from unintentional contact with connector contacts which are coupled to local bus signal lines. The connector structure may advantageously comprise an EISA-type connector socket.
