    From what I have seen of the EISA design used by big blue there are
alignment ridges that prevent the old style boards from contacting the extra
contacts down deeper. These samw ridges and the edges of the overall connector
should prevent the kind of problem you fear. The killer is going to be the
cost of these kind of "custom" connectors. Remember trying to finds a DB-23?

    Only time will tell what design they have choosen.
