Nope. They go to a "feature connector" on the card. The signals brought
to that connector are all video ones, so it's my impression that the IBM
folks intended it either for mushing up into composite video or more likely
for various sorts of signal mixing with other video signals such as those
from an optical video disk. Never seen anything that actually attaches to
the connector, though.
