++% Used by a free user in the Library of Congress. Apparently this is used to
++% draw a partial page, which is then filled in by the results of a barcode
++% scanner and SQL database lookup. Its not clear to us exactly why this needs to be
++% done as a partial page, but its easiest to restore the operator, and it seems like
++% its a reasonably safe operator to restore, for the *very* few devices on which
++% it will have any effect. Currently this uses the 'sync_outptu' device method
++% to transfer the partial page, in future we may use a spec_op instead.
