When the 10811 was being designed, the prime directive was that it
had to be retrofittable into any 10544 socket.  (Note that the
converse is not necessarily true.)  Therefore you should be able
to install a 10811 in an old counter, if you have the infrastructure
that fitted the 10544.  IIRC, the 5342 came out in the 1970's before
the 10811.
