No. As far as I know there were only 2 11/74’s in use; the quad machine in Spit Brook (CASTOR:: and, when split into 2 duals the other was POLLUX::) and a dual in Tewksbury, later LKG (ELROND::). After the project was cancelled there were a number of already built 11/74’s which were stripped down to single CPUs and made available internally for development - that may be what you saw in the RSTS lab.
