        Yes, as did the MicroVAX I. But IIRC it was with the
        MicroVAX II that the architecture was formally
        subsetted.

        Hopefully about the same, othewise they did
        a poor job of selecting instructions to subset!
        The instructions that they did not implement
        were those that were infrequently used and
        cost too much chip real-estate.
