The manual (EK-RKV11-OP-001) says: "Since the 11/03 BUS structure has no
provision for extended addressing, no connection is made to the bus from
these [XM] bits on the RKVII-D." (pg. 3-5).

Interesting. Where did you see that listed, just out of curiosity? (I looked
in the Jan '84 PDP-11 Systems and Options, my copy of which just showed up,but
that's too late; I could probably find it if I pawed through all my DEC sales
literature, but I'm too lazy... :-).
