  However LSI-11/23 whatever that is, typo? 
No, that's exactly what's in the manual I cited; as you say, though:

...
  That always had me during my yeas at DEC going which
one are you
 talking about, as every thing had at least three names (never
 minding numbers) and one was usually ambiguous or a nonspecific
 family name. 
DEC's naming of systems always drove me wild. To me, the worst one is the
lack of a name for a system including a KDJ11-A; as someone here pointed
out, the name "-11/73" is properly only applied to systems with a KDJ11-B
and no PMI memory. As I understand it, DEC apparently didn't sell
KDJ11-A's in complete, new, systems (it was just an upgrade board), so no
number was ever allocated.
