It's an 11/93 all right.  It has 2 meg on the board.  The chips are 
surface mount
and even if I could find some I could trust were good (all I saw with a 
quick search
were "refurbished" which means taken out of something else!) I am not 
sure I would
want to risk working on what I consider a rare find and my best PDP-11.  
I have found so far says PMI works fine so I would prefer to find a 2meg 
or even a
pair of 1 meg PMI boards.  Not looking at commercial resellers because I 
have dealt
with them in the past and know I can't afford them.
