It's not an MC1711L based on that pinout.  (But I suspect as you do that
it's part of the sense amp for the core).  In particular Pin 1 of the IC is
connected to what I believe to be +15V.  (It's also hard to tell what pin 1
is, since there's no orientation marker on these... )  Ground is pin 10.  I
suspect -15V is pin 7.
