Interesting, Copyright 1976 edition here, no other printing dates.
There is no page 17-44 in this edition.
I guess somebody observed an error in this edition and corrected it, or
perhaps Fairchild's preliminary design hope didn't make it to
production.
A little arcania..
I wonder if you have a later printing of Volume
II than I have here. I
do see near the beginning it states the 9440 implements only 'the LCD
of Nova features', but on page 17-20 in the instruction table there
are X's for the M/D instructions in the 9440 column. On page 17-15 it
says X in the column indicates the instruction is present. The stack
operations listed next have no X, indicating they are missing on the
9440.
I'm working from the June, 1977 edition. In this one, it's on page 17-
44 and there are no "x" marks in the 9440 column for MPY and DIV.
