I don't have my Mac II here, so I try this from memory.  There are three
large (1" by 1") ICs placed on the center of the board.  You may have to
remove the drive bracket to see them.  One is the 68020, the second is
the 68881 and the third is the 68581.  The chips all are numbered.  If
you do not have the 68581 (PMU), it is replaced with an Apple chip that
provides a standard mapping (details in Macintosh Hardware Reference Manual
available in Beta form from APDA).  In my machine, the 68020 and the '881
are black with a gold cover, the Apple chip is all black.
