Yes, this is what you should use. If you have the MC68881/882 User's
manual, section 13 gives the order numbers for the parts the NC can
use. Also, the 25Mhz won't do you much good. Due to the limited speed
of the bus for the II, the 25Mhz won't buy you much. I have a 16Mhz in
mine and that's probably overkill. The 12.5 or 16.67 should be
sufficient.
