It is a full 68040 with MMU and FPU. Indicative of crippeled versions
are the letters EC (no/disabled MMU) or LC (no/disabled FPU) between
the "68" and the "040". XC means it is a pre-series example, but I am
not sure if final (MC...) Versions of the 68040 have ever been
built. All I've seen so far were XC.
The other letters indicate temperature specifications, clock speed
(the 25, of course) manufacturing process details and other things I

Yes, NetBSD will run fine on it.
