As I recall from experience upgrading a Cube from a 68030 to a 68040
CPU board, NS 1.0a and earlier would not boot on the 68040. They were
written without knowledge of the future differences between a 68040 and
a 68030, which are significant at the system stack level. Just something
to think about.

This does not prevent user-level software from running, just system stuff.
