68000 cross-assembler for sun4

[dupuy at cs.columbia.edu]

You should be able to use the Sun cross-compiler and specify that you want
to generate code for a sun2 (mc68010).  That will generate code which is
compatible with the 68000 (i.e. no bitfield insns, etc.).  The only
difference between the 68010 and 68000 are in a few supervisor mode
instructions which no sane compiler should ever emit.

If you really need a 68000-only assembler, you could use gas, the GNU
assembler - it's free, and available for anonymous FTP from AENAS.MIT.EDU
in pub/gnu.
