Ok, I was looking at some source in Assembly, and I saw some instructions that
I wasn't familiar with.  My assembler (Macro 68) assembles them just fine, and
they ARE mentioned in the 68000 manual, but just MENTIONED.  I have no idea
what they do.  If anyone can help me, so be it.
 
                st       (MemoryLocation)
                sne      d(n)
                sf
                sge
 
etc...
 
 These are not "documented" instructions.  What do they do, and why would
someone use them other than to save cycles or 10?  Are they also used on the
020 030 040 etc?
 
Thanks,
