[rescue] sm?1 vs sm?1-2

[Joshua D Boyd]

What is the difference between units like the sm51 and the sm51-2, or
the sm61 and sm61-2?

http://mbus.sunhelp.org/misc/sunparts.htm seems to indicate that the -2s 
can't be used in ss10s, 20s, or 4/600s.  Guess it is a good thing that I
got outbid on one then.

Still want a dual processor module though.  Appears like I'll end up with
an SM61 instead.
