26   operating system this machine is likely to run.

29NOTE-START
30Sun 1, 2 and 3 (-machine=sun1, -machine=sun2, -machine=sun3;
31                -opsystem=bsd4-2 or -opsystem=sunos4)
32
33  Whether you should use sun1, sun2 or sun3 depends on the
34		   VERSION OF THE OPERATING SYSTEM
35  you have.  There are three machine types for different versions of
36  SunOS.  All are derived from Berkeley 4.2, meaning that you should
37  use -opsystem=bsd4-2.  Emacs 17 has run on all of them.  You will
38  need to use sun3 on Sun 2's running SunOS release 3.
39
40  For SunOS release 4 on a Sun 3, use -machine=sun3 and
41  -opsystem=sunos4.  See the file share-lib/SUNBUG for how to solve
42  problems caused by bugs in the "export" version of SunOS 4.
