13 operating system this machine is likely to run.
17 Sun 1, 2 and 3 (-machine=sun1, -machine=sun2, -machine=sun3;

20 Whether you should use sun1, sun2 or sun3 depends on the
21 VERSION OF THE OPERATING SYSTEM
22 you have. There are three machine types for different versions of
23 SunOS. All are derived from Berkeley 4.2, meaning that you should
24 use -opsystem=bsd4-2. Emacs 17 has run on all of them. You will
25 need to use sun3 on Sun 2's running SunOS release 3.
27 For SunOS release 4 on a Sun 3, use -machine=sun3 and
28 -opsystem=sunos4. See the file share-lib/SUNBUG for how to solve
29 problems caused by bugs in the "export" version of SunOS 4.
