27 NOTE-START
28 The vax (-machine=vax) runs zillions of different operating systems.
29
30 Vax running Berkeley Unix (-opsystem=bsd4-1, -opsystem=bsd4-2 or
31 -opsystem=bsd4-3)
32
33 Works.
34
35 Vax running Ultrix (-opsystem=bsd4-2)
36
37 Works. See under Ultrix in share-lib/MACHINES for problems using X
38 windows on Ultrix.
39
40 Vax running System V rel 2 (-opsystem=usg5-2)
41
42 18.27 Works.
43
44 Vax running System V rel 0 (-opsystem=usg5-0)
45
46 Works as of 18.36.
47
48 Vax running VMS (-opsystem=vms)
49
50 18.36 believed to work. Addition of features is necessary to make
51 this Emacs version more usable.
