22 operating system this machine is likely to run.
23 USUAL-OPSYS="note"
25 NOTE-START
26 The vax (-machine=vax) runs zillions of different operating systems.
28 Vax running Berkeley Unix (-opsystem=bsd4-1, -opsystem=bsd4-2 or
29 -opsystem=bsd4-3)
31 Works.
33 Vax running Ultrix (-opsystem=bsd4-2)
35 Works. See under Ultrix in share-lib/MACHINES for problems using X
36 windows on Ultrix.
38 Vax running System V rel 2 (-opsystem=usg5-2)
40 18.27 Works.
42 Vax running System V rel 0 (-opsystem=usg5-0)
44 Works as of 18.36.
46 Vax running VMS (-opsystem=vms)
48 18.36 believed to work. Addition of features is necessary to make
49 this Emacs version more usable.
