22 | operating system this machine is likely to run. |

24 | ||
25 | NOTE-START | |
26 | The vax (-machine=vax) runs zillions of different operating systems. | |
27 | ||
28 | Vax running Berkeley Unix (-opsystem=bsd4-1, -opsystem=bsd4-2 or | |
29 | -opsystem=bsd4-3) | |
30 | ||
31 | Works. | |
32 | ||
33 | Vax running Ultrix (-opsystem=bsd4-2) | |
34 | ||
35 | Works. See under Ultrix in share-lib/MACHINES for problems using X | |
36 | windows on Ultrix. | |
37 | ||
38 | Vax running System V rel 2 (-opsystem=usg5-2) | |
39 | ||
40 | 18.27 Works. | |
41 | ||
42 | Vax running System V rel 0 (-opsystem=usg5-0) | |
43 | ||
44 | Works as of 18.36. | |
45 | ||
46 | Vax running VMS (-opsystem=vms) | |
47 | ||
48 | 18.36 believed to work. Addition of features is necessary to make | |
49 | this Emacs version more usable. | |
