after using NetBSD 3.1.1 on this VAX 4000/200, I just thought it would be about time to do a plain reinstall using some cdrom with NetBSD 10.0 RC5, but at boot it couldn't "find any uba devices":
>>>init
>>>boot dua0
>> NetBSD/vax boot [1.12 (Tue Feb 27 05:27:39 UTC 2024)] <<
>> Press any key to abort autoboot 0
getdisklabel: no disk label
nfs_open: must mount first.
open netbsd.vax: No such file or directory
> boot netbsd
getdisklabel: no disk label
nfs_open: must mount first.
