Yes i guess you could say that the vxt.sys is a kind of VMS file. It's a
sort of standalone VMS binary. I've seen somewhere that DEC used to have
some kind of kit that you could use to build standalone software for the
VAX platform, that could be used for all kind of network appliances.

You should be able to break in to the system if you boot single-user.
# Boot into single user mode
boot -f rz(0,0,0)vmunix			# on 2100, 3100
boot 5/rz0/vmunix			# on 5000/200
boot 3/rz0/vmunix			# on all other models

If that doesn't work, you could also remove the root disk from the box,
and mount it on another system. If my memory doesn't fail, there are
copies of empty password and other config files left from the
install on most systems. They shouldn't be too hard to find. Since ultrix
doesn't use password shadowing copying the passwd file should "just work".
