Booting PWB Unix1.0 to single user

[Quentin Fennessy]

I previously asked:

>I thought it ran only RSX, but I found an old Unix manual with it. I have been

Well, it has booted, but not to single user. Unfortunately all passwords
are history, and all I get is login:

When the machine boots, it says something like:
rc 1.5 booting pwbe0604 to multi-user
and then runs fsck on the system disk. It finds one file system corrupt,
tells me to find the sysadmin, and tells me to press HALT.
At this point everything I type is merely echoed. If I type <DEL>,
I get a login prompt. I cannot get this to singleuser.

If anyone can help me, I would really appreciate it.

Thanks a lot for your help. Email is best, and if there is interest I will
document my progress for the net.
