Sounds like the monitor that I do my testing with :-/ I have to turn
off all the indoor lights and close the curtains to use it. The green is
very weak in it so the colors are distorted but like you, I only use it for
testing. the other possiblity is that now that you've found a monitor that
will do what you want, you can either pay to have it repaired or try to
find a good used one (E-bay?).

I don't know. I've been told that you can interrupt the boot process
and then start it up in single user mode and edit the password file but
I've NEVER been able to get one to go into single user mode. Frankly the
purpose of a password is to prevent people getting into the sytem and
simply hitting Control-C or whatever and getting into it via single user
sounds too simple to me. I can't believe that any decent system would allow
that. I have found some systems that I was able to get into using the
normal default passwords like "Root" and the like.

I get a LOT (make that a HELL OF A LOT!) of military surplus computers.
They usually wipe all the PC and MAC drives but almost never wipe the
drives on HPs and the like. I've not sure why but I think it's because the
people doing the surplussing don't understand how to set those systems up
or how to operate them. A ten year old can put a PC or MAC together.

Nothing that I'm aware of but I'm not an expert on HP-UX.
I do have a doc set for HP-UX 5.5.
