Try QSECOFR or QSYSOPR for the username with either the same thing as the
password or some other passwordy-type-thing. The remaining fields may
be left blank; they'll default to something reasonable.

Once you get in, you won't have a hard time getting around. The menus
aren't organized in the most intuitive way, but it's pretty simple to poke
about and find ways to modify accounts. By default, security management
is -all- QSECOFR can do, so you'll want to use that to pop open the
QSYSOPR or one of the system programmer accounts before you get to
actually play with the system.

Heh. You'll probably have an easier time finding QIC tapes. However, I
think the '170 has its OS keyed to the chassis ID, so you may want to see
if you can find the OS restore tapes from whomever sold you the system. I
have a '150, whose OS is -not- keyed (up until V5? I think?), so I was
able to order an OS/400 tape from some bloke in the UK via eBay.

I doubt it. These things are built to survive anything.

Do you know what release of OS/400 you have? It's likely V4R3 or later.
 Bear in mind the sort of suits that tend to own these things; the
QSECOFR password may be written on a label stuffed inside the chassis
