console login without CDs

[Wizard]

Ok, I just had someone hand me an Alpha 2100 4/233 without any CDs (or
anything other than the box, for that matter). I have a few questions:
1.> Are the peripherals standard (keyboard, monitor, mouse)? The ports look
standard. I can't get the Compaq/HP sites serial# search to work, so I
haven't been able to get the info from there.

2.> It has what looks like a standard IEC cord connector on the PS, but
there is no sticker (it may have been peeled - there are remnants). Any way
to tell if this is 120VAC other that trial and error (it's the 'error' I'm
worried about)?

3.> I'll need to boot single user, with no root password. Can I even do this
without the CD? I'm guessing that it's running OSF/1, but I did notice that
the filesys is listed on the outside of the box as BSDsomething, so I could
be wrong.

4.> It comes with 3 SCSI RZ28M-VA drives. Does anyone know what size these
are?

That's it. Any help would be appreciated.
