Question regarding a VAXstation - test-drb@ccmp.vtda.org

25 Mar 1999

...
 I have a VAXstation 4000/60 sitting in front of me.  I
have
been told that this ran ok about 8 years ago; I really don't
know if this fits the topic of the list (I guess it could
be slightly newer than 10 years).  The thing is, it
won't boot.  When it is turned on, it flashes several colors
on the monitor, it tests its 16M  of RAM and then it aborts
and dumps me to some sort of monitor program.  This is what
the screen shows:

...
 Only device number 3, "DZ" seems to be
faulty, and is the same
device appearing in the original error.  What is this device? 
The DZ is programatically similar to the DZ for UNIBUS and the
DZQ/DZV for Qbus.  It is a multiple asynchronous serial line
multiplexor (I don't know how many lines on Vaxstations...)

I'm not familiar with the 4000/60... but if it is anything
like other Vaxstations... the DZ is usually connected to the
keyboard and the mouse.  If you don't have these, then it
may report an error (missing the mouse may be enough).
