As other people on the list have mentioned this really isn't a
VAX, even though it is labeled that way. Its a MIPS R3000
based workstation. At the time these workstations came out
a number of the Dec naming schemes were a bit confusing, and
quite often the same hardware was labeled differently depending
upon the software it ran.
What you have sounds like a Decstation 5000/200. This is a
nice R3000 based workstation, though it sounds like the configuration
of your system is somewhat minimal.

Your system is trying to boot Ultrix (the dec version of Unix) and
it can't find the kernel. There are two common reasons for this.
First, there isn't a disk on your system, or the disk with Ultrix
is missing. It wasn't uncommon for the 5000/200 workstations to
not have an internal disk, they quite often had a second chassis
with disk and/or TK50 tape. The other possibility is the version
of Ultrix on your disk is corrupt.
First check to see if there is a disk (open up the box, take
a look). Also check what your system thinks is attached to it.
There is a command for this that you can enter at the >> prompt.
I don't remember the name now, but type help at the >> prompt
at it should tell you. This will tell you the devices attached
to the SCSI interface so you can determine whether it is looking
at the right drive.

It will have a keyboard connector, it will probably look like a RJ11
phone jack if I remember correctly. There should also be a video
connector on the back. The video connector has 3 pins, its doesn't
look like a VGA connector, or any other standard video connector.
The three pins are R,G,B with I believe sync on G. You should be
able to connect these to a VGA monitor.
You can also interface the SCSI version of the TK50 and the RRD40
CDROM to these boxes. You can occassionally find parts for these
workstations on eBay, and there's a surplus place near Montreal
that sometimes has parts as well.
They make a decent Unix workstation. I used a 5000/20 at work
for many years, and I have two 5000/20 and a 5000/200 at home.
