The following is actually Qbus...

>DECsystem 5500 (KN220), MIPS R3000 with FPU
>Unibus expansion architecture
>Prestoserve NFS caching hardware
>3 x MS220 RAM expansion boards and onboard RAM totalling 128 MB
>3 x RZ57 (1 GB) DEC SCSI hard drives
>4 x RA92 (1.4 GB) DEC MSCP hard drives in an external
>  free-standing SDI/3 High Expansion case
>DEC TK70 tape drive connected via DEC TQK70 Unibus tape controller
>DEC VT320 console and cabling
>ULTRIX 4.5 pre-installed
>
>Cost: Shipping costs only (this is a fairly large system, and the
>shipping costs are non-negligible).

That config would allow most of the VAX Qbus drivers to be
reused without having to worry local DSSI disks.  The only
thing that would be required is a SGEC Ethernet driver.
And with the a DELQA that could be avoided.
