Need some help to bring up 4.2bsd, 4.3bsd or System V on a VAX 11/785.
The problem seems to be hardware related but not sure. 

After extraction of distribution mini-root we get a segmentation fault,
trap 8 with the system crashing.  We never get to the root prompt with
the current configuration.  What I am looking for is anybody running UNIX
on a VAX 11/785 and possible ideas or floppy configuration (defboo, boot,...)
that might help out in this situation (or do I really have a hardware problem).
Thanks for any help.
