   I had gotten a RD54 and worked out how to pull the head servo for data
recovery.

At a previous workday a VAX was being worked on for the Museum. The drive in 
it had head position errors so I wasn't able to get a good read at the time.
With the above method I probably can read it now. If the drive is still around
and not reformatted I can try at the next work day. I think their was another
drive that wasn't read from a PDP-11 also.

Did the VAX get a new OS install on it?
