David, Those drives are safe at my house, the museum seemed to have no interest in them since if they planned to get any machines going they planned to run some of your boards and not original drives even if they did work. Glad to see you were able to get the head amp board hooked up to one of these. We should be-able to recover what was on the original drives.
I have not attempted anything with them myself but I have one of your boards I plan to build up with a future digikey order. I have been working on some new boards I designed I need to get up and going not related to vintage computing. The next time I am at the museum I can drop them off somewhere so you can look at them if you'd like.
I believe I was not able to get MOP booting working on the Vax... I believe it was an issue with it being a Microvax II. I really ought to drag my Microvax II up and see if I can attempt to get it net booting. I have only gotten later Vaxen going with my MOP boot setup. Specifically a 3900 and some 3100s.

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?
