I *think* it's an RD53. I have never seen one before, but that's what I
believe it to be. It's not an RD54... smaller than that.

That would be my first thought, except that I have nothing that will boot
any PDP except for that disk. :) Of course, if anyone can supply media for
RSX-11, RT-11, RSTS/E or something else, that would be an option.

It is my understanding that RSX (except possibly RSX-11S) uses
FILES-11/ODS1, to which I have recently acquired the specification.

That is my thought. Either a startup command file, or a UAF file.

It is, and I've made a habit of switching the write-protect button every
time I try something strange. Don't want to loose my only copy of the
system software.
