I used that PDP-1 at MIT in 1972 or so for the 6.273 programming course.
Still have my class notebook, with all my programs printed out on the Flexowriter terminals.
That PDP-1 was not a 'virgin' PDP-1 any more even then, it had features added by eager grad students.
As indicated above the second / backup that CHM has would be a better choice to restore.
