DEC only ever supported a single RP07 in a structure, or up to 4 RP06s.
There was a Stanford hack which allowed up to 4 RP07s in a single structure,
but MRC disliked that for the Panda distribution and eliminated it from his
monitor.
We used it at Stanford LOTS to create a PS: that resided on 3 RA81s on the CI,
so that no matter which system a student logged into (Lear, Othello, Hamlet, or
Macbeth)*, they had access to the same directory.
[*] Lear was the original LOTS machine. When a second came along, it was
crowned "LESS"; a third brought about a renaming, and they became LOTS-A,
LOTS-B, and LOTS-C. When the SC-30M came on board, it was named "Epic",
but a great renaming took place in which all Unix workstations and the
mainframes were all named for Shakespearean characters (to avoid calling
the new system "LOTS-D"). The CI came along at the same time, allowing for
a single-system-image style login.
