The PDP11 architecture manual says it's specific to the 11/70, and the 11/70 handbook
says it contains information "uniquely identifying each system" -- which
suggests that it contains a serial number or equivalent.
It's not clear what purpose it serves. RSTS (in the Init "Hardware List"
command) will display it but apart from that I don't see it used, which makes sense.

The occasional processor handbook says not implemented or the 11/xy reports num.
Interogative : information sources, e.g. a tabulation of known values
