Agreed; I neglected to mention that mine also is marked in that manner!
Seems like DEC had ramped up to about 15-20 machines/day by mid-September.
Guess that the front panel graphics guys "didn't yet get the memo". Or
maybe someone was hedging their bets against an ignominious sales failure in
the initial front panel production?

Our PDP-11 is labeled as "S-308", the date is 9/16/70. And I think they
called it PDP11-20 from the beginning, as the model number above the serial
number says "M11-20"
