OK I have seen both on Panels pdp-11 and pdp 11/20
figured the first issuance would say pdp-11 only on panel

I wonder if the pdp-11 was just called pdp-11 at t that point or
was a pdp-11/20 like we have..
At that time PDP-11 was a general
architecture name and 11/mumble was a
specific system.
Keep in mind that new versions of the -11 would evolve soon after
introduction and
continue over time for decades.
Add to that there were both processor naming and system configuration
naming
conventions.
I know they are essentially the same at this time
point they got
their PDP 11 what did it say on the front panel I wonder?
(figuring all this stuff out for titling up the cards in the 11/20
display we are planning.)
Find a copy of the PDP-11 systems handbook! Say 1978, 80 and 82
versions and
see the difference. Never mind the Unibus, Qbus, PRO, and PDT flavors.
