Help with PDP-11/04 Front Panel

I am supposed to go a look at a very old PDP-11/04 this
week and would appreciate some help as to how the front
panel is set up. Mainly, I want to be able to look at the
program that was loaded using hardware ODT, that is
just examine the program and confirm that it is the same
as a listing that I will have on a laptop which I will bring along.
I don't have to verify all 20 KBytes of the program, just
look at it ever 1000 octal bytes to verify that it is the same
at about 20 locations.

I doubt if this information makes any difference, but I
have been told it operates with paper tape, has core
memory and an ASR-33 as the console device. Also,
the program is stand alone (obviously since it has no
disk drives).

Mainly, I just want to press the HALT switch or button.
Then I want to look at memory via hardware ODT, then
restart the system without changing anything at all.

Is this possible? I know how to do it on an 11/73. And
I used to be able to do in on an 11/34.

Sincerely yours,

Jerome Fine
