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
