We were newly-weds, living in Sherman , TX. We watched all of it on our black & white console TV, and recorded the landing on a reel-to-reel tape recorder. I found that tape yesterday after watching some of the current coverage. I don't have a player any longer do I don't know the condition of that tape. But we both remember watching the landing. Really something.
The last 30 seconds or so of the landing has been shown on TV many times.
Here is the complete powered descent from the moment the lunar module engines are first fired to leave lunar orbit.
The 1201 and 1202 alarms called out during the descent are executive overflow alarms from the primitive computer.
The computer plotting trajectory couldn't keep up and was discarding other tasks with a lower priority.
