It's funny that the personified user interface is used as the title, because the star of the show is something much more hidden - one of the first multitasking "operating systems" correctly handling, and limiting the impact of, an unforeseen CPU-hungry process in the midst of the first moon landing! The OP's a fascinating read and more technical than the title might imply. For anyone interested in the process of compiling and loading the code for these systems (available at https://github.com/chrislgarry/Apollo-11/ https://github.com/chrislgarry/Apollo-11/ ) into the "core rope memory" used for program storage in the capsules, here's one of the original spec documents, as well as an image from that document showing what I'd call a "compilation-bureaucracy-pipeline" that's a fascinating glimpse into software deployment practices. https://www.ibiblio.org/apollo/Documents/HSI-208496.pdf https://www.ibiblio.org/apollo/Documents/HSI-208496.pdf https://imgur.com/a/wBYt1o6 https://imgur.com/a/wBYt1o6
