yeah, eventually, but in 01976 uucp was just getting started. even in 01978 i don't think they had a well-defined network map, though they said uucp already connected over 100 unix machines in the 7th edition manual. that post is from 01981
unfortunately 'show original message' is grayed out, so i can't actually see the map
