No comments? Well, I'll be the first.
I've noticed a few minor spelling and grammar errors in some of the latter logs, such as:
"A message not learned is a messagd not heard"
a slight ah, overreaction. he needed to remember her himself
Which I think can be cleaned up without breaking any contest rules.
Otherwise, I love this! This is a great companion piece to your tale and continues (and ends) Professor A.W.'s story adequately without simply expositing what happened. The people interviewed sound real and each one has a vibrant and memorable character. Your interpretation of dado is honestly refreshing, and his placement in the early 1900s feels natural. There's a lot of personality here, and even the more mundane sections (the descriptions of the anomalous machines) piqued my interest because their effects are unique. +1, and I'll say that this SCP is probably one of my favourite entries in the contest.
