First, this thread is fascinating, thank you to everyone providing this 
great history.

John,

Could you elaborate on what tests were performed at the time to call it 
secure? I am curious to compare what type of standards and/or testing was 
performed, as compared to modern designations of 'secure' (e.g. via audit, 
compliance, pentesting, etc.).

I am a 'vulnerability historian' of sorts, so this is a rare time 
something is squarely in my niche. =)

Thank you!
