Welcome, don't know about any pdf docs as the original supplied was a folio-views file. If you have something that has been convert to pdf that is helpful. For the most part, this isn't much different than the earlier ML/EL type systems. Some may disagree, but it's all good. I find it best to use putty raw on port 2000, with the correct settings for admin as the web stuff is outdated and everything I need to do can be done from a terminal session. It is actual faster to do what may need to be done than the provided web pages IMHO. If using putty, I turn off the line discipline options, this makes it like programming an older 200 system be it ML/EL or Light/Digital system.
