By the way - as far as newcomers go. I hope you are aware that the full 
manual set is available on bitsavers. It's a lot to read, but start with 
a few simple manuals like "Introduction to RSX", which is really basic. 
And then some manuals about utilities and system management.

Of course, you can also just ask, and I'll try and answer. :-)
