Hm, overviews could be of greater historic interest. I used google and 
it seems that my docs belong to a paper making machine control system. 
And it seems that those are still around somewhere.

What you get from technicians in most cases is not what gives you the 
"big picture" of a system rather than drowns you in detail.
For the paper thing, I have binders and binders and binders full of 
flowchart diagrams, listings, more diagrams, ECOs, memos etc.
But I have not yet found the machine's design documents or something 
that gives me an overview.

My (little) experience would say: Not really.

Yes. What is a pile of paper worth? If it's sitting somewhere at 
someone's shelf, it's inaccessible. And when that one once 
deceases/loses interest, it again endangered by recycling facilities.

Oh, a powerful document scanner seems to be a must-have! That would make 
things much easier.

Ok. That's a word.

That's difficult: I assume that my view could be to limited to see all 
implications. So it is possible that I or <someone else> just discards 
stuff that others would have killed for.

See the Kiel PDP10 docs I mentioned: They were on their way to the 
dumpster, decision made by an academic person working as scientific 
director. He did not consider the stuff worth keeping. Was he right?
Erik Brens walked along in the right moment, taking it all, finding 
people who are willing to pay $$ for it. So the (historic) value can be 
considerd a difficult to measure thing.
