alt Hacker NewsManuals used to have tens of pages of useful information, if not more. These days it's just tens, if not a hundred pages of (mostly meaningless) warnings, in different languages, and sometimes only that. If you're lucky there's a single page of mostly pictures and a few lines of text, and typically just the obvious parts. I went through some old storage boxes yesterday. Found "manuals" for a number of items. One had four manuals. Turned out it was just that they could only stuff half a dozen languages of warnings in one manual, so they made a bunch of them, all just the same warnings, in different languages. More paper for the recycling centre.
I particularly miss the spec page that used to be standard in every manual and is now increasingly rare.
Of course, the really old/good manuals also had schematics, and there were a few cases where those were really help when we actually had to repair stuff like that. For some simpler things that would make sense even today but it ain't happening...
