 Of course -- but I do think that the cost of retaining docs is minimal,
at least when compared to profits gained from the respective equipment. 
Upon the commercial end of life of some stuff an action of preserving docs
might be performed by the team that used to support it.  I don't think
putting docs somewhere on an FTP server takes more than a few days and
then hard drives are so cheap there is no point in not keeping such data
there forever.

 Actually I do understand it -- I've never been much enough inclined to
work on docs as opposed to making real stuff.  As long as they are not
handwritten notes on unsorted pieces of paper, but some sort of electronic
document, which I would expect to be the case these days, they are still
easily processable.

 I do not need a high quality docs -- I think anything that lets deduce
component's operation is much enough to make it useful.  And these bits
must be written somewhere anyway, as I wouldn't treat human's mind perfect
enough to be the only source of technical details.  It's much too

 Well, better late than never, but there is still plenty of excellent
equipment out there which loses against crappy old PCs because of lack of
