if they keep you from using some old chip you have lying around, you will buy a new one.

Nah, the developer who is looking for chips for his new design is not the only person who needs the datasheet.

And it's enough to put them into the "obsoletes" folder.

I believe it's much much more comfortable (from many points of view) for them not to keep the old datasheets and if I would manufacture chips I admit I would most probably do the same. Nevertheless, it annoys me (as a user - forced sometimes to debug/update old designs etc.etc.).

PS. As with the AT89Sxxx, in some areas the P89C51Rx2Hxx's are obviously still _sold_ although they are obsolete for years now; in the same areas I doubt you can get a P89V51Rx2...
