There have been a few auctions on ebay lately for the hp 21s calc and I happened to win one. The calc came without the manual however, and I noticed the other recent 21s auctions didn't offer manuals either.
I get the impression that these manuals are very scarce (the museum CD set doesn't have it). Somebody even put an add in the classified ads section of this site looking for it, and I ended up asking him if he had received it, and if he had and it happened to be in pdf format, could he mail a copy to me. Unfortunately, he hadn't so far gotten any response.
So, what's with these 21s manuals? Does anybody know where or how to get one?
