Indeed I have. Since the beginning, and every day since. I do have a lovely binder with IBM DOS 3.3 as well as recently acquired boring shrink wrap versions of MS-DOS 6.2 and 6.22. I used to have a bunch of those nice IBM binders a long time ago, but I didn't value them then and have no idea where they went. I wish I had them now.
I've also got some not too pristine Kaypro manuals and other miscellaneous stuff.
There was a NIB LOTUS 123 on a shelf in the basement, I noticed earlier. And there were some boxes of Red Hat 4.0 and 5.0 too (basically kept as ephemera and not software). So yes - I'm not completely out of the loop.
However, I don't really collect that stuff except as it's found at undefined and mysterious places. I certainly don't buy it. What I was hinting at earlier is that (outside of my original DOS) I've just used BBSs, later Simtelnet, and after that, it's been FOSS the whole way. No boxes.
I was also thinking that the words "DL, DL, and DL!", as written in the poll choices, seemed kind of loaded, and not really representative of "apt-get" or "pkg_add". Perhaps I read it wrong. Anyway, on Mars we use "make install clean".
