I can't find a Demo of that tiny stuff anywhere.
Really? I found several by searching for Tiny Tiny RSS demo
If you don't have time to install a copy yourself, then I'd say it closet resembles The Old Reader in terms of layout, but I find it much more usable.
all the documentation seems to indicate it's mostly just a reader.
Yes, Tiny Tiny RSS is an RSS reader where you host the reader and OPML yourself.
I just want my articles to store from 1 - 1000
If I understand you correctly then almost any RSS reader would do this.
For example, in Tiny Tiny RSS you can set your preferences to purge articles after a certain number of days, or not at all. You can also decide how many articles to display at once. The system paginates them for you.
