It first ran on the IBM 704, whose index registers subtracted (as did the follow-on 709, 7090, etc), so array indexing went from higher memory addresses to lower.

The bookshelf: I had most of those books once; what's the one on the

I'm not sure, and things have shifted since then on the shelves, but I sent the original photo to your email address.
