I've scanned another of my slide rules (holy Crap that takes a long time), this time the Pickett N525-ES StatRule. I was sort of disappointed with my StatRule. I thought it would be more "powerful" and capable of amazing statistical calculations, but it can do only basic things. Oh well. I'm not sure what I was expecting -- after all, it is just some pieces of metal sliding along each other.
As I was working on this one, I was thinking, "gee, at what point does collecting become an obsession, and when does that obsession turn into utter batshit insanity?" (That was just a random hypothetical thought of course, totally unrelated to slide rules.)
