This article reminded me of the hashing video (your first link). Somewhere else he claims 2/3 hash per day with paper and pencil.

I wonder if you can do these on that old HP calculator everybody loved (the 48, I think?) and how fast.

The HP48 is programmable and designed for scientific computation so I'd be astounded if someone hadn't already tried to mine coins on it.
