I have a handheld calculator but it's in a drawer. An HP 35, the first scientific calculator ever made, the first run. Found it in the Black Hole for $5 years ago. See my brother had pre-ordered one but it was delayed because the US federal government acquired all the first run, for use at Los Alamos National Labs. That's where the Black Hole was, a surplus store for lab equipment. \ The faceplate has the key symbols silkscreened on it, instead of on the keys. That's how I know it's one of the first run. Kind of historic, if you're into tech history. Anyway, the NiCad battery pack gave up years ago.
