Before the typewriter collection, in the early 2000s there was the calculator collection. I built up quite a collection of the little machines, some of which you can see in this series. For a change i decided to buy a new (old) calculator last week, the first for years. That machine is this Litton Imperial 1260 which may date from July 1976 (it has a sticker with this written on it on the base anyway).
The calculator is AC mains powered and to my surprise does power up. It can't perform any calculations though unfortunately, maybe due to some bit rot in the calculator's CPU.
