Abacus
Abacus aka counting frame is being used in some places of the world, for example in Latvia.
Quite late introducing of electronic calculator to Latvia is only part of the reason.
Also Abacus is very stable and could be easy used by people with weak eyesight.
This one I found in Agenskalns pharmacy.

cool!
They really were the first calculators.
That's a really good documentary photo. There is so myuch information in it
Actually the abacus is better than a calculator - it needs no batteries and is as quick, if you can handle it.
