The A-1000 is one of the very first electronic programmable calculators. (The Casio Company claims it is the first). It is a desk-top calculator that uses transistor electronics, ferrite core memory and Nixie tubes for numeric display. While its applications were restricted to mathematical calculation it anticipates the arrival of personal computing.
