In the summer of 1975 Laurie Buxton, Staff Inspector for Mathematics for the Inner London Education Authority, obtained some development money to purchase 200 simple electronic calculators to use in a year’s experiment in schools. The machine chosen was the Citizen 120R, then the current recommendation to London schools as a four-function machine.
