Sumlock ANITA calculator £50,000 GBP but to be competitive with mechanical calculators the target selling price of the electronic calculator was in the range £350 to £400. The first all-electronic prototype was demonstrated to the board of the company in December 1958. This prototype was later donated by the company to the Science Museum in London, where Kitz had originally had the idea for the electronic calculator. It has been on display surrounded by the mechanical calculators that it was to make obsolete.
