Canon Palmtronic LD-81

The Canon Palmtronic LD-81 followed the original LD-80 and introduced a complete new and colourful design. The colour-coding of the keys – black for numbers, blue for functions and yellow for control – together with the silver keyboard plate and the dark housing gives a fresh and modern design. Compare it your own with the design style of the LE-84 or the odd LE-80R and LE-81 calculators.
