In a world of smartphones and tablet devices, Hewlett-Packard’s 12c is a relic of the 1980s. An electronic device with one fundamental function: financial calculations. And, by today’s standards, not even a particularly sophisticated financial calculator.Yet this month, it is celebrating its 30th anniversary with a special “Platinum” edition. The company is coy about figures but it is estimated to sell tens of thousands of these $70 calculators every year. It has never been out of production.
