Several years ago, Hewlett-Packard made a calculator with a built-in stopwatch, and another calculator that was the same except for the stopwatch. Naturally the latter calculator was cheaper. However, by pressing an undocumented combination of buttons on the latter calculator, you could put it in the stopwatch mode that it wasn't supposed to have! Except that, regrettably, the cheaper one had only an R-C oscillator, but the expensive one was crystal controlled.
