Hi Mac128,
Yes, I would connect the capacitor the way you've described (+ to +, - to -), just as if it were a battery. Just make sure that the capacitor is rated for at least 5V (5.5V is a common figure), and hopefully it will work. If you actually run this experiment, I would love to hear how long it holds settings. I am only guessing that the current draw is of the same order as a wristwatch (range of a few microamperes), so it would be nice to have some hard data instead.
