    The difference about using a memory cap in a WPC machine is that in addition to preserving the memory it also has to support the real time clock, so the power draw is greater. I've heard of people getting 2+ weeks with a memory cap and WPC which is probably ok for a collector who plays their game sporadically.

    Unless your game has a midnight madness mode or you are so fastidious that your machine has to have the correct date and time, you're better off putting in a NVRAM solution IMHO.

    Quoted from thedefog:

    For $3.91 per cap on mouser, you can't really go wrong. Viper, have you by any chance experimented with higher value super capacitors than 1.5F? I see 5F caps there for around $10, I'd imagine they'd last more than twice as long, with the discharge rate being the same?

    No I haven't. There are apparently issues with initial current inrush on an empty supercapacitor and the circuit on the CPU board may not support this. Unless someone like Ed @ GPE or someone else who has experience with supercapacitors can chime in here to the contrary, I personally wouldn't try it.

    Makes sense. Thanks for posting!
