> Of course, it never had power fail recovery (or battery backup) There's a 9-volt style battery connector hiding inside the little kangaroo pouch underneath the old chumby that is capable of powering the device but it was never officially supported and a standard 9-volt battery would not power the device for long enough to be useful in any realistic capacity. I do remember users hacking up their own battery packs with enough juice to keep it powered overnight but they tended to involve bulky external battery systems that kind of wrecked the overall vibe of the little leather ball.
