I had that slipcase too, but it got eaten by the dormouses that live under our rooftiles and who found a way into the room where I store my calculators. Fortunately they don't seem to like the type of cardboard from which HP makes it's calculator boxes.

By now even the corrections are no longer effective. But this only means that the ephemeris data stored inside the calculator can no longer be used. The calculations can still be done using tabulated figures from something like the nautical almanac.
