Looks like my message got lost in the aether. Apologies if this
resembles something you have already received:

Yes, this is one of those Celestaire things mentioned above.

And I afraid that it consumes power like my stupid laptop,
which converts all this power to heat so that it is painful
to keep it on my laps:-) And accordingly, the super-powerful battery
hardly lasts more than 1 hour.
Alex - If Ken listed a weight of 3 pounds in the Celestaire catalog, it was
shipping weight. My TI 89 with snap cover (all about 5 - 6 years old)
weighs about 264 grams with batteries (batteries account for ~ 100 grams of the
264), and battery life (4 ea. AA batteries) by my poor memory is somewhere above
one hundred hours - maybe several hundred. But the capability is an
order-of-magnitudes leap from an fx-250 or 260. The text on my 89 was
inconveniently small, and the StarPilot program increases the characters to a
comfortably readable size.
