It happens once in a blue moon, but it's possible.
I used to have it happen to just about every other file.
Just putting it out there...

Ah ok, then I guess I'll retry. Keep in mind this 83+SE had problems before, such as battery power being drained in one day even if the calc is turned OFF and with a brand new lithium battery.

Not much lately. I got Save As... working. Eventually I'll get some better AI, but I'm pretty busy/lazy right now with track.

You can build a statue out of either 1'x1' blocks or 12'x12' blocks. The 1'x1' blocks will take a lot longer, but the final product is worth it.

Slight AI problem, and a reason why one-turn value evaluation isn't necessarily the best option:

In the early game, you can get your queen out in the open, and the AI always tries to capture it by using his knights and bishops (often placing them in danger of, say, my pawns). One-turn value evaluation sees this as good, because its potential gain (+9) far offsets its potential (actually probable) loss (-3). This also creates a largely offensive-based AI, where the AI ignores defense almost entirely.

(Also, this pretty much rules out the AI from ever sacrificing material)

Nevertheless, I'd say that the AI can't get much smarter without pulling some computational feats that surpasses the speed of the processor :P, so still pretty impressive. Just throwing out some cases where the AI can potentially become even better :D

Maybe it can put in a check where if it moves a piece into a spot that can be attacked, any points that the piece could take would be ignored.  Like if it saw moving the night could put it into danger, it would ignore that it could also threaten the queen because it would know that it would not be able to carry out the capture

How is the AI? I'm not good at chess at all, so I can't tell.

There was no way to set how hard/bad it is but it was quite good. I think I won the only time I played.

The AI works. Perfectly. Never seen an 83+ series chess program with AI before :D
However, as penguin77 himself has stated and the rest of us have agreed, it is rather awful :P
Sadly, it can't get much better without becoming horribly slow, and it's already somewhat slow as it is :/
Regardless, it is a great achievement and we'll keep looking for ways to improve the program :)
For me, personally, I always beat it, and I don't even consider myself that good of a player :P

It's a calculator, for a calculator, it is damn great, but when compared to other Chess games, then we can say it's not so good.

I agree. That reminds me... I should really post a news about this at one point, although maybe another staff did before.

Good idea, it does deserve a news topic.
