Thanks, seems like a the checksum comes from a hidden roulette wheel program with 2^16 "checksum slots" for the ball to drop into. Super.

I so want to like this calculator, but such things drive me nuts. This has been in production for 12 years and some simple changes to the firmware would have fixed this and most of its other problems long ago (at least for the ones produced after that point).

The thread grsbanks supplied is from 2007. To not have a provision to implement running bug fixes is shameful. I'm not saying they needed to recall all the buggy ones (although that would have been nice), but when a bug is ID'd, it should be stamped out.
