My cousin told me about a related incident that happened which he was an Engineering undergrad. At this particular school, the engineers and the agriculture students ("agros") were constantly at war. At one point, some agros having fun with a fire hose decided to squirt some water in the window of an engineering classroom. There was a lab in progress with calculators all over the place. After the dust had settled and financial liability had been agreed, it developed that most of the non-HP calculators were ruined, while the HP's survived fine. The local HP man did recommend that the keypads be taken apart and cleaned, but that was a lesser issue. The spill shield that HP puts in behind its keypads had kept the insides dry. Note that the spill shield is designed to protect against spills, not against total immersion of the calculator. Not even HP calculators are totally waterproof, and once water actually gets into the insides of a calculator I suspect it doesn't much matter who built it.

When I was an undergraduate, my lab partner and I were working late on a Saturday night on one of our EE electronics projects. As we were finishing up (at around 1:30am) we noticed it was beginning to rain. We hastily gathered our paraphenalia and made a frantic 1/2 mile dash back to the dorm, where we collapsed soaked and burnt out. The next morning I happened by my desk and noticed my calculator was missing. A thorough check of the apartment turned up nothing, and I faintly recalled not having it when I got in the night before. I hurredly threw on some clothes and retraced my steps back to the EE building. Nothing! I looked everywhere, including the lab we'd been working in, and found nothing. While posting a lost-and-found note on the board in the student lounge, I was approached by a graduate student who said he'd found a calculator like mine just that morning, and would return it if I could produce the serial number as proof. I did so, and we went to his office so I could recover it. On the way, he told me that he'd been on his way in around 8:00am and had chanced to spot what he figured was an empty calculator case submerged in a fairly deep puddle. Absent mindedly, he kicked the case out of the puddle, and was greatly surprised to find the calculator still in it. Apparently, my calculator had spent the night soaking in the puddle! After a disassembly and good drying, I put the calculator back together, hooked in the AC adaptor and turned it on. Miracle of miracle, it worked! And it continues to do so to this very day (5 years later). The clincher? It's a Texas Instrument SR-50.
