Well, the new TI85 has a backup battery...

I hace a TI81 and like it.  Too many calculators are *SO* complex that
they are harder to use because you can't remember all the functions.
IMHO, the TI81 is a nice compromise between power and ease of use.

What I did was to buy a 6v lantern battery from a hardware store, along
with a couple of wires.  Being careful with the + and - , I did a
delecate "battery bypass" operation.  This allowed me to remove and
replace the AAAs in there without interrupting the power supply.
Look for the writeup on the delecate procedure in the next "Journal
of the American Calculator Medical ASsociation." :-)

Something else you could do is give a student a couple of extra credit
points to type out the programs inside so that if you flub the operation
and the patient "dies", you can re-enter without having to re-write.
