Have you used your calculator for something that was not really math related?

The directions for the Moka pot say to run a medium heat and to turn the heat down before it starts gurgling at the end of the brew. So now, when making a pot, I turn the heat to 5. (I just noticed the stove dial goes to 11! ;-) It starts at LOW, then 1-9, and HIGH.) I then run a timer program on my 41-CX:

01 LBL 'MOKA
02 STOPSW
03 'HEAT=5: R/S
04 PROMPT
05 -0.0745
06 SETSW
07 RUNSW
08 END

When the countdown alarm sounds, I lower the heat and shortly thereafter the pot gently gurgles, indicating the coffee is ready. The coffee tastes better and the wife is happy!

You can use XYZALM instead, and then you won't be not taking the 20mA of battery current to run the stopwatch. Do something like:

Code:
.0745   \ (for 7 min, 45 sec)
TIME
HMS+
0
0
0
R↑
XYZALM

Then you can even turn the 41 off, and when the time comes, it will turn itself on and sound the alarm, which you clear with <shift>C.

It could be re-arranged to get rid of the roll-up instruction, but I have it in a subroutine so you start with the desired delay in X and call it.
