HP-12C / HP-12CP CPU stress test using date operation

[lvt]

As I use quite often the date function of my HP-12CP, I decided to make a little piece of code to test the calculator's real life durability.

The code will display dates from October 15, 1582 to November 25, 4046 (or 899,999 date operations) on the calculator's screen.

The test is expected to last at least a week and will required a new pair of CR2032 batteries (replaced one by one to keep it running).

The screen is set to maximum brightness (to take clear pictures from time to time).

The code :

Quote:1. 36
2. 42 6
3. 1
4. 43 16
5. 43 33 003
6. 43 33 000

Usage: DD.MMYYYY + R/S
