Now that it has been explained in detail, I see the simplicity of it! Thank you!

But to help others, here's a more foolproof code listing:

P/R (exits Program Mode)
R/S (Run Program and displays "running" for at least 21 minutes on 12C variants and displays 876.00 when finished.)

My HP-12CP completed the program in 23 min. 14s.

Of course, now that I have done this, I see the 50g executes it in about the same amount of time, while the older 48GX does it about as fast as the Prime, making this speed test not much of a real-world test of speed among these specific calculators.

What I was hoping for was a typical yet complex calculation that could be done on the 12CP, 50g, 48GX and Prime to show the expected differences in processor speed; namely, that the Prime is fastest, followed by the 50g, and then the 12CP and ending with the 48GX. But it seems nobody has any ideas on that, so I guess I will give up on that idea. What I can say in my video is, "if you want to keep your 12CP running for 23 minutes, here's how to do it."

I still would appreciate knowing why there is an orange "OFF" label silkscreened above the ON button on the 12CP even though there is no need to press f and then ON to turn it off like other HP calculators. You just press ON once to turn it on and then press ON again to turn it off. Why then the orange "OFF" mark?
