HP41CL Weird behavior

[Neve]

Hi all,

I’m getting a strange behavior from my 41CL V5.

Here is what I have currently installed in it:

YFNP 1L
PWRL 1U
Time Module 2
41AD 2
SM44 3
Card Reader
STAT 4U
Also “804040-8120” YPOKE

As mentioned in another thread, I now have 218 registers instead of 219. It appears to be normal and to be expected.

However, what is not normal, at least to me, is that whenever I turn off the calculator, and turn it back on, no matter what was in LASTx disappears, and it always returns: 0.0025 -67

No matter what I do, it’s always the same.

Is this a bug?

Calculator has the latest updates installed: rom_files_180223

Thanks for your insights.
