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.

PWRL is doing it. I don't know why. 'Angel?

It's been a long while since I did PWRL, I'll need to look at the CALC_ON code - this may be a simple glitch. I seem to remember I used register L for some scratch.

I'll get back to you when I find something. In the meantime, do you have any reason not to move to YFNX and PWRX?

Thanks.

No, no particular reasons. I just followed this I found online: https://www.thecalculatorstore.com/Calcu...em-solving

BTW, I’m very new to the CL. Should I put YFNX in 1L and PWRX in 1U instead?
Can it be done without reinitializing the calc?

I used YFNX and PWRX as you mentioned but I still have the same issue.
Last x shows 0.0025 -67 again.

Try this:

Page 4: LIB4
Page 5: TIME
Page 6: Depends
Page 7: Depends
Page 8: AMC OS/X
Page 9: YFNX
Page A+: PWRX

Assuming you want to use AMC-OS/X (you should) they need to be installed in the above 'order' as there is subtle interplay between LIB4, AMC, YFNX, and PWRX. By order, I mean they need to be in increasing page order sequence as shown, the exact pages don't matter. This should resolve your issue.

Thank you.
However, being still a newbie with my CL, I don’t know how to key that in. Still learning....
What is AMC OS/X?

Here's the sequence to load this configuration:

• Load Extra Functions Extreme into Port 1U (Page-9)
XEQ MMUCLR
“YFNX”
XEQ PLUG1U
XEQ MMUEN

• Load Library-4
“804040-8120”
XEQ YPOKE

• Load AMC CCD-OS/X into Page-8
XEQ “PLUG”
“OSX3”
8

• Load PowerCL Utilities into Page-C
XEQ “PLUG”
“PWRX”
C


AMC-OSX is Angel's version of the best portions of the CCD ROM's OS Extensions (with a few extra goodies thrown-in). If you're an active 41 user, you will almost certainly want this installed.

The manual is here: http://www.systemyde.com/pdf/AMMC_OSX_Manual.pdf

Don't worry about learning it all at once, but do keep the manual handy as this module helps in sooo many ways, you'll want to check it out often until it becomes 'normal'. The only trouble with this ROM is I've come to expect it to be available in every 41 I pick up... lol.

I’ll give this a try tomorrow, and report back.

I’ve just tried. It seems too complicated for my actual needs at this point of my learning curve.
Right now I just need what I wrote above. And after loading what you suggested I can’t load 41AD, SM44, etc...
It returns “NON EXISTENT”

Maybe when I’ll be more advanced I’ll use the OS/X

However, I do need the Last x to operate properly...

Thank you for your time and patience.
