An online catalog of modules based on the 41CL collection can be found here

You can get the module roms themselves from Monte's site

Look here on the 41CL site:
http://systemyde.com/hp41/manuals.html
Look in the 41CL Calculator Manual. Pages 49-59 list all the ROMs in the 41CL. I've always taken that list as the definitive list. I've not counted them, though.

That's OK, I've done that before too when a previous post didn't show up on my system until after I'd answered. You wouldn't happen to know where the instructions for those ROMs are, would you? I'm particularly intrigued by the one titled BASIC. I'm always on the lookout for BASIC interpreters/compilers for various systems. I don't know if that BASIC ROM is actually a version of BASIC, though, without the manual or QRG for it.

Here's another database of HP-41 modules online:

Sorry, but no. I guess your best bet may be to contact Monte, or Angel, or Sylvain.

Most of the 3rd-party ROMs do not have any documentation; the vast majority come from users that have found or purchased 41's with modules inside, and either donated them to folks that know how (or got procedures on how to do it themselves) and they extracted the ROM images.
Monte has been collecting them to add to the 41CL Flash library and has become somewhat of a clearing house of the latest versions. Note that the 41CL uses modules in the *.rom format, while the 41X uses modules in the *.mod file format. For simple, 4K, 1-bank modules, a .rom file can be easily converted to a .mod file, but for complex, multi-page modules you need to use more sophisticated tools like the excellent MLDL2K tools.
But if you need some of those, ask here first as there's a good chance someone has already built that first.
All that said, TOS and here in these forums are the best places to look for documentation for these 3rd-party modules, but if you still can't find it after looking, I'd suggest creating a new thread specific to that module here in the "Not Quite..."
Also, look at Matthias' amazing 41 ROM Module database: Not all of these are available from public resources, but if you find one you really want to check out, you could post a request here as well:

If it is old, then we are, too... :(
Sorry, duplicate info. I, too, missed the page break.
RE: DM41X - Gene - 01-30-2020 11:18 PM
I thought the BASIC rom was the BASIC interpreter from the PPC JOURNAL V11N2P11.

I can hear the journal pages flipping from here...
RE: DM41X - Ángel Martin - 01-31-2020 08:57 AM
My notes on the BASIC ROM are sketchy but here's the main content:
"BAS" by Erik Christensen PPCCJ V11N2p10
"BASIC" by Per Liedberg UPLE #11286 (available at TOS, see the UPLE section)
"AFI+" by Erik Christensen PPCCJ V10N5 p10
"FORMULA" by Stefan Fegert HP-41 in der Praxis
"AOS" by Greg McClure GMC ROM
"FIFTH" by D. Cody Kyrobie PPCCJ V11N2p5 - March 1984
Hope this helps,
ÁM

The URL below points to a ZIP file with the most recent versions of my modules - plus a few extras:
http://www.swissmicros.com/dm41x/fat/
Generally speaking the MOD files on that zip archive are identical to those found on TOS and other sources (pls. mind the revisions and release dates). I don't remember having to modify them for the DM41X, so they should all be 100% compatible (famous last words...) . Do report incidences if you run into some.
Remarks:
Most of the advanced modules use the LIBRARY #4 ROM. Make sure you always load that one/.
Some have different versions depending on the page# to plug it in.
- If you don't use the printer page#6 is available for the AMC_OS/X and HEPAX_4F to use.
- page #7 is also available (no HP-IL folks), so those two above and the WARP_Core can be safely plugged in it as well.
Enjoy,
ÁM

But you *can* play pinball - that is if you consider the classic game in the GAMES ROM to be a decent surrogate ;-)

I don't know enough about the machine so i can be way off but I believe that to pull that off you'd need direct access to the DMCP code. The 41 emulator doesn't know a thing about the LCD used, I'm afraid...
Sure I'd fancy a modern version of PRPLOT on the screen...

Mine has been ordered tuesday evening and has arrived this friday morning. My department in France is close to Switzerland so this explains that.

Nice shot!!
The lighting is just right to make the ZenROM overlay look like it's glowing.
Is the BlankNut also a HalfNut?
What about:
A Tall-Keys machine
A DM41L
A 41Y
A 41W
A CL (can't tell, is the upper left machine a CL, label is hard to see)
We could ask Sylvain to show us his 41 family photos, but I understand the MoHPC web-host has requested us to not use bandwidth excessively...

Given how much they have to be nursed to mantain their OS alive, I don't think they are a viable collectable as of today.

This is only an excerpt, but I know that Sylvain's collection will easily dwarf mine, however this was only meant to show how it all evolved in the last 41 years.
RE: DM41X - rprosperi - 02-01-2020 11:40 PM
Interesting! The TK CV must be a frankencalc, right? I'm pretty sure production switched from TK to normal before CV production began, right?
Actually I find the DM41L to be much more interesting than I expected. It's soo different from a normal 41, it's like exploring an entirely new machine. It is very interesting. It is not a 41.
I agree the V and W are intriguing, but cost FAR more than I would ever pay. But rare is like that...
Yes, July is coming and I hope the 41X will introduce the 41C to a bunch of new users on its 41st birthday.

RE: DM41X - Paul Dale - 02-02-2020 08:32 AM
I'd recommend reading "Calendrical Calculations" by E. M. Reingold & N. Dershowitz. It contains some amazing details but not a lot relevant to modern date/time computations.
