Is there something to be said for having the “real” keyboard of the DM41. Is the 4 line screenbig advantage? Is loading Roms onto the Dm41 much easier than using a Nov64d ?


I would welcome some views of those who are in the know.


I also have some questions about using the Nov64d.

1. It appears that with Hepax preloaded , you have room for 8 other roms ? Do I or can I keep the XFunction and Time modules in place with the Nov64 installed ?
2. I have an old Mac Book pro on which I can run XP on Virtual Box, so I assume I could load Roms via these route ? I do not have any window based PCs.
3. With the Hepax , I can save my programs via that route or use my card reader.
4. My card reader seems to chew my battery life ! Does the Nov64 suffer from the same problem?

Anyway, all comments & views welcomed.

You have a CV, TIME, XFUNCTIONS, CR, get the Diego module. That is my quick summary. No HP-IL with the 41X.

Multi line 41X display is a welcome feature and more on it below.

Very easy to load/switch ROMs on the 41X.

1-Yes on the HP41 and the 64d module, use with care (XROM module numbers can conflict, and be wary of conflicts in ROM program names being the same). HEPAX has many XFUNCTIONs functions, see clonix41.org for the HEPAX manuals.

2-Not tested VB and 64d flashing. Given the Mac is old, best COA is a W10/11 laptop with a intel 8000 series CPU or newer (my they are cheap).**

3-Saving programs to PC is not straight forward, have not ran through the steps. It is documented on this site and on clonix41.org. Yes, you can use your CR to save programs with the 64d module attached.

4-No

There are things I really do not like about the 41X. Keyboard labels, inaccurate battery level (one bar down and I get intermittent MEMORY LOST). One size fits all display (width) and character zoom problems in PRGM. Pluses are 41X to PC interface, speed, multi line display, is a CX plus XMEMORY and the batteries are cheap. The 41X is a good tribute calculator, not a great one.

See this and this, for additional good experiences with the HP41 ecosystem.

**Please do not use XP. Windows 10 runs unactivated. Meaning no dollars spent on the a license and you avoid the security pitfalls of an unsupported OS. I have ran 10 and 11 unactivated (no dollars spent on a license), for years. Which is great of MS and is great for spinning up and testing VMs.
