The magic number for me is "1".

This is my magic number as well. FWIW, my board is V3, Copyright Date 2017.

Hp41 was the best, do not change anything.
Maybe that's the answer. If someone could shove the 41 CX rom into the DM42, then we could be reassigning keys and manually typing in functions like it was 1979.

Re: PUSH/POP stack

As I understand it, one disadvantage of this method is that the stack can't contain a matrix. The other way (using registers) would be able to support a matrix on the stack.

Re: Case for Voyager 'L' size

... a copy of Avogardro's Numbers (a small reference book), ... Is that something that's obtainable for the mere mortals on this forum? :) 20190329_094838.jpg It looks like it's out of print. It was compiled by Herbst and Schiller, copyright 1988. Mine is an artifact from my University days. It's a...

Re: Case for Voyager 'L' size

For my DM42, I use a hard case for the HP-35S. It holds the unit securely, and has enough room for a HP-42S quick reference, a copy of Avagardro's Numbers (a small reference book), and a few business cards.

Thoughts on DM42 User Manual

One thing that bugs me (not really, but it is something that I've noticed) is that the DM42 User Manual is written for someone who is familiar with the HP-42S or Free42, and needs to know how to do DM42-specific things, like update firmware, change system setttings, save files and state-files, etc. ...

Re: Spreadsheet App for DM42

If you're working within a single equation, the Solver is an awesome tool. You can manipulate many variables and do what-if tests quickly. In the 90s I was running a rad lab in the field and this saved me sooooo many hours.

Re: buttons that don't register well

I had the DM 41 (same hardware as the 15) before the 42 was available, and didn't notice any problems with the keyboard. The keyboard on the 42 is generally fine; problems seem to be the exception, rather than the rule. I wouldn't worry too much about it, it really is a beautiful product.

Re: UPDATE: DMCP-3.11 / DM42-3.11

Update: applied "the solution" from Michael. Using the calculator at random moments for a brief period. Battery is being used as such and we'll see where it ends the coming month. It's a vast improvement over the previous situation although I'm a little skeptical still. Let's see in a month from no...

Firmware Update - High current usage

Has there been any progress on a firmware update for those of us who've been hit with high current usage on the latest firmware? I got an email from David last week that DM was working on a software fix, but haven't heard since.
