Re: DM42 program with EVERY instruction?

There are no coincidences... After recently finding a copy in my files (no idea at all where I got it, or when) I sent it to Jake so everyone can get a copy, and then seeing Thomas' notes about updating the program to test the import, I thought it may be helpful. Now to try to convince my wife that ...

Re: Case for Voyager 'L' size

The original HP Pioneer Leather Cases work great (they include a flap over the top that tucks into a retaining strap) holding a DM42 and a QRG just about perfectly. They came in Black, Brown and Reddish-Brown (also called Red, Maroon, Oxblood, etc. in various places). They come up frequently on eBay...

Re: UPDATE: DMCP-3.13 / DM42-3.13

DM42-3.13 Update smooth and quick, no issues encountered (I used combo file). Presumably creating (and removing/renaming) directories in the PROGRAMS folder can/should only be done via USB-connected PC? Is there a sense of the 'current' folder being retained, and if so, what happens if that folder i...

Re: Moon Landing on DM42?

Here is a version for the 41C family, which should be easily ported to the 42S, it may even run as-is, I did not examine it closely:

Re: Running an HP 50g program on the DM42

Oh, and as for posting the code that isn't possible as it looks as if the program is compiled and there isn't any source code provided as far as I can tell. I looked at the 50g program and it will not be easily ported to the 42S; it is sophisticated and not straightforward, and was written in very ...

Re: Running an HP 50g program on the DM42

Pretty much impossible. The languages used are totally different and there is no way to directly convert it. Of course if you happen to know both languages you could port the underlying algorithm, but that's unlikely. If the 50g program is not too long, if you posted it here, or on the MoHPC forums ...

What (in simple terms) is the reason that the accuracy is improved over the 42S?
The DM42 (built using Free42) use 34 internal digits, while the 42S uses 15 internal digits (12 visible).

Re: DM15L keyboard faceplate is separating

I also sympathise with mezoganet's frustration especially given the price of those units and the several reports that seem to indicate that this is a known defect of some/most DMxL production batches / possibly a design issue that has been going on for several years. As noted, of the hundreds (like...

Re: Firmware V28 for DM1x/DM41(L) units

Thanks SM team! Smooth and fast update, as usual.

And remember kids, seeing "PR ERROR" after updating Voyager models is normal, so don't panic. I did once, and am trying to save you from that embarrassment...

Re: DM15L keyboard faceplate is separating

My DM41L has been ordered on Jan 30th 2019. Out from the box, the bezel did not stick. After mailing Michael with pictures, the solution was to remove the foam under the keyboard. Nothing better, so Michael sent me another bezel. Same problem : bezel does not want to stick. This device has been use...
