Has anyone tried synthetic programming with the DM 41(L)? I have zero experience with synthetic programming and curious.

Hi Eddie,

Err... No it isn't... It's a standard USB to miniUSB cable. There's no DB9 connector on it Smile

Hm, is the DB9 even part of the standard? Or for that matter, the big brother (DB25)?

The DB25 is part of the official standard (de jure) but DB9 is not although it has been standardized in a generally accepted way (de facto).

I am considering removing my review for the DM41L from my blog. Any advice would be appreciated and thanks in advance.

I'd treat the DM42 debacle as an aberration rather than the rule. SwissMicros calculators are still of high quality and I don't believe you should penalize the DM41L for it. An objective reviewer reviews the product in a vacuum regardless of the actions of the manufacturer. Does the product do what it's supposed to? Is it well made? How does it compare to other similar products?

Please don't get all PC on us and refuse to treat the products objectively just because you don't like the manufacturers. No products from Microsoft, Apple, and many others would be reviewed if reviewers judged the companies rather than the products. That's my 2 cents anyway.

I agree with Tom. What you wrote was true then, and it's true now.

Further, SM's track record has been excellent for years, and we hope this latest issue will be resolved favorably. If it's not, you could always do so later, if justified, but hopefully it will not come to that.

Not supporting them with another purchase until they satisfy your standards of conduct may make sense (this is very much a personal opinion), but removing prior positive comments about SM and their products seems unjustified, at least to me.

I agree with Bob - and consequently with Tom. While I understand the nature of the complaints being made, it's also a tad surprising the zeal shown by multiple parties by the strict allegiance to the so-called open code - as if they had a vested interest and were being taken advantage of.

I've been sharing my MCODE and other programs for over two decades so I get it. Yet this reaction feels strange. I haven't seen or read any statements by Thomas O. that others have referred to (?) so as long as that's not a problem with him I don't have any issues either.

Eddie W. Shore · 03-30-2018, 01:07 PM

Good. I really don't want to take down the review for a very solid product. Thank you Tom, Bob, and Angel.

Sorry Ángel,
I think you misunderstand what the GPL is about. It is not just a matter between the originator of the software (Thomas) and the violator(SM). It is a matter between SM and their customers (us) because they denied us our right to have access to the full source code. This prevents interested parties from building their own versions of Free42 to run on the DM42. The zeal you mention is in place to protect our own rights.

Having said that, it seems as if SM is going to change their attitude on this issue. If that's the case the zeal would be justified.

GPL is a licence based on an ideology. It is the belief that everyone has the right to have the source code to all the programs they are using.

Some people think it is about free software, as in no cost, which is wrong.

Some think it is about stopping others from making money from their work, that is also wrong.

People should think a bit before they put a GPL license on their work. What am I afraid of, what do I want to accomplish with it?

Thomas clearly understands GPL and its intention, that is why he uses it. SM denies a lot of people their rights under GPL, most likely without really understanding it. Being in the software business, I take serious on these matters.

Having said that, I stopped using GPL myself years ago as I do not believe in it, and I think it is causing more harm than good. I release my open source project with a BSD license and what SM does is legal with such license. For my own open source projects, I am fine with that.

I also believe SM has a lot to gain from openness with their platform, but that is an unrelated (but also important) matter.

Hi,

For what it is worth, HPCC's Datafile Vol. 35 No. 3 p14 has an article by Geoff Quickfall titled "Synthetics and the DM41L: Load Bytes". He includes the hex dump for the LB program.

Hi!

This thread is a little dated but it is perfect to accommodate the few comments that I would have inserted if I had been more attentive.
I too have been enjoying my DM41L for just over a week now!
Here is what I wanted to share in this forum a few days ago:

--------------------------------------

I ordered a DM41L from the SwissMicros team.
I received it about two weeks after my order was processed.

It truly is a very beautiful object!

The shipment was made in a sturdy cardboard box, in calculator format.
The packaging was neat, a little precious with a crossed kraft paper covering, as I have already seen for a book that the bookseller
- its sender - wanted to protect it during its postal transit.
The feeling of weight, without excess, appeals. And a good impression of solidity emerges.

I quickly entered a first program, one of my usual ones, to check how my new “little one” behaved.
The ON button is barely flush and, as a 'Voyagers' regular, we notice it straight away!
The screen is very readable and clear.
Entering the first program may still be a little confusing: the keyboard seems to be "proof".
Key springs that are barely less flexible than we would like, perhaps?!
In any case, we tell ourselves that the electronics will fail before the keyboard shows signs of weakness. It's a keyboard that suits him well.

What is remarkable is that I enter my program lines quite naturally even if, ultimately, I have a machine that I do not yet know.
At first, I am a little confused when I systematically look for the letters K, L, M or N in the second line of the right part, in line with the second line of the left part of the keyboard which corresponds to the sequence F, G up to I and J.
But you have to look at the first line of the right part of the keyboard as you do if you were reading a book by going from the end of the left page to restart by the beginning of the right page! I'll get the hang of it quickly.
Something else to mention that seems trivial but is actually very pleasant on the DM41L, when entering program lines, is its speed of handing over when finishing the entry of a CAT 3 function with a XEQ by typing all the letters on the keyboard. I often found myself having to redo a keystroke (STO, RCL, etc...) behind a MOD or a PSE because the 41CX was not ready! Here, the 41L is ready again immediately after exiting ALPHA mode!

When executing the program, at first glance, the little duck is a little surprising: it has well-extended wings and proportionally larger than its body.
Good ! It will not be sensitive to drafts!

The speed of execution is pleasant. I had seen criticism for respecting PSE breaks and display times. I have nothing to complain about.

Accustomed to 'Voyagers', as I mentioned, there is however a specificity of the organization of the keyboard which oppresses me a little.
I'll have a harder time getting rid of it! This is the arrangement of numbers and operators that are reversed.
I ended up with a value 4 instead of 5 in a biorhythms calculation program:
accustomed to my HP15C doing so, I naturally looked for the 5 where my fingers remembered where it was, of course.
And for the operators, I look twice too.
I don't remember so much hesitation when returning to my 41CX, even after a long period of use of my 11, 12, 15 or 16 which have a common layout of the keys!
Surely I need to “learn” (practice) it a bit, my 41L!!

I must also tell you, after several hundred program lines entered, and multiple XEQs without ASN, I also wondered about the durability of my index finger.
But it's already forgotten, I no longer pay attention to it!

On one of my programs, I also had to make some adaptations to the use of the GETKEY function.
The codes for the 'O' and 'N' keys (understand 'Y' and 'N') were no longer the same.
It was done quickly.

Then, I wanted to try to enter the Byte Grabber dedicated to synthetic programming.
I launched Memory Lost without difficulty (I thought I had read the opposite about it) by following my usual procedure on my 41CX.
The rest of the process also went smoothly and everything looked as usual.

In the end, I'm really happy with my purchase: I put my 41CX away and took out its batteries. I feel good with the 41L and it is really very practical to transport: it does not take up space.

Some of you may be wondering why I didn't directly choose a DM41X rather than a simple DM41L.
In fact, there was no real debate for me.
The format to which I am very attached is that of 'Voyagers'.
The memory of the 41L is sufficient for my use. And my 'Advantage' module is not essential to me on a daily basis.
My choice naturally fell on the DM41L.
(I'll see if I end up getting used to its numeric keypad and the location of its operators! There will always be time to look at the 41X if I miss the SOLVE and other INTEGRATEs too much.
And then, I wouldn't want disinherit my HP15C or my 35S too quickly!!)

In all sincerity, if the HP41CX already suits you as it is, you will not be disappointed by the DM41L: it will live up to your expectations.
It will certainly be a discreet tool, truly functional on a daily basis and practically unrivaled in its format.

In the meantime, I still have a lot to try on this beautiful calculator which is a real success!

--------------------------------------

I can still add today that I really appreciate its extended X-Memory which is increased to 360 registers (124 + 238) when my 41CX only has the memory of the basic X-Function module (124).
I have stored all my usual programs there and this allows me to free up all the internal memory of the calculator to test a large program, if necessary.
It’s really very practical!

Keep yourself healthy

Laurent
