Anyone wanting a new platform for super high speeds is probably better off with a DM42n, and having more memory does not improve a 41X as it already has more RAM than any 41 could ever use. Just wanted you to know, so you aren't waiting for something that isn't likely coming...

Thanks Bob! I appreciate your thoughtful explanation!
Just to play Devil’s advocate, is there a counter argument that even if an enhanced hardware DM41X would not be of much greater value to the consumer, it might still be likely because it would benefit the manufacturer to consolidate production on one hardware platform for their top 3 flagship models?

The reason SM came out with the DM42n is that the CPU in the DM42 is obsolete and almost impossible to get now. Their hand was forced. When the hardware the PX41CX based on is old enough, they'll have to either upgrade or go out of business.

The same goes for everything, when the supply runs out you need to come up with a replacement. But there is a stockpile and a demand to consider. I suspect the "old flagship" assembled PCB stockpile, or possibly the CPU stockpile, at SM can serve the DM41x demand for a long long time - but would have ran out much more quickly had the DM42 stayed on that platform for longer.

As for the AVR128DA28 in the PX41CX, it is in production and to my eyes it does not seem to have a high risk of being outdated and out of production anytime soon - but the latter part of that statement is rather dangerous speculation, really. If you need your business to continuously have something to sell, keep a stockpile big enough that you have time to redesign if you at any moment find yourself suddenly unable to get anymore. Then again, most of the time warning signs can be early or extra stock can be found from some distributor or other.

Sure, hardware consolidation is a helpful thing from that standpoint. I just don't expect it to have any impact in this case. For what is relatively small runs of PCBs with relative mass availability of the components anyway, the impact is most likely very small. Not to mention the old and the new SM flagship are quite close to the same thing except for the SoC, so very very small. And finally, my above comments about stock and demand.

But if I were to expect a new calculator from agarza, I'd expect one with the same hardware as the PX41CX except for faceplate labelling and firmware. Because it's easy. Or... something entirely different, because it's a challenge, and these are relatively small quantities of generally available parts with very little in-house hardware work anyway.

How painful is it in adjusting to the keys?
I love the idea; but those keys

They might look strange but they are otherwise just fine.

I'm working on designing a new font for the PX-41CX.
Trying to recreate the 14-segment style of the original HP-41C.

Any ideas or suggestions?

Is True-Type and option — if only as a starting point to create an pixel font? I have this one which I use for my HP45 Emulator.

I used a different one before but that was not as nice.

Thank's, that will help me create the lower case characters.

Hello Alex,

I have the starburst segments in .ai, .psd, and .svg formats which should aid you in the creation of bitmap fonts.

I extracted the outlines from the same font posted by @krischik.

The file is just a bit too large to add as an attachment to this post.

Glad to be of aid. Have you seen my dump decoder tool I announced in this post?

Yes, I plan to test it this weekend.

I still need to learn Ada and figure out how to run it on a Mac.

I downloaded it just fine. Was it a single download and I snatched it aways? Anyway, here are more resilient download link:

I provided binaries for Window, (x86) macOS and (SuSE) Linux. But if that doesn't work for you with the new Ada package manager compiling from source has become very easy. The package manager will download the compiler and all needed libraries and then build the executable for you.

Alex - Do you know Luiz Viera's 41 font, available here:

http://www.hpmuseum.org/guest/claudio/41chrset.ttf

This is well known and has the source for many (most?) projects that have used 41-ish fonts.

For some reason that font is not working on my Mac. It does not pass the validation check.

I've just emailed you a couple files with possibly alternate (fixed?) versions of this same font, which open on my Windows machine without issues.

It seems that MacOS is very picky on the way TTFonts are built.
Does anyone have experience using FontForge to try to fix the HP41 TTF?

[Sylvain Cote]

The no longer developed FontVal application for macOS & Linux validate TrueType Fonts internal structure then produce a report. Here is the FontVal Report for the 41chrset.ttf font.

Alex,

See attached ZIP archive. It contains both 41charset.ttf and 41charset_x.ttf created in OpenType TTF format using FontLab on macOS.

These work fine on my iMac Pro...
