SwissMicros Calculator Forum

Great news, that was faster than I imagined. :) I'm not a user of Ruby and have no need to extract XM files, but I presume you have a very specific application in mind, related to your telescope IIRC, and it would be great if you could share the overall scenario and instructions here (or a link here...

The yellow paint on the [shift] key wears off on some units; it depends on many factors but is common. This issue is common for all BETA units. Look in the prior messages, various users have tried different techniques to mitigate this, however in my own case, I've used a 41 long enough that my finge...

There is a new 'BETA-3' DM41X release available on the SM site here (as Pierre discovered!): http://www.swissmicros.com/dm41x/firmware/ (file DMCP_flash_3.18t03_DM41-1.11t08.bin) This is a brief summary of the DM41X changes in this release: - Added Module ROM Map screen ([shift] [SETUP] [2] [5]) ......

Not sure if you're looking for feedback from me, but if so, here goes. The HEPAX module (in the distribution on the SM site) has been tested extensively by a bunch of folks for many months, and has generally been found to have no problems. There is reluctance to force the 41X module loading sequence...

Nice review!!

Thanks for sharing this here Geir.

One thing was not clear though - did you like the screen?

[CST] and [CONF] will be used for future features.

BETA-3 is coming soon to a Forum near you...

Among the names suggested so far, I like SSHOT best; I think the period isn't necessary. And I agree with Jaco that I frequently hit the wrong shift key first, and then when hitting the second shift, would create SSHOT files for no good reason, so I'd prefer a different key location for this command...

No problem, Bob - once you wrote what you meant I can comprehend your intentions ;) Please allow me quoting footnote 27 from the very same page where Σ+ and Σ- are explained in the ReM (and directly referenced from Σ+ and Σ-): Σ+ and Σ− return temporary information as shown in Section 2 of the OM a...

This is a nice reminder of how we can use functions effectively even if not using them for the task intended, thanks Nigel. The RefMan does state some of this for Σ+, but not for Σ-, and as Walter points out below, the OwnMan does explain it as well. @Walter - I'd recommend these small enhancements...

The other main use for sigma-plus and minus is for adding and subtracting lists of real numbers using sum-x, or complex numbers / 2D vectors, using sum-x and sum-y. On modern calculators there are other ways to do this, but I expect that quite a few people are in the habit of working this way. I'm ...
