Re: 43S Alternative key layout --> WP43C

I successfully compile/run the C43 simulator on linux. Now I'm trying to build my own firmware, using the scripts in DMCP_build, which I'm working my way through. My question is how do I build the pgm files for L1 vs L42 keyboard layout, and does the default scripts produce the L1 or L42 layout? Th...

Re: 43S Alternative key layout --> WP43C

As you all may have noticed, there is a fundamental UI difference between 43S and C43 which hasn’t been discussed here. That is the single [ .ms ] button versus the two buttons [ d.ms ] and [ h.ms ] on the 43S. I should be able to post a release this weekend together with a document detailing the d...

Re: 43S Alternative key layout --> WP43C

Re: 43S Alternative key layout --> WP43C

For differentiation, there are numeric methods for estimating the slope at the end points. For example here . There are higher order methods which are often more accurate and since you're plotting the values, the function will have been evaluated at several equally spaced points already -- i.e. the...

Re: DM42 Fasteners

I sent an email and SM is sending replacement screws. It would be easier if I was simply provided the screw size as requested and I could get the screws at a local hardware store. However, I appreciate the customer service and look forward to using my DM42 without being extra careful. :) Maybe once...

Re: 43S Alternative key layout --> WP43C

... produce a table of the roots found in a matrix on the stack X-Register. I read today that some HPs do such table. The HP71, if I'm not mistaken. I searched and found the reference to be the HP71 Math Pac. Specifically, the PROOT keyword is for polynomial roots, and stores all these roots in a m...

Re: 43S News

Switching fonts for plaintext with all your foreign language support was not trivial. The small font contains many characters not available in the large font, which would require either font creation (for no good reason)... What you call "foreign language" may well be the native language ...
