Re: 43S Alternative key layout --> WP43C

Guys, I wasn't saying that there shouldn't be a corrective action, I was just suggesting that E- might have flaws and there might be better alternatives. I did mention undo, and others mentioned or hinted list / matrix editing. Who needs to be able to remove values which have not been entered in the...

Re: 43S Alternative key layout --> WP43C

Σ-, I think, is not just used as undo. In the history of statistics there are always people who want to prove their prejudice. So if the expected result doesn't fit yet, you can remove the data point you suspect to spoil the nice result with Σ-. +1 Any fool can manufacture a preordained result ... ...

Re: 43S Alternative key layout --> WP43C

As a general rule (AFAICT), calculators that store the data points don't have 𝚺+ and 𝚺- buttons; they have list editing functions. The calculators that have 𝚺+ and 𝚺- buttons don't store the data points; they only store summation data. I guess if 𝚺- is used to delete previously entered data points ...

Re: 43S Alternative key layout --> WP43C

When entering the "STAT" menu the ∑+ is on the unshifted plane while ∑- is on the (f)shifted plane. As the ∑+ is already directly available on the keyboard I think the ∑- should be on the unshifted plane for convenience and the ∑+ could go to the (f)shifted plane. Günter I agree and I have requeste...

Re: 43S Alternative key layout --> WP43C

At the hhc 2019 there was some spare time available, therefor I thought it's a good opportunity to talk about the WP43C. A quarter hour before my talk, I quickly hacked some words together. So please bear with me when it seems to be confusing and stumbling at times. https://www.youtube.com/watch?v=...

Re: 43S Alternative key layout --> WP43C

DM42 issues ... still persist. I've been holding back on purchasing at least 2 DM42s (one for me, and one for my enthusiastic, tech minded 16 year old) until I was confident that those pesky keyboard issues had finally been resolved. So, you can imagine how deflated I felt when I read the following...

Re: buttons that don't register well

Has anyone tried replacing the dome switches? I purchased a DM42 and received it last weekend. I immediately loved everything about it except the keys. Keys were hard to press, and many of them could click without registering unless i pressed harder after the click. I decided I was intent on keepin...

Re: 43S Alternative key layout --> WP43C

-First Q: Does the idea of a fixed HOME menu (in addition to the g[7] key and 3 x shift) appeal? Will it be better? Is there an improvement to this idea? A1: Honestly, it didn't immediately sound appealing, but it might grow on me. :-) I would like to see some examples, and learn a bit more about t...

Re: 43S Alternative key layout --> WP43C

And since those archaic letters are not used for more than 1000 years, I don't see a pressing need for them - we also won't include Germanic runes etc. It may be ignorance on my part, but I am not aware of archaic Germanic contributions to math and science rivalling the Greek? You are right. I shou...
