Re: DM41X V2.1

rollover should not be critical at this stage. Six years ago, I was in an accident with a "wrong way" drunk driver. My left hand was crushed in the accident (I am left-handed). I recovered 95% of the functionality in that hand. However, I have one finger the refuses to perfectly synchroni...

Re: DM41X V2.1

Exactly emulating behavior which isn't particularly useful ... I'd wager you could find plenty of disagreement on this point, particularly from fast typers. Hand raised! Both hands raised--if you get my drift... ;-) So you're saying that accurate digit entry isn't important? SM goes to the effort a...

Re: DM41X V2.1

DM41X Fixes and improvements: When you use the calculator to reformat the FAT disk, it now creates all the various sub-directories. Updated without issue. This works correctly if you use the "Format FAT Disk" option. If you format as part of the "FAT Disk Media Test", then not a...

Re: Two-key rollover causing duplicate keystrokes

I might add that even the lowly HP EasyCalc 100 4-banger supports two-key rollover.

Re: Two-key rollover causing duplicate keystrokes

I reported this bug during the DM41X beta. I believe it was the very first bug reported (30-Jan-2020):

Keyboard Rollover Bug

As I pointed out in that bug report, it does matter because the DM41X behavior is different from the HP-41CX.

Re: Old HPMuseum HP-30b primality test on the 41x

The 43S is using a completely different algorithm for its primality test. It's using Miller-Rabin . It is set up so that gives precise results up to a reasonably large number (3317044064679887385961981), beyond that it is only reporting probable primes. Pauli Does "probable" only include ...

Re: 43S News

This looks excellent, I am looking forward to availability. I collect stands and I thought the age of creating nice calculator stands had passed us by... Do the slots on each end hold the machine up at different angles? Which common machines, other than the DM42/41X/43S, does it hold? This looks to...

I can confirm EM41's reported erratic timing of VIEW using: Fill stack with 1's 01 LBL TEST 02 VIEW ST X 03 + 04 GTO TEST The display will have a normal delay interval and then show two numbers in quick succession or even skip a number entirely. At other times, the display will not change for 3-4 se...

Re: Source for additional MOD files

Another quarrel about which license should be preferred, and what it asks to abide to, is just what I was waiting for... Your statement here oozes sarcasm and expresses my sentiments exactly. As for the use of the term "quarrel", I would prefer to replace it with "bloody and extended...
