Re: [DM15L M1B V25] Can't jump past line 448

Thanks for the hint, I updated to DM15 M1B V28 and still get the same error (Can't jump to line numbers above 448, neither with GTO nor with GSB) I suspected not, but at least now it's clear. I'm sure it is indeed a limitation of the ROM code that only envisioned a certain amount of RAM. Though SM ...

Re: [DM15L M1B V25] Can't jump past line 448

Suggest you update the f/w in your DM15. It appears you are running V25, but there have been 3 releases since then, including at least one fix which corrected (a possibly unrelated) bug pertaining to extended memory access for the DM15_M80 and DM15_M1B configurations. I'm not saying this will fix th...

Re: How did you discover SwissMicros?

I wonder how many discovered SwissMicros by mistake on their search for an accurate timepiece, and accidentally bought a DM42 thinking it was such a timepiece, then proceeded to moan about the accuracy of their calculator in keeping time. I wonder. :lol: 1 +. Should you come to NY keithdalby, I'll ...

Re: DM42- clock losing time

All the original 41 versions (CX or module) included a crystal, were reasonably accurate ... What does this mean in numbers? Every machine was different (I guess due to the other components in the 41 as well as mfg. variations) but as I recall, for my 41CX drift was about 1 minute in a month or so,...

Re: DM42- clock losing time

Any practical reason why accurate time is important on this calculator? IMHO, it does not need to know the time or date. Calculations on time or date values, yes, but I'll happily look elsewhere for accurate measurements. Am I missing something? Except that the original HP42S has it? BTW, how accur...

Re: Thermal Paper?

I started an experiment on 13th March 2018 (I think it was; I can double check on Monday). I printed something, then fastened it to my whiteboard at work where it is exposed to daylight and artificial lights all day long. I wanted to see for how long it was readable. It's still perfectly readable. ...

Re: Thermal Paper?

For original HP paper, on eBay, search using "HP calculator thermal paper" and you'll find listings for anywhere from single rolls to several boxes (6 rolls per box). From experience, as long as the rolls did not get wet over the years, they generally still work fine. HP sold both blue and black pri...

Re: DM42- clock losing time

It's really a shame we can't get a reply from the developers on this issue It's not clear that there is an issue, just some vague comments that you think it lost some amount of time over some other amount of time; you noted yourself that you didn't even record it. I suggest you do this, to help cha...
