Re: Flashing DM-41 firmware on DM-15

May be there is a "business case" for SM to sell a blank DMxx (credit card format) xith all the DM10, DM11, DM15, DM16 and DM41overlay layout?

... Nowadays, however, a DM41P featuring I/O like DM42 plus benefitting from the big display plus some way of loading ROM images would make more sense than a crippled DM42L. YMMV.
+1000 (I/O= being able to read write I/O thru programming and not only loading files)

Re: Firmware V25 for DM1x/DM41(L) units

I am not in the religious debate of portrait vs landscape. That's users personal preference and SM sales opportunities... Just saying that (to my eyes) running a simple NUT emulator on the DM42 hardware to simulate an HP41CX and adding stack display isn't worth it. Whereas rewriting the HP-41CX for ...

Re: DM41L versus DM15?

You can do a "HP41 vs HP15" web search. The subject has been hammered!

For me DM15L is a ONE (1) program calculator vs DM41L a MULTIPLE programs calculator (multiple program spaces, global labeling, etc...). The rest is "details" :D

Re: Firmware V25 for DM1x/DM41(L) units

The DM41L is sweet and has it's aficionados (myself included). A DM42L would definitely find buyers (myself) even with only two (2) lines display. The DM41P is useless to my eyes if it only runs the original ROM in emulation. That would greatly limit it's capability. Only a re-written DM41P makes se...

Re: Firmware V25 for DM1x/DM41(L) units

@grsbanks I still have an un-answered question for you or SM. DM15L is an LPC1115 emulator for NUT CPU running HP-15c ROM. DM41L is also an LPC1115 emulator for NUT CPU running HP-41CX ROM. So here is my question? Why would the HP-41CX be way faster than the HP-15c (8 Queens benchmark) and their ROM...

Isn't the DM41L an HP mutant with exceptional powers?

Re: Firmware V25 for DM1x/DM41(L) units

Hi, this release is really great and upgrading went smoothly on my DM15L and DM41L. The X-Mem module is really a surprise! But... as you might expect it brings some new questions : why did you only add one (1) X-Mem module? - max available memory, or - you are keeping space for future ROM loading ab...
