DM48 Still Wanted
Re: DM48 Still Wanted
Unless there are any lawyers on this forum (I can't imagine the Venn diagram between HP-48 users and lawyers!), maybe what's needed is a Kickstarter to hire a lawyer to investigate the current status of the HP48 ROMs and negotiate open-sourcing them from whoever currently owns them.
Re: DM48 Still Wanted
In order to contact them and for this to be even considered by HP, one would need some credentials. Perhaps SM stand better chance than just a simple fan.
It would indeed be interesting to know for sure about the HP48 series ROMs, or as I mentioned, the HP49 non-CAS code.
Hasn't HP outsourced what was handled by the calculator division though? That would make it less likely for anyone to care answering, but as you say, there's nothing to lose by trying.

Re: DM48 Still Wanted
Has anyone looked into how hard it would be to port Emu48 to DMCP?
I mean, if the community does the software part to make it a 48 anyway, SwissMicros could sell the hardware with some other software. Plus42 might make the most sense. I guess 43 (with operators on the right) is pretty much a good fit as soon as you make the extra row available for the user to define, while the DM32 software might be even easier for SwissMicros to adapt and use.
But my best guess is that SwissMicros intends to make a from-scratch DM48 software out of their DM32 software. Alas, I would be surprised if this can be done in any less than many years.

Re: DM48 Still Wanted
Great layout and functionality, but yes, very poor quality... my HP48 died because the keyboard. The problem was easy to solve, but it was nearly impossible to open and reassemble the case properly (unless you had very specific tools).
About the ROM, some years ago I read (sorry, I can't remember the source, but it was discussed in this forum) that it can be used, but for free, so can't be used to build and sell HP48 clones. That's the reason for so many free emulators. I really don't know the situation nowadays.
Re: DM48 Still Wanted
You mean your HP-49g? I'm confused now.
As for the HP-48, I still own the HP-48SX I used at uni. I suppose I'm generally careful, but I've used it a lot and it never failed.

Re: DM48 Still Wanted
Sorry for the misunderstanding (my fault).... I mean HP48. A lot of HP48G/GX units had keyboard issues because bad contacts due to some case strength loss. In ebay you can find a lot of units with the mark "keyboard issue" or with a rubber band between the screen and the keypad (the quick solution).
Yes, but unless I missed something (like H48 instead of HP49 ) the situation is far to be clear... now the HP48 ROM is some kind of abandonware, with a blurry legal status.Have you read the latest posts?gopper wrote: ↑Sat Sep 24, 2022 7:05 pmAbout the ROM, some years ago I read (sorry, I can't remember the source, but it was discussed in this forum) that it can be used, but for free, so can't be used to build and sell HP48 clones.

Re: DM48 Still Wanted
No, it's no problem, it was just confusing because I wasn't expecting to hear such problems about HP48 devices, so I wasn't sure it was a reply to the HP49 or the HP48gopper wrote: ↑Mon Sep 26, 2022 10:57 amSorry for the misunderstanding (my fault)....

Sad to hear that about the G model, and that yours died because of this. The beginning of the end for HP, maybe.
Re: DM48 Still Wanted
The last thing I read of consequence was HP used copyrighted material from other companies/pepople/things and some of those are not around to "okay" anything.

I still believe let us users load the ROM. Why not make a modular calculator. I can order the parts I want to make the parts I need. I believe not putting an extra row of keys on the 42/32 platform is an oof.
Waiting for SM to release DM42 hardware with one additional row of keys.

Re: DM48 Still Wanted
Agreed. Even if it was just better equipped for running some newRPL equivalent, having the extra row would definitely open options that do not currently exist in terms of offering options to RPL users.
DM42, DM16L, and a menagerie of HPs thanks to CAS (Calc Acq Syndrome)!
