Hp50Emu48 g vs Swiss Micro DM42

[Gil]

I see so much discussion about
Swiss Micro Dm42 that it awoke my interest.

3 questions

Does the Swiss Micro Dm42 have all the
features of the HP50G?

Does it calculate faster than the HP50G EMU48 (the latter about 100 x faster than the normal HP50G)?

Besides the number of digits, what are the pros of the Swiss Micro Dm42 in comparison to HP50G (EMU48)?

Thanks for your insight.

No. It has all the features of the HP-42S, plus some additional. It's an RPN calculator, not RPL. It's not even very similar to the HP 50G, except in the general sense that both use (mostly) Reverse Polish notation.

AFAIK, the only other calculator that's similar to the HP 48/49/50G series are their predecessors, the HP-28C and HP-28S.

No, because the DM42 is based on the HP 42S.

No, your smartphone or computer might be faster. But it is faster than the original HP 42S.

The DM42 is a physical device with keys. Emu48 is a software emulator (that can be used on touch devices).

Hi, here's my view
The DM42 is for real and complex numerical calculations. Some limited matrix functions. But it has a very nice screen, and is very fast compared to the original hp42s. If you still need more speed, run the same programs on a free42 on a phone. And there is the physical size which is very neat.
On the other hand, if you write programs in C for the HP50G in hpgcc3 and load it on the physical HP50g you get a speedup of about 100x as it is no emulator, and it utilises the arm cpu (overclock it to 120MHz). Which is also about 20-30x faster than any asm written on the calculator. For any "challenges" I simply consider this cheating. This is good for pure numerical stuff. No access to the CAS. The number of people actively doing this are next to zero, so there are no fun discussions. And you need to install a non standard rom.The HP50gEmu48
is probably somewhat faster, but not by much, as it is far less efficient.
