DM42 vs hp49gp (performance-wise)

[John Keith]

In terms of graphics, the Prime is the winner here, with a color display that is higher resolution than the 49gp. The DM42 has a monochrome display but also higher resolution. The Prime G2 is the fastest, but even the G1 is substantially faster than the 49gp or the DM42.

The Python interpreter on the Prime is a nice MicroPython implementation with connections to the CAS for numerical calculation. It is also faster than PPL in most cases. Both languages on the prime are very different from RPL or RPN so it will require some effort to port programs you may have to the Prime.

Another option if you have an Android phone is EMU48, a free open-source emulator of the HP48/49/50 series. It is available from the Google Play store. It is many times faster than the 49gp etc. I believe there are similar apps for the iPhone but I am not familiar with them.
