Differences between the DM-42 and upcoming DM-41x?

[Namir]

I find it amazing that after 40 years, a new version of HP41C (the 41CX to be more exact) is appearing and is being well received. While it is easier to program in high level languages (and even in HP-71B BASIC to some extent) like Python, Matlab, Excel VBA, and so on, whose codes are all easier to read, I still find the clever tricks of keystroke programming interesting. I was using a few such tricks in programming the Bessel function for the HP41CX, HP-29C and HP25.

Of course, documenting the RPN programs is paramount to make them readable later.

Cheers,
