He did provide a link in his post but it wasn't super obvious:

You're right that it's a Limited Edition, and the video confirms your point that it is quite a lot slower than the DM42 for the example shown.

Thanks for pointing that out, Bob, the links were indeed well-integrated into the text. Also, I was surprised to see these videos, I thought I had seen about all of this type; always good to see more.

Indeed the primary goal of the 41X was to easily and flexibly provide access to the incredibly huge library of ROM and FOCAL 41 programs, plus of course offer a bit of homage to the 41, which seems appropriate. Absolute fidelity across this wide spectrum of programs drove the need to use the real ROMs in emulation, thus the speed penalty.

It's oversimplifying for sure, but I generally advise folks:

--Choose the DM42 if you want to write your own RPN programs, it's faster and enhanced FOCAL commands make it the best choice

--Choose the DM41X to access the enormous libraries of already written (and documented!) ROMs, User Library Solutions Books, PPC programs, etc.
