Excellent calculator and project

All the bad evaluations are really not justified. Go to more basic models, if you have basic needs...

This is certainly one of the best current project to develop the next generation all purpose scientific RPN calculator (HP should have done it but they have now unfortunately retired from this market).
ND0 and ND1 go beyond the best calculators ever designed by HP (in the 28, 48, 50G series). It is easier to use, has great programming features, is faster. The author seems very responsive. If you are a scientist or an engineer this is definitely an excellent choice.

The only missing feature for me is the CAS, but the interface with Wolfram solves partly this issue. A built in 50G CAS and this would become the dream machine...

The ND1 version is really cheap given all the features (unlimited stack, ...) A new HP50G is +100€...
