• no x^2 ? I would expect this function on any basic scientific calculator
• DISP menu: I would remove E3ON & E3OFF, and have E3ON by default. This would simplify the DISP menu and provide a consistent way to access ALL, FIX, SCI and ENG modes: shift DISP A or F or S or E Enter
• MORE menu: you have NEXTP, why not PRIME?
• what's the usage of alpha on the Enter key?
• there is H.MS : is it as on the 34S just affecting the display or is it like ->H.MS and in this case where is the inverse function ->H ?
  

Answers in the same order:

• I recommend using ENTER x for x²; it's fast, simple, and the one level lost doesn't matter with 8 stack levels.
• OK. Good idea.
• NEXTP returns the same information If you see the same number as before you know it's a prime.
• H.MS is as on the 34S (the function set is a pure subset of the 34S'). I'll print an H in front of .d ...
