33s - If a wish-list were solicited..



#7

I'd suggest the following improvements:

1. Multichar variables (even limited to 3 would help)
2. Eqn editing w/out having to backspace (the direction key)
3. GTO for equations lib (jump to any eqn), or basic directories.
4. Ability to call on a stored equation from within a program.
5. Slightly smaller keys (more space between them).

I'd have no need for a bulky graph calc if the aformentioned were incorporated in a future model.

ECL's HP-33S wish list:


  1. Multichar variables (even limited to 3 would help)
  2. Eqn editing w/out having to backspace (the direction key)
  3. GTO for equations lib (jump to any eqn), or basic directories.
  4. Ability to call on a stored equation from within a program.
  5. Slightly smaller keys (more space between them).

Regarding item 1: This would be very useful in certain situations, but would likely require a change of paradigm, and result in some inconsistency how variables are handled. Such things must be thought completely through. (Would one really want to introduce the complexity of the 42S?)

Item 2: Agreed. I would add "support of implicit multiplication" to make equations more compact -- e.g., 2(X+Y) instead of 2*(X+Y).

Items 3 and 4: Also agreed, but this would require the ability to assign an identifier to each stored equation. Maybe an "EQN" command that would work similar to the flexible "MATRIX" on the HP-15C? (e.g., RCL MATRIX A", "MATRIX 9").

Item 5: Not entirely agreed. I would advocate a return to the colors and form factor similar to the original 32SII.

I would also ask for good and complete complex-number mathematical functions, at least as good as those in the 15C and 42S. The functions that are present -- besides being incomplete -- are quite helpful for programming, but are cumbersome for inteactive calculations.

Wish list of 33S:

1. Multivariable names
2. Numerical label numbers, steps are included with each program
3. Classic HP colors, I really like the 48S series color scheme
4. Derivative and summation function (although they can easily be programmed)
5. Input Equation prompt

#10

Wish list: An HP-41 style keyboard and color scheme.


#11

Yours is the best wish of all, almost any old HP case and keys would be better than what it currently is.

#12

Agree with your suggestions, I would also like to see a large enter key again, and a return to the classic colors. I can handle the green secondary functions on the aluminum face plate, but I don't like the purple. Also, to my eyes, the dark purple gets lost on the dark right-shift key. I want rectangular keys again, I think they should abandon the "chevron" layout. I don't like styling gimmicks, so I would prefer something similar to the voyager or pioneer series.

What I hope they keep on future models (hopefully there will be future models) are the 2 line screen, a cursor key, and the separate buttons for solve, modes, and display. And it goes without saying, but I'll say it anyway, KEEP RPN!!! I also like the large memory, though it's hampered by the single character variable names. It allows me to put messages in my programs, however.
