Scientific Calculator Keyboard Challenge II

Feeling creative?  Ever dreamed of the perfect calculator?  Here is a chance to design a calculator.  It can cover any part of mathematics you want:

*  Scientific
*  Financial
*  Programming/Graphing
*  Algebraic and/or RPN (Reverse Polish Notation)

Or if you want to go a specialized route, like Calculated Industries, consider:

*  Construction
*  Unit Conversion
*  Gaming
*  Geometry Applications
*  Civil Engineering
*  Physics 
*  Astronomy
*  Stock Market
*  Common Every Day Applications

It can be any combination!

Rules:
*  The keyboard must be used, including the arrow keys.  Assume that the calculator will have the necessary screen size.  You have 16 blank keys, of course, you can/should consider using shift and alpha keys.
*  The keyboard has a double-wide Enter key.  RPN and Hewlett Packard fans rejoice!
*  The marked keys must remain.  

Other than that, go wild!  Leave your creation in the comments.  

Have fun!

Eddie

P.S. If you want another design, I had a post where you designed a calculator keyboard using only 25 keys.  The link is here:

Scientific Keyboard Challenge, Revisited

On this post:

http://edspi31415.blogspot.com/2014/05/scientific-calculator-keyboard-challenge.html,

I have issued a creativity challenge: design a scientific calculator using only 25 keys.  No restrictions.  I came up with a couple ideas.

Before I present mine, I want to show a great landscape design by Picky Bart.  Thanks for posting PickyBart!:

---------------------

The first one is an RPN keystroke programmable calculator:

The next one is a graphing calculator. (or at least an attempt at one).  Since only 25 keys are allowed, this prevents the use of an ALPHA key.  So, soft keyboards via dialogue had to be implemented instead.

Modes:

RPN/Linear/Math IO

DEG/RAD/GRAD

FUNC/POLAR/PARAM/SEQN

a+bi, r<q, REALS

BIN/OCT/DEC/HEX

Language (dialogue bar)

Data:  Edit, Name, Delete

Stat: n, Means, Sums

Dist:  Norm PDF, Norm CDF; iNorm, Bin PDF, Bin CDF, Pois PDF

Pois CDF, Chi PDF; Chi CDF, iChi

List:  { }, sum, average, prod; seq, sorta, sortd, augment;

Dchg, size, position

Regr:  Vars (a, b, c, r), Regr (Lin, Log, Exp, Pwr, Inv, Quad, Cubic,

Sine)

Matrix:  [ ], det, trans, eigen; eigvect, size, position, ref;

rref, spec radius, rank, trace; LQ, LSQ, LU, QR

Prog:

File:  New, Edit, Delete

Input:  " ", Input, Prompt, Menu

Output:  Clear, Display, Output, Graph

Tests:  ==, >< , >, >=; <, <=, and, or

IFTE:  If, Then, Else, EndIf

Loop:  For, Step, Next; Repeat, Until, While, Wend

Ctrl:  Pause, Stop, Error, Subr

String:  length, sub, left, right; >expr, >string, position, augment

Math:

Frac:  PDQ, a b/c, exact, approx

Hyp:  (hyperbolic)

Prob: x!, nCr, nPr, gamma; rand, randint, randnorm, dice

Cmplx: abs, arg, real, imag; >Polar, >Rect

Parts: IP, FP, round

Calc:  derivative, integral, S, P

Constants: (24)

Conversions: (12 pairs)

Base:

Mark: b, o, h, d

HEX: A, B, C, D; E, F

Logic: and, or, not, xor; xnor, shift right, shift left, 2's

Utility:

RPN: swap, roll down, roll up, drop; over, pick, view, dupn

Solver: New, Edit, Delete, Solve

ALPHA: - enter message and press enter

CAPS (Keyboard), lower (keyboard), Symb (! @ # $ % ^ & * ( ) { } and math symbols), Greek  I may have forgot something but I think I got all the basics covered.

Scientific Calculator Keyboard Challenge

Design the keyboard of a scientific calculator and post links to your designs as responses to this blog entry. Rules:

You have only 25 keys to work with. That's it.

Whatever features, applications, special functions, number of modification keys you can fit is up to you. It can be simple, graphing, financial and/or complex. This blog entry is just a call to be creative and to have some fun. Here is one I did:

It is a relatively simple scientific calculator design that would be either a solar-powered calculator or an app. Features include linear regression, algebraic and RPN entry modes, and basic scientific functions.

If you partake in this, have fun and please provide links as responses.

Coming soon I will review two calculators I recently purchased: the Canon F-792SGA and the Casio fx-5800P N.
