(Long Message)
Dimitri, this is a long message but here it goes....
I think mine ended being a 28/48 approach but instead of RPL, it has keystroke programming:
KEYBOARD
SH-390G
GRPH ( PRGM ) MATH (lambda) TEST (mu) STAT (sigma)
F1 F2 F3 F4 F5
ALOCK ADV ? APP (+-) EQN $ XEQ &
ALPHA (LEFT) (UP) (DOWN) (RIGHT)
= A % B i C (angle) D
SHIFT x<>y R(DOWN) STO RCL
MODE D Sigma+ E Sigma- F CLEAR G
ENTER CHS (+/-) EXP (10^) Backspc
>HMS H SQRT I ^ P ROOT K ASIN L

Legend:
SHIFT ALPHA
PRIMARY
Menus: (F1, F2, F3, F4, F5) Mulit-page menus loop with MORE
GRPH: f(x)=, PLOT, ANAL, TRACE, VIEW (here you can change the viewing window - and gives xmin, xmax, xscl, xstep, and similar for y, theta, r, u, n, n-1 depending on graph mode)
GRPH-ANAL: VALUE, ROOT, SLOPE, EXTRM (Extrema), MORE; INTER (Intersect), SHADE, AREA, TEXT (Write on the Graph), MORE
PRGM: LIST, CREATE, CMD, DISP, LOOP
Programs and equations have 12-character names. Up to 10 programs and equations can also be assigned to 0-9 for quick access.
PRGM-List: List programs alphabetically, programs can be erased with highlighting it and hitting CLEAR, make a "quick-program" by highlighting it and pressing a number key; hence XEQ 0-9 executes programs labled 0-9
PRGM-CMD: LBL, GTO, RTN, BREAK, MORE; SF, CF, SF?, CF?, MORE
PRGM-DISP: INPUT, MSG (Message), PAUSE, R/S, MORE; ShowSt (Show Stack), ShowG (Show Graph), ClrSt (Clear Stack), ClrG (Clear Graph), MORE
Message Command: Use ALOCK to insert quotes (" "), i.e. to display "HP 41C" in a program: SHIFT ALOCK HP ALPHA 4 ALPHA 1 C SHIFT ALOCK MSG (PSE or R/S)
PRGM-LOOP: ISG, DSE, If, For, Do
PRGM-LOOP-If: IF, THEN, ELSE, ENDIF
If Structure: IF y x (test) THEN (true) ELSE (false) ENDIF
PRGM-LOOP-For: FOR, NEXT, STEP
For Structure #1: start end FOR var (cmds) NEXT
For Structure #2: start end FOR var (cmds) incr STEP
PRGM-LOOP-Do: DO, UNTIL, ENDO
Do Structure: DO (cmds) UNTIL y x (test) ENDO
MATH: Prob, Cmplx, Base, Num, HYP
MATH-Prob: nCr, nPr, Binom (Binomial CDF), Pois (Poisson CDF), MORE; NCDF (Normal Dist CDF), Ninv (Normal Inverse), CHI2CDF (Chi Squared CDF), CHI2INV (Chi Squared Inverse), MORE
MATH-Cmplx: ABS, ARG, REAL, IMAG, CONJ (Conjugate)
MATH-Base: (Prefixes) d, b, h, o, MORE; (convert to) DEC, BIN, HEX, OCT, MORE
MATH-Num: INTG, FRAC, INT÷, REM (Remainder/Mod), ROUND (Round y to nearest x)
TEST: x?y, x?0, AND, OR, NOT (First two gets you to <, <=, >, >=, MORE, =, ~= (not equal), MORE)
STAT: Means, Sums, Reg, x' (Predict x), y' (Predict y)
STAT-Means: MEAN (returns y-bar and x-bar), STD (standard deviation for both y and x), POPD (population deviation for both y and x)
STAT-Sums: SUM (Sy, Sx), SUMSQ (Sy^2, Sy^x), Sxy, n
STAT-Reg: Eqn (lists equation on stack), Corr, BEST (finds the best correlation), LIN (Linear), MORE; LOG (Logarithm), POW (Power),EXPR (Exponential), INV (Inverse y = a + b/x), MORE; QUAD (Quadratic), CUBIC (Cubic), SIN (Sinusodial), LOGIS (Logistic), MORE
APP:
F1 - MEM (Memory)
F2 - TVM (Time Value of Money)
F3 - RK4 (Differential Equation using 4th Order Runge-Kutta)
F4 - CASH (Cash Flow: Net Present Value, IRR, Net Future Value, Net Utility Stream, MIRR)
F5 - I/O (USB and/or Card Management)
ADV:
F1 - Constants Library (or Formula Library)
F2 - Conversions Library
F3 - ZETA
F4 - ERF (Error Function)
F5 - MORE
F1 - DATE+
F2 - DAYS (Days between dates)
F3 - DAYWK (Day of the Week, return a three letter code, i.e. "MON" for Monday)
F4 - Matrix
F5 - MORE
(** Date functions is a must for me)
ADV-Matrix: Entry, Add a Row, Add a Column, Delete a Row, MORE; Delete a Column, INV, DET, EIGEN (Eigenvalues), MORE; Row+, Row*, Row+*, IDEN (Identity), MORE
EQN: List, Create, CMD, Poly (Polynomials up to 6th order), Simultaenous (up to 6th order)
EQN-List: List programs alphabetically, programs can be erased with highlighting it and hitting CLEAR, make a "quick-equation" by highlighting it and pressing a number key; hence RCL 0-9 recalls equaitons 0-9
EQN-CMD: EVAL, SOLVE, Sum, Integral, Derivative
MODE: RUN, BASE, ANGLE (Deg, Rad, Grad), GRAPH (Function, Parametric, Polar, Sequence), DISP (All, Fix, Sci, Eng)
F<>D: Toggle between Decimal and Fraction display mode.
In fraction display mode, the following are displayed: fractions, exact square roots, and pi (I guess this is EXACT mode)
Enter fractions like this: whole number, decimal point, numerator, decimal point, denominator (like the HP 35s)
In decimal display mode: everything is a numerical approximation
Memory Capacity:
(at least) 100,000 program steps
(at least) 15,000 bytes for statistics, equations, and matrices
