Comparison Between HP 17B and 17BII+

 Comparison Between HP 17B and 17BII+


This is a quick comparison between the original HP 17B and the current (since 2007) silver HP 17BII+ calculators. I hope the 17BII+ is still being produced and sold, it has been quite a while since an update to the 17BII+.  


The main features of the 17B family have remained constant since the original 17B came to the markets in early 1988:


*  Time Value of Money with Amortization

*  Business Calculations including Percent Change, Cost/Sell/Margin/Markup

*  Four Regression Models:  Linear, Logarithm, Power, Exponential

*  Bond Calculations

*  Depreciation including Straight Line, Sum of the Year's Digits, and Accelerated Cost Recovery

*  Days Between Dates, 10 Alarms, Clock

*  10 Memory Registers with Storage Arithmetic

*  Can use the HP 82240 Infrared Printer (82240A/82240B); even though they are well out of production by now

Now for the differences:


HP 17B:  (1988)

*   Available Memory:  6,752 bytes

*   Batteries:  3 x LR 44

*   Case Colors:   Brown, Peach-Orange shift key and text

*   Shift functions are printed above the keys


HP 17BII+:  (2007 - present)

*   Available Memory:  about 31,000 bytes

*   Batteries:  2 x CR2032

*   Case Colors:  Silver, Electric Blue shift key and text

*   Shift functions are printed below the function

*   Double line print option  

*   Currency conversion mode

*   RPN mode (this was added to the HP 17BII in 1990)


I did a quick speed test on the equation:


Σ(I:1:525:1:I)  (Result:  138,075)


The original HP 17B won the speed test.

That is about it.   I love the 17B series, which has a rich set of financial functions and a robust solver that includes ore functions that most calculators have.  (including integer part, fractional part, signum, solve if, Σ, date functions, and yes, the Let and Get functions!)

Differences Between HP 32S and HP 32SII

 Differences Between HP 32S and HP 32SII




The HP 32S and HP 32SII are two classic RPN calculators which feature a rich set of scientific calculations, including logarithms, trigonometry, hyperbolic functions, integer part, fraction part, absolute value, statistics, and linear regression (y = mx + b).  Both are keystroke RPN programming programs with a capacity of 390 bytes.  


What are the differences? 


HP 32S


*  Production:  1988 - 1991


*  Keyboard Colors:  dark brown, almost black keys; one orange shift key


*  One key deals with scrolling:  down, with up shifting


HP 32SII


*  Production:  1991 - 2002


*  Keyboard Colors:  dark brown keys, orange shift key, blue shift key (1st edition); black keys, green shift key, pink shift key


*  One key deals with scrolling:  down, with up shifting


*  Has four sets of US/SI conversions:  kg/lb, °C/°F, cm/in, l/gal


*  Pressing the decimal key ( [ . ] ) twice will create fractions and mixed fractions.   The FDISP toggles between decimal approximation and fractions.  



Menu HP 32S HP 32SII
PARTS [ shift ] [ x<>y ]: IP, FP, RN, ABS [ |> ] [ √ ]: IP, FP, ABS (RN is on the keyboard)
PROB [ shift ] [ 3 ]: COMB, PERM, x!, R# [ |> ] e^x
STAT/LR One group of menus Split into four menus
SHOW [ shift ] [ . ] [ |> ] [ ENTER ]
SOLVE, ∫ [ shift ] [ 1 ] SOLVE: [ |> ] [ 7 ]; ∫: [ |> ] [ 8 ]
LOOP: ISG/DSE [ shift ] [ 5 ] ISG: [ <| ] [ 9 ]; DSE: [ |> ] [ 9 ]
TESTS [ shift ] [ × ]: offers < = ≠ > x?y: [ <| ] [ ÷ ], x?0: [ |> ] [ ÷ ]: offers < ≤ = ≠ > ≥

Hewlett Packard would later release updated versions of the 32S with the ill-fated 33S and the better but not perfect 35S.
