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!)
