RE: Calculator benchmark HP-28S
Hi, nice benchmark, I always notice that not all calculators, especially programmable, are easy t use. Same of them didn't spare keystroke at all.
Here how I will setup, enter the table without repetitions to get all individual X and Y results on responsible HP-28S. I presume this can be done exactly the same way on a HP-28Csince I don't use here any specific capability of the 'S' version but only setup the solver menu for interactivity and practical use with spare keystrokes. It is certainly possible to use the same trick on HP48/50 series, but I am unable to count the exact score since user interface, menu's access and keyboard are quite different on later RPL calculators. HP-28S f, [...] and (...) indicate respectively shift key, physical or soft-menu keystrokes. Code: SETUP Description Keystrokes DATA ENTRY and (X;Y) results DISPLAY through the powerful solver menu interface: Code: 3.12 (A) 2.56 (B) (LEFT=) (RIGHT=) Enter first data pair Score : 110 keystrokes EDIT: Just realize by writing this post that two more keystrokes can be spare when entering table 4th and 5th pair: Since 12.48 is 2 * 6.24, instead of typing 12.48 (A), one may spare a troke by entering A [,] A [+] (A) ( or A [SPACE] A [+](A) ). And the same trick can be used for the next entry : A [,] A [+] (A) instead of 24.96 (A) since \(24.96=2*12.48\). The final score of HP-28C/S may be reduce to 108 ! |
