Performance Index | The performance strongly depends on the
calculator settings:
"Numeric" can be found in the HP-49G MODE/CAS settings. When checked constants are replaced by values which apparently slows down execution.It must be ensured that integer numbers have trailing decimal points in order to achieve optimal performance. |

Comment | A rather big and very powerful machine. HP-49G with ugly rubber keys with no feedback at all! Unfortunately, it is completely impossible to use the unit without a manual. The key labels aren't self-explanatory at all. In the beginning the unit felt rather sluggish. However, after I reduced the keyboard response time using a "300 ->KEYTIME" command this is much better! www.dynatech.de offers a HP-49G SpeedUp kit which over-clocks the CPU by a factor of 2 or 3. Apparently, the speed-mode can be turned on and off. The disadvantage is that the date & time functions don't return correct values any more. HP-49G+ keyboard with its hard plastic keys is much better than the HP-49G keyboard but still cannot rival the traditional HP keyboards. Furthermore, the key clicks make a hollow sound inside the plastic housing which gives a quite cheap impression. And finally, feeling the key click doesn't necessarily mean that the unit recognized the keypress! Sometimes the click occurs but the key has to be pressed a little harder before the associated action is executed. This makes it impossible to type without looking at the display. The display is significantly larger than in the HP-49G so that 7 instead of 5 stack entries can be displayed. Note that the keyboard layout of the HP-49G+ is identical to the HP-48GII. Also, the software versions are (more or less) identical suggesting that the only real difference is the additional memory and the SD card slot of the HP-49G+. Both the HP-48GII and HP-49G+ have a strange behaviour where the display seems to be redrawn about 3 seconds after the last change of the display contents. This is especially nasty when the blinking edit-cursor is visible because it constantly triggers the display refresh. As a consequence the blinking cursor does not blink steadily but more or less randomly. For a number of keyboard shortcuts see the HP-48GII. For a comparisn of the HP-38G/39G/40G/48XX/49G see this overview. Daily practical use of the HP-49g+ revealed that it is quite battery consuming, even when turned off. |
