35s initial thoughts - Egan Ford - 07-26-2007 My 35s (S/N 1904) arrived from Walmart on July 21st. I just got home from a road trip. Today is the first day I got a chance to use it. Thoughts:
Re: 35s initial thoughts - Les Wright - 07-26-2007 I like the clamshell case but may use it for something else. Maybe putting some so The 33S slip case I always liked, and it is a perfect fit.

Re: 35s initial thoughts - Nenad (Croatia) - 07-27-2007 Quote: These times have certainly gone. From a point of view of an ordinary person (not a HP addict) who nowadays needs a calculator, what should be so exciting and outstanding in buying one? Finally, 35s is nothing more than a calculator. In most cases calculators do not mean anything at all to the generation who is now e.g. 14 to 24 years old. They are much more interested in mobile phones, but this is another story.
We have to face these facts. Maybe, the manual of my dishwasher starts with "Congratulations!", but who knows. Nobody of us at my home have ever read the manual, just started to press buttons...

Egan, what do you mean that you have missed 3 keystroke? Do you mean your fingers pushed wrong button?
Re: 35s initial thoughts - Egan Ford - 07-27-2007 Press "ENTER", nothing. Press again it works. Pressed "55", got "5".
Re: 35s initial thoughts - Katie Wasserman - 07-27-2007 I have found a few dropped keystrokes as well. My 35s also has a slight LCD alignment problem -- that's not too disturbing.
Re: 35s initial thoughts - Gene Wright - 07-27-2007 I wonder if the keys are being pressed too quickly, one after the other. If you look closely at the display, you'll see the BUSY indicator (it's a B) come on each time you press a key, whether digit or ENTER or ... Perhaps if the calculator is busy when you press the next keystroke, it isn't registering?
I have no idea what type of input buffer (if any) the machine has.
Re: 35s initial thoughts --> Lost keystrokes - Katie Wasserman - 07-27-2007 I thought that might be the problem too, keying too fast. But there does seem to be a keystroke buffer and it is 5 characters in length. Try doing a long computation time function like: 300 ENTER 150 nCr. While the calculator is busy type 1 2 3 4 5 6 ... at a slow/normal entry speed and when the function ends you'll get 1 2 3 4 5. Now do the same thing but type in 1 2 3 4 5 6 .... really fast and you see that the calculator misses some of the digits and might show that you entered 1248 for example. Admittedly this is not a normal thing to do, but I think demonstrates the missing keystroke problem. My guess is that the keyboard scanning routine isn't running fast enough to capture everything and the keystroke buffer isn't going to help this problem. Try the same thing on a 32SII, and you'll find the keystroke buffer is just 3 characters in length, but the keyboard scanning routine never misses any keys. -Katie
Re: 35s initial thoughts - bill platt - 07-27-2007 I don't get a "B". I don't have missed keystrokes.
Re: 35s initial thoughts - Egan Ford - 07-27-2007 Quote:No. It happened within the first 30 seconds, key presses were slow since I was not familiar with the keyboard. |
