HP 35s, keyboard buffer, bug, feature or what?



#5

I just made the following interesting discovery. I used my 35s to add the following numbers:

2 + 3 + 2 + 2 + 1 + 2 + 2 + 1 + 2 + 2 + 0.5 + 1 = 20.5

When doing such an operation, I use my left thumb for keying in the numbers and my right thumb for pushing the "+" key. I can do that really fast without looking at the keyboard. My 32sii gives the corect answer, always, regardless how fast I am. But on the 35s it is pure luck to get the right answer. Here are some answers: 4323.04; 38.5; 4937.04; 20.5; 20.5; 39; 20.5; 57

It seems that there is a problem with the key buffer, or the machine responds too slow. When operating the keys too fast, the "+" operation is not executed.

Am I the only one with this problem ?

I had no problem with this. I repeated the calculation three times and constantly got the correct answer.

Nope. Pressing and releasing the binary operator keys real fast results in missed strokes. The numeric keys don't seem to have that problem. I noticed this some days ago.

However, that was just a test, the speed necessary to miss the operator is beyond what I actually use.

I tried that sequence on my 35s (and a 17bii+ I had nearby) with no problems other than the occasional fat-fingering it on my part. I did the run several times so that I could get it pretty fast, and even after multiple attempts, I got the correct result.

Are you REALLY REALLY REALLY fast?? :-) Just too fast for any modern calc?

thanks,
bruce
