Key "bounce" - Keith Beyer - 03-27-2008 I recently acquired a couple of calculators that were in essentially "new" condition: 48GX and 28C. Both had significantly "tighter" keyboards than others I own, including another 48GX with black screen and 28S. Also, the first HP I owned (and still do), a 32SII also still has a "tight" feel.
Here's my question. Does a looser keyboard, including keyboard "bounce" develop from excessive use? Or have I just taken abnormally good care of my 32SII? I teach chemistry at the college level and have used my 32SII nearly every day during the academic year for the past 13 years. Or are some models more susceptible to keyboard degradation than others?
Re: Key "bounce" - jdgc (spain) - 03-28-2008 Among my oldest calcs, I own one 11c (bought 1988), a 48sx (1991?)
Of course this is subjective if you compare how you felt your kbd
I would say that 28S/C's have a much softer keyboard even out of

Re: Key "bounce" - Frank Rottgardt - 03-28-2008 I bought my 28S in 1991 and used it very heavy during my college years and later during my career. I also experience the 28S keys having a softer tactile feel (but nice) and travel than other HP calculators I own. But the keys did not change with time. My 48GX keys (Singapore made) are much harder than the 28S ones.
Re: Key "bounce" - Keith Beyer - 03-30-2008 Thanks for the feedback. Seems as though they experience has been that keyboards do not normally degrade as much as the two I have. I agree the 28C/S has a softer feel than the others even in "new" condition. However, the 48GX I bought recently has a lot of keys with "bounce" - slight movement before you fully depress the key to register on the calculator. It's very disapointing. I don't like the feel at all. Makes it seem like the keys are loose and sloppy. But, like I said, I only noticed the "tight" feel on keyboards of calculators I bought from people who said they were seldom used.
