HP-48GX key stiffness

[Steve Simpkin]

I find my HP-48G keys are a little bit stiffer than the keys on my HP-25 or HP-12C. They are a whole lot stiffer than the typical TI, Casio or Sharp calculator keys which are for the most part, mushy. The creaky sound is most likely from small gaps in the housing where the top and bottom halves of the calculator meet. Mine tends to creak more when pressing the upper 5-6 rows of keys and there is almost no creak sound when pressing the bottom two rows. I think what you are describing is fairly normal for a 20+ year old 48 series model.
