HP and DM key Pressure

[Dave Britten]

Thanks for sharing these, I've been wondering about this for some time. Somehow it never occurred to me that placing the calculator on a kitchen scale and slowly pressing the keys with a blunt object could be used to get force readings. Maybe I'll have to try that with my wife's electronic measuring cup and see if I can get some readings for the DM41L/DM1XL models.
