I just received an HP 16c in cosmetically VG condition. It works fine, too ... except that the ENTER key has a strange, reluctant, "mushy" feel to it, almost as if there is dirt in there or something.
I have never opened a calculator in my life. How difficult would it be to open this unit up and clean it? And what is a safe method of cleaning?
Maybe I should just send to fixthatcalc, even though they have a big backlog/wait period.
Advice is welcomed. %^D
