HP 32SII success and woes

[Bruce Larrabee]

The metal plate is grounded but only really matters if the unit has a buzzer and only when the buzzer has only one spring contact.

As for the gibberish on the screen, if there is a key or combination of keys that could cause this (a big if and I don't know the answer) then there could be a short in the keypad matrix. I see this all the time. If it is so it is possible to dismantle the keypad and clean the matrix. (I did one yesterday.) This is not easy though.

Whatever you do don't throw the calculator away!
