Hello everyone
My keypad buttons from my hp8563A badly responds.
On ebay i can find replacement keypads for a hp8563E but does this fit on a hp8563A?
Regards Ben

You need to check if the part numbers are the same for both keypads. Also, your keypad may be able to be dismantled and cleaned (with a fingernail to clean the carbon on the buttons and some iso alcohol for the contacts on the PCB-I've just cleaned the keypad on my HP8563E). You need to do some research.
