Does anyone know if there are any other 39 and 49key contact boards that are compatible with with the hp126. Does any 49 key board work, or am I just going to have to repair the blown resistors. Just curious, I know the parts are almost nonexistent at this point. But am just curious.
It may be enough to clean the contacts with IPA, perhaps also the contact strips !
Most boards are specific to the keyboard.
Are the resistors blown because they’ve been water damaged? Do you have a photo?
