I picked up a little old Tandy 1650 chess game this morning. Batteries are
still in it, of course, corroded to heck and back again - but thankfully
the PCB seems unharmed.
The lower half of the case shell is just the battery compartment and one of
those disc-type piezo buzzers, with lugs on the case melted to hold the
buzzer in place. After treating the battery terminals, can I dunk the case
half - buzzer and all - in water? I'm not sure if those buzzers are sealed
units or if water will end up where it shouldn't be and cause damage.
cheers
