I’ve spilled some sauce on the front of the calculator and want to remove the motherboard from it’s frame (to acces the front). But it seems to be fixed to the frame with black plugs, which are not screws in any way. Is there no option to remove the motherboard?
Well, you technically can, but it’s really hard, and your probably wont be able to get it back on the way it was. I believe there are some plastic pegs you need to break to remove it. It’s also probably glued in some places.
