The Apple II was the first computer I ever used. This is a IIe I recently got on eBay, but unfortunately, it is not working. When I plugged it in, I saw smoke coming from what, I think, is a capacitor on the C15 position on the board. Next step, figure out what that part actually is and order a replacement.

A disassembled vintage computer with its circuit board exposed is placed on a workbench alongside a tablet displaying information, a multimeter, and other electronics tools.

I have no experience with electronics, multimeters etc. This is definitely going to be a long-term adventure.
