The article discusses a capacitor that was soldered incorrectly at the factory in Apple's Macintosh LC III, a 'pizza box' Mac model produced from 1993 to 1994. The capacitor, C22, was installed with its negative terminal pointing upwards, contrary to standard practice. This mistake could cause problems when replacing the capacitor with a tantalum one, as they are less forgiving when installed in reverse. The author verified this issue by examining the circuit and comparing it with other Mac models of the era.
