Transistors, Not Apple, Revolutionized Computer Power Supplies

This article exposes how Steve Jobs falsely credited Apple with inventing revolutionary switching power supplies when the actual innovation came from semiconductor advances in the late 1960s–mid 1970s. The real breakthrough stemmed from improvements in switching transistor technology and control ICs, which emerged years before the Apple II. Accurately attributing technological progress matters for understanding computing history and distinguishing genuine engineering achievements from corporate mythmaking.
