Applications

The AA11040B is the stock power supply for the Apple II and Apple IIe, two of the most influential personal computers of the late 1970s and early 1980s. The Apple II, introduced in 1977, was one of the first mass-market microcomputers to ship fully assembled with a color display output and an expansion slot architecture; the IIe followed in 1983 with an enhanced keyboard and greater memory capacity. This power supply feeds the main logic board and up to seven expansion cards in the Apple II's internal slots, making a functional PSU critical for any working system. Today these machines are maintained by vintage computing hobbyists, collectors, and educational retrocomputing programs — a working original power supply is one of the more sought-after replacement parts, as original units are aging and failures are common. The AA11040B is a direct, drop-in replacement for a failed unit in any standard Apple II or IIe case.
