Applications

The Macintosh IIcx and IIci were Apple's mid-range professional desktop computers of the late 1980s and early 1990s, built around the Motorola 68030 processor and housed in the compact IIcx-style chassis. The AA15830 is a direct replacement for the original power supply in these machines, which are still actively maintained by vintage Mac collectors, educators, and retro computing enthusiasts. The IEC C13 pass-through outlet on the rear panel was a design feature of the era that allowed a monitor or second peripheral to share the same AC circuit as the computer. Replacement power supplies for the IIcx and IIci are increasingly difficult to find in working condition, making a tested original-spec unit a practical resource for anyone keeping these classic Macs operational.
