From the project
An elegant solution to rebuild your failed Quadra 800, 840AV or Power Macintosh 8100 PSU.
$\color{#FF0000}{IMPORTANT!}$ Working with switching power supplies involves dangerous, potentially lethal voltages, even when the device is disconnected from mains power. Improper handling can result in serious injury or death.
This repository provides Gerber files and related materials in good faith to the Macintosh hobby community, without any warranty or guarantee of any kind, including safety, reliability, or fitness for any particular purpose.
