Just as the real thing once ran Classic Mac OS, Action Retro set up his Pi to immediately boot into an emulated instance of Mac OS 9.2.2, complete with a startup chime, plus internally- mounted fans, thereby creating an accurate representation of the original machine as it was. Using the power of soldering, 3D printing, and careful OS tweaking, a fellow on YouTube by the name of Action Retro has managed to successfully convert his Raspberry Pi 3 Model B into a downsized Apple Power Mac G3.Īesthetically, the blue and white-colored case that the Pi resides in is a plastic housing modeled after the PowerPC 750-based Power Macintosh G3 Blue & White, which was originally released by Apple in 1999 as the professional version of the iconic iMac G3.
