Want a baby Macintosh Quadra 700? You can build one using Raspberry Pi
At Tom’s Hardware, we have a deep appreciation for Raspberry Pi projects, especially those that evoke the nostalgia of retro computing. One standout project by Branchus Creations transforms a Raspberry Pi into a miniature version of the Macintosh Quadra 700. The excitement of seeing this iconic computer recreated using modern technology is reminiscent of a holiday surprise.
Branchus Creations meticulously documented the build process, making it accessible for anyone to follow. The project involves creating a custom 3D printed case, designed by Branchus himself, along with integrating a Raspberry Pi 4 and various other DIY electronics components. This detailed documentation ensures that enthusiasts can replicate the build, using either a Raspberry Pi 4 or 5.
To create the case, Branchus used the web-based design tool OnShape, shrinking the original Quadra 700 design to about one-third of its full size due to printer limitations. The tool’s library of shared creations made it easy to find a model of the Raspberry Pi 4, facilitating the addition of mounting studs and holes within the case. The project exemplifies how modern design tools can bring retro projects to life.
For the internals, Branchus added a cooling fan above the Pi’s CPU and incorporated vintage-style audio by including 40mm speakers and a stereo amplifier board. He used the RetroPie operating system with the Basilisk emulator to run Macintosh System Software, specifically System 7.5.3. After some setup, the Raspberry Pi booted up just like a Macintosh Quadra 700, aptly named the Quadra 233, demonstrating its performance by running a classic game, bringing a piece of computing history back to life.
