had to design a 3D printed adapter to mount the modern LCD panel to the Mac’s frame, and while he was at it, he also came up with printable dummy parts to fill in the various openings on the case that are no longer necessary. Essentially the only things inside the case are the 10 inch 4:3 LCD panel, the Raspberry Pi, and a small adapter that turns the Mac’s pre-ADB keyboard into standard USB HID. Things are naturally made a lot easier by the fact that the modern electronics take up a small fraction of the Mac’s internal volume. In the video after the break, walks viewers through the process of mounting the new components into the nearly 30+ year old enclosure. Mounting the LCD and associated electronics.

Luckily, he decided to forgo the fish and instead outfit the case with a new LCD display and Raspberry Pi to emulate Mac OS 7.5. But its owner never found the time to take on the project, and instead gave it to. Like many before it, this Mac 512K case was originally slated to get turned into a kitschy desktop aquarium.
