I managed to send video signals to a Mac Classic’s internal CRT monitor from a BeagleBone Black back in 2016, and it seems like this is a topic that a lot of people are still interested in.

This article will explain how the timing of the Macintosh Classic CRT works and how I tried (and failed) to interface it with the Raspberry Pi, and how I successfully interfaced it with the BeagleBone Black’s PRU.

Once the screen came on, it was pretty disappointing: It just displayed a checkerboard, which seems to be a pretty common issue with these models. This problem is caused by a variety of issues.
