Macintosh Portable M5126 RAM Logic Schematics

[dc99]

As part of solving a sad mac issue on an Apple Macintosh Backlit Portable (m5126) I ended up drawing out the RAM logic which others might find useful.

I've checked it twice however it's the first schematics I've ever drawn so any issues let me know and I'll make the corrections.

thank you!! Would you happen to have the video schematics by any chance?

The M5126 shares the majority of the same schematics with the M5120 which can you find online and contain the video section. The key differences between the models are the ram logic and hybrid module.
