macse30mlb
macse30mlb is primarily a modern redrawing of the Macintosh SE/30
Main Logic Board schematic drawings, drawn in KiCad. The resulting
schematics are much more legible and easier to work with than the
original scans.
Want to check out what the original schematics look like? Take a look at this site for copies of Apple's original schematics.
https://museo.freaknet.org/gallery/apple/stuff/mac/andreas.kann/schemat.html
For convenience, a script to download the files into your local working repo space is also included in this repository.

Future Ideas
What else can be done with this KiCad project?
-
Construct a Bill of Materials (BOM) for capacitor replacement (recap) projects. Or, alternatively, use this project as a means to organize the countless recap SE/30 BOMs already out there!
-
Construct a custom silicon salvaging diagram and Bill of Materials. A useful reference to determine the most important parts to save from dead logic boards. Likewise could be done for discontinued parts.
-
Create a modern Printed Circuit Board (PCB) layout. Modern PCB manufacturing services can then be used to order replacement PCBs.
-
Create a 3D model of a Macintosh SE/30, with accurate internal geometry. Suitable for 3D rendering, and maybe even 3D printing of a Macintosh SE/30 placebo. This can be especially interesting for 3D renders with a translucent/transparent case.
