Macintosh SE/30 main logic board, as is typically photographed for
the sake of Internet forum communications and sales, as opposed to
reproduction-oriented photos.

These are copies of the official Apple Macintosh SE/30 schematics.
Source website: https://museo.freaknet.org/gallery/apple/stuff/mac/andreas.kann/schemat.html
Consult other sources for the BOMARC schematics. For example, from
Macintosh Repository:
https://www.macintoshrepository.org/875-macintosh-se-30-schematics-and-repair
The Internet Archive's BOMARC schematics copy. Use the Macintosh IIcx
schematics from the Internet Archive's source for reference since they
are practically the same as the Macintosh SE/30.
