# Macintosh SE Hardware
|
||
|
|
|
||
|
|
This is my effort to assemble all the pertinent hardware design
|
||
|
|
information on the Macintosh SE into a single coherent information
|
||
|
|
repository. The goal is to be able to have sufficiently detailed
|
||
|
|
information to, in theory, reproduce an identical (or nearly so)
|
||
|
|
physical, functional copy of the Macintosh SE.
|
||
|
|
|
||
|
|
However, my primary interest in having this information available is
|
||
|
|
to have detailed information for studying the Macintosh SE hardware,
|
||
|
|
and for maintaining existing Macintosh SE computers.
|
||
|
|
|
||
|
|
Conventional Macintosh emulator software prioritizes access to
|
||
|
|
application software without regard to the mechanical and electrical
|
||
|
|
design of the actual machine itself. My hope is that this repository
|
||
|
|
of information will enable the same kind of virtual access to the
|
||
|
|
hardware as we have to the vintage Macintosh software through the use
|
||
|
|
of conventional Macintosh emulators.
|
||
|
|
|
||
|
|
## What is currently available?
|
||
|
|
|
||
|
|
Currently, this repository only contains a vector graphics hand
|
||
|
|
trace-over of page 1 of the Macintosh SE Main Logic Board (MLB)
|
||
|
|
schematics. Typed text is used for all legible text. Since pages 2
|
||
|
|
and 3 of the MLB schematics are missing and nowhere to be found on the
|
||
|
|
Internet, they will have to be redrawn from the reverse engineered
|
||
|
|
printed circuit board layout.
|
||
|
|
|
||
|
|
Follow this link to [jump to the redrawn
|
||
|
|
schematic](old_artifacts/schems/retrace_se_mlb_p1.pdf).
|
||
|
|
|
||
|
|
There are lots of other independent projects with good pieces of
|
||
|
|
information out and about on the Macintosh SE. For the time being,
|
||
|
|
these are linked from documentation in the repository. In the event
|
||
|
|
the project has a potentially insecure future or lacks a durable
|
||
|
|
storage location, the pertinent information is copied into this
|
||
|
|
repository.

## License
|
||
|
|
|
||
|
|
Since a primary goal of this project is to assemble historic
|
||
|
|
information into a coherent repository, as much as possible, new
|
||
|
|
developments are released into the public domain. After all, as is
|
||
|
|
well understood in the vintage computing community, all patents and
|
||
|
|
copyrights are destined to eventually expire with the passing of
|
||
|
|
enough time, at which point the covered works cede into the public
|
||
|
|
domain.
|
||
|
|
|
||
|
|
Therefore, if you don't have an interest in exercising any exclusive
|
||
|
|
rights covered under copyright, you might as well simply declare your
|
||
|
|
works to enter the public domain early, rather than using a permissive
|
||
|
|
license or a copyleft license. For example, the CERN Open Hardware
|
||
|
|
Licence.
|
||
|
|
|
||
|
|
In the event that your jurisdiction does not have the concept of the
|
||
|
|
public domain, the Creative Commons Public Domain Dedication License
|
||
|
|
(CC0) is used as a fallback permissive license.
