Greetings to all you folks who have seen everything. Specially you folks who have been around for a LONG time

I am trying to find information on a System of maintenance manuals called SYMBOLIC INTEGRATED MAINTENANCE MANUALS. This system was in use in several locations back in the 60s and early 70s.

In addition to carefully laid out schematics the system included a trouble shooting chart called a MAINTENANCE DEPENDENCY CHART.

I would appreciate any information on this system you might have.

I found one online mention of the "Symbolic Integrated Maintenance Manual", a mil-spec document (SIMM: MIL-M-24100A) produced by the Electronics Division of General Dynamics.

I don't know where you might find a copy, but a GD librarian or archivist might.
