Editing Macintosh Service Source

The '''Macintosh''' volume of Apple's ''Service Source'' is a '''79-page''' service manual covering the original Macintosh 128K and 512K (Apple's cover carries no model numbers at all &mdash; the volume is titled simply ''Macintosh''). The PDF was distilled on '''15 December 1995'''.

This page and [[Macintosh 128K/512K Service Source]] embed '''the same file'''. The fuller treatment of the manual &mdash; including Apple's ''Adjustments &rarr; Voltage'' procedure verbatim &mdash; is on that page; this page records the manual under the title Apple actually printed on it.

''Service Source'' volumes are '''module-level''' documents. They give Apple's own specifications, symptom charts, take-apart procedures and module part numbers, but they do '''not''' carry schematics, board-level parts lists or component values, so they cannot be used to source a capacitor table. Where a figure below is quoted, it is quoted as Apple printed it.
