The '''Power Macintosh 4400''' volume of Apple's ''Service Source'' is a '''132-page''' service manual covering the Power Macintosh 4400/200 and 4400/200 PC, the Far East Power Macintosh 7220/200 and 7220/200 PC, and the Europe-only Power Macintosh 4400/160. The PDF was distilled on '''20 February 1997'''.

The '''Power Macintosh 4400''' volume of Apple's ''Service Source'' is a 132-page service manual for the Power Macintosh 4400/200 and 4400/200 PC, the same machines sold in the Far East as the Power Macintosh 7220/200 and 7220/200 PC, and the Europe-only Power Macintosh 4400/160. The PDF was produced in FrameMaker and is dated 20 February 1997.


''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.
Like other ''Service Source'' volumes, it works at module level: a Basics chapter, specifications, symptom charts, take-apart procedures, upgrades, battery and reset procedures and an exploded view.

Revision as of 19:04, 30 September 2026

The Power Macintosh 4400 volume of Apple's Service Source is a 132-page service manual for the Power Macintosh 4400/200 and 4400/200 PC, the same machines sold in the Far East as the Power Macintosh 7220/200 and 7220/200 PC, and the Europe-only Power Macintosh 4400/160. The PDF was produced in FrameMaker and is dated 20 February 1997.

Like other Service Source volumes, it works at module level: a Basics chapter, specifications, symptom charts, take-apart procedures, upgrades, battery and reset procedures and an exploded view.
