Macintosh II: Loose Speaker Brackets



Under some conditions, the brackets do not adequately secure the speaker
to the lower pan in the Macintosh II. If the Macintosh II is handled
roughly during shipping, the speaker may break loose, while the wire
harness usually stays connected to the board. The speaker then swings
around inside the computer, possibly cracking the main logic board or
causing a hazardous short.

Use a wire butterfly snap hold device similar to the Apple IIe speaker
hold down assembly. In fact, the Apple IIe speaker hold down device could
be reworked to be used in the Macintosh II. The existing support bars
around the speaker can accommodate the wire butterfly snap hold device
adequately.
