General Information · Repair Cautions

The original Macintosh Color Classic, was sold by Apple Computer from February 1993 to May 1995. Like all Macintoshes of its era, its original surface-mount electrolytic capacitors leak their contents and require replacing for both functionality and to protect critical traces on its circuit board from being eaten by electrolyte.

Known Issues

Maxell Battery "Bombs"

Causes

Apple placed a small lithium battery on the Macintosh Color Classic's Logic Board to power and preserve the contents of the Parameter RAM (PRAM). Apple used a number of different brands of battery for this purpose, one of which is Maxell. Maxell lithium batteries are notorious for rupturing in storage and spewing its highly corrosive contents all over the board. If your Macintosh Color Classic is still intact with its original PRAM battery, THE BATTERY MUST BE REMOVED IMMEDIATELY, even if it is not Maxell brand.

Solutions

Macintosh Color Classics with exploded PRAM batteries are pretty much irreparable, save for replacing the entire Logic Board.
