Macintosh Portable
| Preliminary Information | |
|---|---|
| Release Year | 1989 |
| Leak Risk | High |
| Batteries | Yes |
| Mounting Technology | Through Hole (PSU), SMD (Logic Board) |
| Capacitor Types | Aluminum Electrolytic |
The Macintosh Portable was sold by Apple Computer from September 1989 to October 1991. 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.
