Known quirks
- PRAM battery leaks and corrodes the logic board — check before powering on
- Sony-designed chassis; first Mac with a palm rest and centered trackball layout
- No internal floppy — uses a detached external drive that often goes missing
- Passive matrix display ghosts heavily when scrolling
- Runs on sleep mode from AA cells in a pinch (design oddity)
