Known quirks
- First mass-market personal computer with color graphics — sparked the home-computer boom
- No lowercase support in the original — bundled monitors displayed ALL CAPS
- Motherboard designed by Steve Wozniak and considered a masterpiece of minimalism
- Disk II controller added later (1978) — original units shipped cassette-only
- Most surviving units have leaky RIFA filter caps in the power supply that must be replaced
