Known quirks
- First Apple II with 16-bit CPU (65C816) — backward compatible with 8-bit II software
- Ensoniq 5503 sound chip — 32-voice wavetable synth rivaled dedicated synthesizers of its era
- Original ROM 0 boards shipped with a design flaw — battery leaks destroy logic boards
- Upgraded Apple IIe Woz-signed variant gave users a ROM-0 board in a IIe chassis — collectors prize
- GS/OS was a full windowed GUI — the forgotten sibling of the contemporary Mac System
