In this video I finally provide some One ROM love for the Apple IIe, and show off some major new One ROM features including:

  • Header pins controlling external hardware
  • USB logging, including directly from the retro system
  • Control it all from the CLI over USB or from the retro system directly

Most features require firmware v0.7.2+. Firmware v0.7.2 should be released within a few days of this video being published.
