Quadra800rom Work [2021] «EASY»
Apple engineers famously hid in these ROMs. For example, on the Quadra’s predecessor (the IIci), setting the date to the machine's release date and holding specific keys would show a secret photo of the development team. While the Quadra 800 doesn't have an identical photo egg, it contains hidden code for the "Stolen from Apple Computer" icon, designed to catch clone makers who might try to copy the ROM data.
