Quirks
- If you are trying to boot into Copland, you can't start holding down the Caps Lock key too early or it won't be detected, and you can't start holding it down too late or you'll already be booting into System 7.5.
- If you set the DB-15 adapter to VGA mode, the video adapter flips a coin on reboot to see if the display is detected as 1024x768 @ 70 Hz, 640x480 @ 60 Hz, or as something that is definitely incompatible with my monitor.
- It doesn't like booting from certain Classic Mac OS CD-ROMs that should be bootable.
- Whether or not the speaker works is decided by a coin flip on each reboot.
