These key codes are used for keyboard to 680x0 communication, and are not associated with a keystroke. They have no key transition flag, and are therefore described completely by 8-bit codes: 78 Reset warning. Ctrl-Amiga-Amiga has been pressed. The keyboard will wait a maximum of 10 seconds before resetting the machine. (Not available on all keyboard models) F9 Last key code bad, next key is same code retransmitted FA Keyboard key buffer overflow FC Keyboard self-test fail. Also, the caps-lock LED will blink to indicate the source of the error. Once for ROM failure, twice for RAM failure and three times if the watchdog timer fails to function. FD Initiate power-up key stream (for keys held or stuck at power on) FE Terminate power-up key stream. These key codes will usually be filtered out by keyboard drivers.
