Today I'll cover a bit more about the special function 'hot' keys when using the PS/2 keyboard with the NUC.
Used in combination with the
The following functions are non-volatile in nature, meaning that whatever their last known state was, that will get retained between power-ups.
SCREENSAVER: CTRL+ALT+S to toggle
ALT+S to view setting
Enables or disables the Atari 'attract' mode. When disabled (OFF) a CTR+SHIFT+A is sent once every 3 minutes to reset the attract timer. Normally this is considered a 'null' key send by the Atari OS and will be ignored.
XRAM MODE: CTRL+ALT+X to toggle
ALT+X to view setting
Selects between two different extended RAM modes. Either 256KB Compy Shop, or 512KB Rambo. Compy Shop mode allows for separate CPU/Antic access to the RAM.
VGATE MODE: CTRL+ALT+V to toggle
ALT+V to view setting
Toggles VGATE chip ON or OFF. When it's ON, over scan is limited to what would normally have been visible on a CRT screen, thus eliminating graphic garbage produced during certain games or demos in the bordering areas on wider screen displays (LCDs). The NUC also has an LED showing the present state of the VGATE chip, so you should see this turning ON and OFF depending upon the last setting.
NumLock: CTRL+ALT+NumLock to toggle
ALT+NumLock to view setting
This toggles the power-up state for NumLock, which determines if the numeric keypad will either be in number mode or navigation.
Pressing the NumLock key without ALT, simply toggles the mode without saving or changing the power-up state.
Key Map: CTRL+ALT+F4 to select
ALT+F4 to view setting
There are 4 key maps that can be selected.
