  • IIGS Control Panel access from 8bit software

    I've got a question on the Control Panel access... when in 8bit emulation mode, is it possible to 'lock out' the Control Panel. It seems i have done this by accident... are there any 8bit switches that 6502 or Applesoft can touch to re-enable (or disable) the control panel?
    Also for reference, is there anything else related to the control panel, other then
    the standard Change the Color, Change the Speed ect you can do with soft switches?
    Thanks a ton- Tom

    Yes, you can lock out the control panel by disabling interrupts with "SEI". Just go to the monitor and do:
    300: 58 60
    300G
    Text color, background color, border color, processor speed are the only ones really needed to be accessed from a running program as the rest of the settings don't need to be adjusted on the fly.
    The keyboard layout can be changed from softswitches
    And the keyboard data register can be read with softswitches
    The mouse and clock should be set up in the control panel, but the mouse coords and clock can be read from softswitches.
    And all control panel settings are adjustable through a tool call that loads or stores the battery Ram.
