 <!-- 
    Built-in printer is NOT emulated as such.
    Based on dumps by Peter Hanraets on machine with serial number 781 04902
    Firmware switch not emulated yet, now always on 'enable'. When the switch
    is on disabled on the real machine, slot 2 is totally empty (0xFF). It
    seems to be connected to the /OE signal.
