It's quite clear, as has been mentioned before, from endlessly watching this clip that the box Ripley squats down to operate is not the box that houses the main Self Destruct prop we see. From this pic u can see she is using a calculator type keyboard, totally unlike the actual prop keypad
Love it already...great prop making as usual mateFound a bit more time to work on this...mocked up the lever boxes. Need to tweak the lower box and add the metal bits but progress is made
