Mods in mine are :
El wire on wire-ramps (very dim at 6.3V)
RGB-LED strip behind Rod Sterling and the door.
Flashing leds behind the plastics of powerfield, activated by REED-switches.
Great theme with nice modes refering to the shows. And the Twilight Zone song of Golden Earring .
Love the stop and go type of game when accompanied with fast flow pins.
