	* '''Reel ~~motors~~''' ~~with worm gear assemblies (operating temp ~40°C)~~		* '''Reel fortune disks''' - older design then "One Hand Bandit" - spins horizontal and clockwise rather then vertical!
	* '''Electromagnetic brakes''' – normally-engaged, ~~4-wire position-lock mechanism on gear wheels, driven by BD675 Darlington transistors~~ at 24V (~~~545mA per coil~~, ~~44Ω~~, ~~80% duty cycle)~~		* '''Electromagnetic brakes''' – normally-engaged, unlock to allow disk spin. Heats up a lot at 24V from PSU.
	* '''~~Sonderspiele~~'''		* '''24V LEDs''' - Plenty of LEDs (30), originally it was bulbs, replaced with orange LEDs for extra vintage feel and lower heat, power consumption is the same.
			* '''5 OG Buttons''' - Bottom part, to control the game.
