An S+ board connect to a monther board located below the main board , older versions have it on the side of the machine.
S-SLOT ( RS ) machine always have the baord at the back of the machine , somtimes like the australian version in the top box and the looms of the machine connect directly to the board.
An S+ machine has a gap for a speaker on the front of the machine in the tray below the belly glass.
An RS board only uses one EPROM and S+ can use one or two.
An RS EPROM can work on an S+ board , but not visa-versa.
An RS game does not support reverse reel features.
