You are buying a Dot Matrix LED Display 128 x 32, reddish-orange, 5VDC LOW VOLTAGE operation in excellent tested condition. The 1990-2005 pinball machines used DMD's that required nearly 100 volts, which can kill a person if you touched the wrong terminals, these use only 5 volts, much safer. I will include an adapter 

 so that you can use this LED display in older Stern, Bally, Williams, Data East, Sega machines, those are the machines that have a large 8-pin molex connector for the power supply and a smaller connector for data input, just let me know what machine you are using it on--the older machines were plasma displays whereas this replacement is LED, which I think has a better appearance anyway. The pictures show the display in an older Williams machine.
